Here’s a recent example from X that finally pushed me to write about it:

First, let’s look at what those safer ways are. We’ll compare high stakes, high risk play with low stakes, low risk play. And we’ll look at what happens when there’s no other choice.

Most of the US advantage players I’ve talked to use the same scheme. Say a casino offers 100% cashback on losses up to $1,000. These players bet both sides. On one account they put $1,000 on Banker in baccarat, on another $1,000 on Player.1 One account wins, the other loses and gets its thousand back as cashback.

Simple math: if Player wins, you’re up exactly $1,000. If Banker wins, you’re up $950 because of the 5% commission. Banker wins a bit more often, so on average that’s about +$975. But that used up two promos, so the $975 has to be split in half. That’s about $487 per promo.

Almost 50% ROI on a promo with zero risk. Sounds great. But you can do better.

A Brief History Lesson

People were already doing this back in the 2000s at offshore casinos, when bonuses looked pretty similar. You could deposit $500, get a $500 bonus and clear it by betting $480 on red, $480 on black and the rest on zero2.

When I started wagering bonuses in 2016 at offshore European casinos, a lot of people thought bonuses were dead. Almost everywhere, low risk bets like baccarat or red/black in roulette were banned by the bonus terms. Low house edge blackjack was banned too, of course. On top of that, wagering requirements started at 35x, which made small risk free bets pointless. So from day one, this scheme just wasn’t an option for me.

When we were talking about max bets and max EV, one of my US subscribers told me that European casinos are way too sophisticated with all their terms. In the US it’s much simpler. The terms are simple, the bonuses are big, and nobody needs extra risk. Everyone plays it as safe as possible.

US casinos aren’t that sophisticated yet. Neither are the players, so the casinos don’t really have to try. The market is still immature.

I think a big part of it is that online casinos in the US haven’t been legal for very long. The market is huge and rich, and nobody worries about a small percentage of players exploiting bonuses.

To me, that explains why DraftKings in 2023 was spending hundreds of millions a year on promotions without really knowing how they worked3.

By 2025 they were spending $3 billion on promotions out of the $8.7 billion players lost. And this time they had a model that gives promos to the people who lose the most.

It’s quite possible they’ll eventually build a model to stop giving bonuses to the people who win. And to spot those players early, right after sign up or the first deposit, the way sportsbooks already do.

In Europe the market is smaller and more players are exploiting bonuses. It’s been around for a long time and the terms aren’t that good anymore. But the US could go the same way.

That said, as we saw above, this method still works in the US. So let’s compare the pros and cons of this strategy.

Min Bet, Min EV and Min Risk

The biggest upside of this approach is that you play it safe, risk nothing and steadily take profit. And if the casino refuses to pay you out, you won’t lose that much in winnings.

But there are downsides too, and some of them aren’t obvious right away. First, it’s not exactly legit. I’d even call it cheating. Not that I judge anyone for it. But technically it gives the casino a great reason to keep your money if it ever comes out. Maybe even sue you. Hypothetically.

Second, it gets obvious really fast. If you clear every bonus this way, anyone at the casino who looks at your account will instantly see you’re exploiting the system. And sooner or later they’ll shut it down.

Third, plenty of offers just don’t work with this method. More on that below.

Max Bet, Max EV and Max Risk

Putting $1,000 on 17 black has one feature that’s both its biggest advantage and its biggest disadvantage: huge variance. Because of the big downswings, the casino doesn’t immediately realize you’re playing with positive EV. That’s the upside. The downside is that you’re the one who has to sit through all those losses and downswings.

Your EV here comes from the cashback, so the more often you collect it, the higher your EV. There’s a big difference between getting cashback every other time, like with baccarat, and 36 times out of 37, like with a bet on a single number in roulette. That’s why putting everything on a number gives you an EV of about $9464.

The biggest upside: you’re playing with maximum EV. In the baccarat scheme, both accounts have a promo, but in each round only one of them loses. The cashback kicks in on that one, and on the other it just goes to waste. Bet $1,000 on a number on the same two accounts and you get $1,892 on average instead of $975.

