The Roulette Jackpot That Shouldn't Have Existed
Regular readers of this blog already know that Martingale, D’Alembert, and similar systems simply cannot work by design. To gain a real edge, you need specific conditions that actually create that edge.
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.
To make money in roulette, all you need to do is rule out two numbers. With two numbers eliminated, the odds became slightly better than even, flipping the house’s slender advantage.
Online, the edge can come from bonuses or cashback offers that flip the math in your favor. Or from promotions that temporarily make the game profitable. I’ve written before about how I won around $40k betting a dollar on a single number — the promo paid $100 and $1000 when lucky 7 landed two or three times in a row. That made it an extremely +EV spot.
The Reddit Post
I was scrolling Reddit recently and came across a post titled “I broke roulette and caused my casino to remove a specific game.” I opened