There’s also no pattern of steady wins, which makes you harder to spot. The casino thinks you’re a good VIP player. It gives you better terms, sends gifts and so on.

And for some bonuses there’s simply no other way. You either pass or accept the risk.

The biggest disadvantage: the downswings can be brutal. Once I was down $200,000 while playing with positive EV, because my number didn’t hit 200 times in a row. That happens in about 0.4% of cases. Unfortunately, it wasn’t 100% cashback, so I didn’t get that $200,000 back. But I’ll write about that later.

When There’s No Other Choice

It’s easy to give up EV for peace of mind when you get 100% cashback up to $1,000. It’s much harder when it’s 10 or 15%. Or when the bonus comes with a 70x or 100x wagering requirement. Playing it safe doesn’t work here. The wagering just eats the whole bonus. So you either skip the bonus or go all in to clear it.

One of the craziest ways I’ve ever cleared a bonus went like this. I got a 100% bonus up to €200. So I could deposit €200 and get €200 in bonus money. By then they had changed the bonus terms so you could only play slots.

I ended up betting €400 on a single spin. I’m planning to break down the math behind bonuses like this in a separate post.

It ended with me hitting the bonus round and winning €40k. After that, they wouldn’t let me play on that site anymore. I’m planning a separate post about that too, so I don’t overload this one.

TL;DR

In the end, everyone picks what works for them. The smartest way to start is to play it as safe as possible. Taking on extra risk for extra EV makes sense once you have a bankroll and a solid grasp of how to manage it and how variance works.

That’s what I did too. To get my first bonuses I had to wager my deposit 3 times5. And at the very start, I did that wagering with low risk bets on red, black and zero. I only switched to max bets once I had enough bankroll. But not enough understanding of the risks.

So sometimes the “absurd” $1,000 on a single number is actually the most rational bet.

I need your honest opinion.

To be honest, this experiment was inspired by John Reeder and his Risk of Ruin Premium newsletter. He started making animated visuals for his podcast episodes, and the result was, in my opinion, absolutely stunning. So I wanted to see what my own posts could look like in that format. The difference is that I don’t have a podcast, so on top of the animation I had to generate the voices too.

So I used every bit of modern tech I could get my hands on and turned my post “Are Slots Really Random? How RNG Works” into a 5-minute video, with AI voices and AI-made visuals and animation.

Honestly, I like how it turned out, but I’m probably not the most objective judge here. So what do you think: does this have a right to exist, or is it a complete disaster? 😅

There’s also an extended audio version (about 20 minutes) that goes into maximum detail: how the RNG actually picks numbers, why “hot” slots don’t exist, what RTP really means, and where you can still find a real edge.

🎧 Extended audio — 21 min

So here’s my question: does this have a right to exist, or is it a complete disaster? 😅

Would you watch or listen to future posts in this format, or maybe even older ones? Or do you prefer just reading? Even a one-word reply helps: “more”, “meh” or “stop”. And if you have specific feedback (too long, the voices, the visuals, anything at all), I’d love to hear it. Just hit reply or leave a comment.

Thanks for reading, and hopefully for watching too!

Does the jackpot ever hit break-even?

Grand Spinn survives to the break-even point in 6.6% of cases, roughly every 15th jackpot.

Why so rare? How often a jackpot reaches break-even depends on what share of each bet goes into the pot. The bigger the share, the more often it gets there. The smaller the share, the less often. Make it too small and it never gets there at all.

Where the contribution goes

In Grand Spinn the 2.7% contribution is split between the current jackpot and the next one, 2.16% and 0.54%. That split affects how often the jackpot reaches break-even, like this.

For maximum EV you want the whole contribution to go into the current jackpot. First, more jackpots reach break-even. That makes sense, for the same amount of betting the pot grows by more. Second, it raises the EV of playing the jackpot, because everything your bets put in comes back to you along with the win. With a baby jackpot, part of your bets goes into the next pot, which may never reach break-even, and you may never get to play it.

One more interesting point. If the whole contribution went into the next jackpot, which I have never seen in practice and which makes zero sense from a marketing or excitement point of view, the jackpot would reach break-even just as often. But then it would be a true break-even point that always stays at the same level.

How big the contribution is

But even if 100% of the contribution goes into the current jackpot, the jackpot can still be a dead end if the contribution itself is small. In this case, if the contribution were 1%, the jackpot would reach break-even once in 120, even though the break-even point itself would drop from 114k to 85k1. And the EV of playing it would fall almost threefold.

The other way round, at 10% every fourth jackpot would be positive, but the break-even point would fly up to 236k, and the EV would be at its maximum. Most players would be playing at 86% RTP, just so a jackpot hunter or a syndicate can turn up at the end and take the pot.

Nobody plays it, nobody wins it

And even if a slot has a high jackpot contribution, all of it going into the current pot, plus a high base RTP, the jackpot can still be worthless if nobody plays it!

So the game has to be popular. If nobody plays it, it does not matter how good the math is, it will never be +EV. Take Playtech’s jackpots. They used to be very popular, and now the patient is more dead than alive. Same with 888’s exclusive jackpots, which, judging by how slowly they grow, almost nobody plays. So you need at least a rough estimate of how many +EV jackpots you can expect in a year.

To be fair, Grand Spinn is not the best example, either in how often it hits 100% RTP or in how popular it is. Mega Joker, for example, is positive more often than every fourth time, its base RTP and jackpot contribution are higher, and more people play it.

I have played only 2 positive Grand Spinns, around fifty Divine Fortunes and more than one hundred Mega Jokers. And Red Tiger's network jackpots drop even more often than that. Each of these deserves its own post. I deliberately did not start with the most popular one.

This is that post. Full method, then a real slot worked end to end.

Why timing is the whole game

In most casino games nothing carries over. Whatever happened before you got there does not matter, and whatever you do will not matter to whoever sits down after you.

In some games it works differently. Their state changes over time, and the return to the player goes up or down. Sit down at a bad moment and you are playing below the advertised RTP. Sit down at a good one and you can be over 100.

These are games with persistent state.

Blackjack is the classic example. Every card that leaves the deck changes the state of the deck, and each rank moves it by a different amount. Strip every five out of the deck and players will line up around the block. Strip every ace and the line disappears.

Accumulator slots work the same way. Playing Buffalo Link when one buffalo remains out of 1,600 to trigger the bonus is a completely different game from playing when you still need a thousand. Buffalo Ascension does it with the reels. Playing it when they have grown all the way up is a completely different game from playing it when they are at the minimum.

Progressive jackpots follow the same logic. Playing when the pot has reached half a million is a completely different game from playing when it sits at 20,000. You can be playing with 93% RTP or 103% RTP — the difference is massive.

There's one more game where RTP can swing from 50% all the way to 150% and higher. I'm not laying all my cards on the table right now though — that's a story for several separate posts.

To get a real edge in progressive jackpots, you need four things:

1. Find the break-even point, the jackpot value at which the house edge goes to zero.

2. Only play above that point.

3. Have a bankroll big enough to keep risk of ruin low.

4. Play systematically and put through as much volume as you can.

Finding the break-even point

You need four numbers: how often the jackpot drops, how much of each bet feeds the pot, the RTP of the base game with the jackpot stripped out, and the seed value.

Jackpot frequency is the hard one, and it is the one you cannot work around. Three ways to get it.

1. Read the provider’s documentation. Some studios publish it. NetEnt and Yggdrasil, for example. It is rarely sitting in plain sight, but it can be found.

Easiest route when it works. In a fair world every provider would publish its jackpot mechanics for the sake of transparency. In the real world that same information hands advantage players an edge, though I doubt the studios lose much sleep over that particular consequence. They hide everything by default.

2. Work it out yourself. A bit harder, and it only works when the jackpot is tied to one specific, definable event. A royal flush in Caribbean Stud, five identical numbers in a row on roulette, five cherries on line 5, ten winning spins back to back, and so on.

Caribbean Stud is easy once you have the paytable. It's not that hard to calculate in Google Sheets1, especially these days with LLMs becoming so common. I spotted a +EV situation in Caribbean Stud twice. The first time I didn't have the bankroll for it. The second time I didn't have the opportunity.

Roulette is easier still, everyone knows the hit rate of a single number, you just multiply the probabilities. Slots take more work. You need a few hundred spins to estimate hit frequency, or the frequency of a cherry on line five, and at that point you may as well go back to option one and hunt for the documentation.

3. Collect data on real jackpot drops.

Slowest and most painful. You log drops until the average settles down, then work backwards to frequency.

The problem is how slowly it settles. With 95% confidence, and assuming drops are memoryless, the error on your average runs at roughly two divided by the square root of your sample. Which sounds abstract until you convert it into the number you actually care about.

Break-even scales one to one with frequency, so the error carries straight through. Say your calculation lands on a break-even of €100,000. Here is how much you can trust that number:

At 100 drops your entry point has a €40,000 window in it. You either start way too early and burn money, or way too late and hand the spots to competitors.

This only works for jackpots that drop several times a day. Usually that means global pots like Red Tiger, where one jackpot is shared across a large group of casinos. Or a local pot at a very large casino, like the one in Michigan that got farmed for a long stretch by players who read this blog. I wish I could write that. They worked it out on their own. Still, the example holds up. You gather the data, you calculate the break-even point, you get your edge, and then you get your account closed, exactly like they did.

So, most progressives have a jackpot value above which their RTP passes 100.

To find it you need the jackpot frequency, or the average value the pot drops at, which gives you the same thing.

Break-even = (1 − base RTP) × turnover per jackpot

Now to the real examples, and to why the best moment to sit down is not always the break-even point.

Some slots with multi-million jackpots really do have a base RTP (excluding the jackpot) below 90%, for example Hall of Gods and Mega Fortune. But there are others that are far more pleasant to play.1

Mega Joker, my favorite

Mega Joker has a 99% RTP, 96% of which comes from the base game and 3% from the progressive jackpot. The jackpot here is far easier to hit than the max win on most regular slots.

• At a €1 stake, the odds of hitting the jackpot are 1 in 500,000

• Jackpot values range from €2,000 to €20,000 and up2, which translates to wins of 2,000x to 20,000x

For comparison:

• x15,000 on Gates of Olympus 1000: 1 in 2,749,771

• x15,000 on the new Big Dog House: 1 in 17,953,321 on average

This slot never runs a “watered down” RTP version. You can always be sure you’re playing with the best possible odds. And if you only play when the jackpot exceeds 20,000, the slot’s RTP hits 100%, though we’ll come back to that.

To be fair, there are downsides too. First, you need to play with optimal strategy: betting the right size in the supermeter and cashing out at the right time. Play it without optimal strategy and you can end up with an RTP as low as 85%.

This makes the game more volatile, since you never get small wins below 160x. Even so, it’s comparable to regular slots: SD 13.21 versus SD 13.0 for the classic Dog House

That said, this is a very specific game. You have to make a decision on every single spin, so you can’t just set it to autoplay and walk away. On top of that, the 2003-era graphics might feel dull to a lot of players today.

For one, I rarely play without an edge, and when I do have an edge, I have people who play for me. Grinding a $10 max bet without an autoclicker for several days straight is not exactly my idea of fun.

Divine Fortune

Another popular NetEnt slot is Divine Fortune, which has personally brought me no shortage of pain, suffering, and profit. The return to player here is almost 2.5% lower than Mega Joker, though still within the normal range for the market. If anything, Mega Joker was the outlier, not this one.

96.59% RTP, of which 4.07% of the base RTP goes to the jackpot. The odds of winning here are tougher, but the wins themselves are bigger and more realistic than a lot of max wins on regular slots. Judge for yourself.

The odds of hitting the jackpot are 1 in 2,686,500 at a 1 euro stake, which is still better than the odds of landing 15,000x on Gates of Olympus.

Even compared against DOA 2, the benchmark slot for big multiplier wins, the numbers hold up. DOA 2's 111,111x hits at a frequency of 1 in 44M5. Divine Fortune's jackpot, playing at 20 cents a spin, hits at 1 in 13.4M, which for a 143,374 jackpot, as shown on the screenshot, is equivalent to a 716,870x win, or a 100,000x win for a 20,000 jackpot, the size the jackpot lands at in 90.4% of cases.

There's also Mercy of the Gods, which is almost an exact copy of Divine Fortune, and Vegas Nights, which has close to double the jackpot odds of Mega Joker, with jackpot sizes in a similar range.

Hard Rock Bet’s online casino rules say every bet has an equal chance of winning. But in one of its jackpots, that’s apparently not true.

It’s the equivalent of matching all six Powerball numbers and walking away with nothing because the jackpot hadn’t reached some threshold, say a billion dollars. Sounds absurd. But something very similar appears to be happening right now at Hard Rock Bet.

In March 2026, a player in Michigan noticed that one of Hard Rock Bet's four progressive jackpots, the Mini, almost never paid out below $337, and started betting only once the jackpot got close to that number. He says doing this earned him roughly $125 an hour. Some time later, Hard Rock Bet froze his account, his wife’s account, and the accounts of other players who’d been playing the same jackpot. Across the players he knows about, total winnings came to roughly $800,000, about $300,000 of which remains frozen. The regulator he complained to wrote back with a letter whose gist was: we can’t help you, and we won’t.

That player, a subscriber to the blog casinoshatewinners, gave me more than 20,000 records of Mini jackpot payouts. Going through them, I found that the actual distribution of wins doesn't square with what the casino's own rules promise.

Hard Rock Bet's official rules state:

“Jackpots are awarded randomly. All players have an equal chance of winning with each wager they place on an eligible game while they are opted in.”

Here's how I got there, and what I think it means.

How Progressive Jackpots Work

When a casino claims that anyone can win and any bet can be a winner, this is usually understood literally. Any player can win on any bet at any jackpot value.

Most jackpots are actually structured quite simply. There’s a starting amount below which the jackpot cannot drop after a draw. With each bet, a fixed percentage (typically 1–5%) goes into the jackpot fund—this is called the jackpot contribution. Part of this percentage is set aside separately for the next cycle, known as the reserve or baby jackpot contribution, which becomes the future starting amount.

Most importantly: there is a fixed probability of winning the jackpot on each specific bet. For example, 1 in 50,0001. This means that on average, one jackpot is won for every 50,000 bets placed—just as a specific number on European roulette comes up roughly once in 37 spins, or a winning lottery combination comes up roughly once in several hundred million tickets. You could win on your first attempt, or you might not win even after hundreds of tries.2

A progressive jackpot with fixed probability should behave similarly: the specific winning amount is unpredictable. This is exactly how the rules say a jackpot is supposed to work. Hard Rock Bet's own terms, in section 8, state that “jackpot winners are determined randomly by an independent random number generator and not the result of any specific outcome from the Eligible Game's gameplay.”

There are also jackpots with 'must-hit-by' mechanics. These are jackpots that must be awarded before reaching a specific threshold or time limit. For example, before hitting $10,000, $1,000,000, or by 11:00 PM. In those, timing is everything: the closer the jackpot gets to its target, the higher the odds of it hitting, and that mechanic is disclosed upfront.

The Mini jackpot is not described as one of these.

Impossible to Lose

The player who shared this story first noticed something strange about the jackpot feature in February.

"I discovered it in early March and shared it with a few folks right away," he said. "It was not complicated to discover that it was +EV once you noticed that the jackpots hit so closely together all the time." None of this required coordination — the logic was simple enough that strangers he'd never met kept landing on it independently, using nothing but the jackpot amount that's visible to anyone before placing a bet. Over time, he says, watching those unfamiliar players win repeatedly — then "never win again, almost certainly suspended by the site" — made clear that others had found the pattern too.

After that, he started playing the jackpot directly. The Minis almost always hit in the 300s, he says, topping out around $421 — and each 10-cent contribution puts 31% into the current pool. "So as long as you are playing for less than 31% of the 'life cycle' of a Mini, you know you are profitable," he said. "Starting at something like $335, you will never play for anywhere near 31% of the cycle before it hits."

Expectation vs. Reality, in Two Charts

Over the full observation period, the player collected just over 20,000 Mini jackpot data points, raw and unfiltered by his account, with only a handful of missing entries.

Average: $357.70. Median: $358.48. Range: $278.86–$421.62. And 95% of all wins fell inside a $326–$383 corridor, just $57 wide.

To show how atypical that is for a jackpot where every single bet has a shot at winning, I ran a Monte Carlo simulation with a fixed trigger probability on each bet, using the same sample size (20,458 hits), the same average ($358), and the same splits: a 31% jackpot contribution and a 13% reserve contribution.

It should be exponential: a peak at the lower bound, then a smooth decline. Instead, it’s a bell, packed into the middle of the range.

It should be widely spread: the simulation ranges from $7 to $3,296. Instead, there’s a narrow corridor of $278.86 to $421.62.

There should be a long tail: rare, but large payouts. Instead, there’s a hard ceiling. Not once across 20,458 hits did the payout move outside that corridor.

There should be a gap between the mean and the median: a long tail of rare, large payouts pulls the mean up while the median stays lower (in the simulation: mean $356, median $288). Instead, Hard Rock Bet’s mean and median are nearly identical: $357.70 and $358.48. That’s the signature of a ceiling, not an open tail. If large payouts were possible even occasionally, they’d pull the mean upward the way they do in the simulation. Here, they don’t.

And the most telling part: the frequency of wins should rise and fall gradually. Instead, there’s a sharp break at two specific points. Below $340, wins are eight times rarer. Above $380, they’re ten times rarer.

A break that sharp, at two specific points, is statistically impossible for a distribution that rises and falls naturally. It looks much more like a hard condition built into the jackpot’s own payout logic, as if the odds of winning were sharply suppressed below a certain amount and sharply boosted above it. That’s how “must-hit-by” jackpots typically work, where the odds of a payout deliberately climb as the amount nears a target threshold. Nothing like that is mentioned anywhere in Hard Rock Bet’s rules for the Mini jackpot.

This isn't just a theoretical model on paper. The same shape shows up in real, non-simulated data too. Here's an actual jackpot from the provider Red Tiger, where every bet has the same odds of winning, with data collected at a different casino: 2,056 real hits.

The shape closely matches the simulation: a peak near the lower bound, a smooth decline, and a long, rare tail stretching to $138,649. And the same gap between mean and median seen in the simulation: an average of $15,377 against a median of $9,613, with rare, large payouts pulling the mean upward while the median stays far lower. This is what an honest, fixed-probability jackpot actually looks like — not a hypothetical, but a real one, drawn from real payout records.

Hard Rock Bet’s Mini jackpot matches none of it. The conclusion is hard to avoid: it is statistically impossible for the jackpot to comply with the rules advertised on the website.

The Rules Say One Thing, the Numbers Say Another

Hard Rock Bet's rules claim that the jackpot is random and that every bet has an equal chance of winning. But 95% of all payouts fall inside a $326–$383 corridor, and wins drop sharply below $340. A bet placed well below that point had, in practice, far worse odds than the rules describe, no matter how many times it was repeated.

So the jackpots are random only in the sense that the results don’t depend on past values. The distribution of values isn’t random. It’s shaped by something specific.

That’s not the same as deception. A controlled algorithm isn’t automatically a euphemism for it; must-hit-by jackpots are controlled too, and they’re advertised as such. The problem here is narrower: the pattern in the data doesn’t match the pattern in the rules.

Besides that, there’s another strange thing about this jackpot.

The rules state: “If there are insufficient funds in the Reserve to meet the reset value, Hard Rock Bet will fund the difference to ensure each jackpot reset value is met.” The same rules also state that the jackpot starts at $7.

So according to the rules, the starting value should be $7 even if there isn’t enough money in the reserve, but what happens if there’s a surplus of money isn’t specified anywhere.

Usually in such cases all that money also rolls into the fund for the next jackpot (standard practice for many jackpots). The rules also specify how each bet is split: 31% of the jackpot contribution goes into the current Mini pool, and 13% goes into the mini reserve.

If you apply these official percentages to the actual average win of $357.70, the starting value should come out at around $357.70 / 31% × 13% = $150. However, according to a subscriber’s observations, the actual starting value hovered around $90.

There's no must-hit-by language anywhere in the Mini/Minor/Major/Mega rules, either — instead, they promise an equal chance on every bet. And in the general educational section about progressive jackpots on the same site it says: “No strategy or skill can influence when they hit.” If the data I’m working through in this piece is correct, for the Mini jackpot that is, to put it mildly, not quite the case.

The player pays an extra 10 cents on top of every bet specifically to take part in the jackpot. If bets below $337 are structurally unable to win, then the RTP (return to player) in that range is apparently zero, the player is paying for a chance that, if the data holds up, simply doesn’t exist in that zone.

Win the Jackpot, Get Banned

The irony of this story is that its hero isn’t a victim of the casino in the usual sense, but a player who beat the system using its own rules. He didn’t break anything, didn’t register fake accounts, and was punished for it anyway:

“I stopped because my account, my wife’s account, and later on, the accounts of dozens of other people, all got suspended. Hard Rock accuses us of no wrongdoing but has locked our funds/accounts and now ghosts us completely. One person who won a Mega Jackpot back in March has still not been paid for it despite doing nothing wrong.”

Support's reply was the standard one: the account had been suspended "for your protection," pending a review that would restrict access in the meantime.

By the player's account, this pattern repeats: players are now getting suspended within 48 hours of starting to play the Mini jackpot strategically. Accounts aren't closed outright. They're suspended indefinitely. As he put it, "they would have to pay out your final balance to close your accounts, and they don't want to do that."

The casino bans players who win by playing the jackpot, doesn’t bring any accusations against them, and, most surprisingly, doesn’t remove a jackpot that doesn’t match what’s stated in the rules, doesn’t change the rules, and doesn’t publish any statements.

The player filed a complaint with the Michigan Gaming Control Board. On May 6, 2026, a response arrived whose essence can be boiled down to one sentence: the complaint review process doesn’t exist to return money to the player or to inform them of the review’s results.

“...its purpose is not to provide you with: (1) an administrative remedy to obtain money or any other form of legal or equitable relief from a licensee... or (2) information on the Board’s review of, and findings regarding, your... complaint... you should not expect to receive further correspondence or updates from the Board regarding this... complaint.”

In other words: the regulator can (in theory) penalize the casino as a licensee, but the player who filed the complaint will never be told about it, and it won’t get him his money back.

Conclusions

In my view, and I'm firmly convinced of this, mistakes happen anywhere people are involved.

Is a mistake like this worth regulatory attention? I think so, because as it stands, the gap between the stated rules and the actual odds misleads players. When you buy a lottery ticket, you expect every ticket to carry the same odds — not that some tickets, by design, never had a chance to begin with because they were bought at the “wrong” moment, while others never had a chance to lose.

In a private message, the player told me a Mega jackpot in Michigan was about to go off, climbing toward six figures. He was right. It hit shortly after, at $225,413.77. Hard Rock Bet's own website backs that up.

Whatever turns out to be happening here, in a genuinely random jackpot, nobody should know in advance when it’s about to go off.

13 Aug. 2026, final update : Players received their funds. The jackpot is still +EV.

This whole story is a great example of massive +EV in slots, uncovered through analytics and math. One of those cases where the edge was there for anyone to take.

In land-based casinos, this could be a biased wheel that makes certain numbers hit more frequently, or a device that predicts where the ball will land.

When I was playing poker professionally, I had one constant wish: more fish at the table. Weak players, recreational gamblers, people who just wanted to have fun.

I have two accounts on prediction markets. The first one is purely degenerate. I occasionally throw money at sports, esports, and politics just for fun. There’s probably no real edge there, which is why I do it rarely.

The second account is different. I'm running a hypothesis there: small bets first, scale up if it works. A bot handles all the trades, exclusively on sports events. The logic is dead simple — so simple I suspect a lot of sports bettors are doing the same thing. I'll write about it properly once the experiment reaches a conclusion. For now, here are the interim numbers: nearly 3,000 predictions, ~1% ROI.

I also had another hunch: bets with 90%+ implied probability should carry a small structural edge, because people chasing big multipliers are on the other side. Turns out this hunch has evidence behind it.

Spoiler: the gap between the best and worst position is 64 percentage points. More on that below.
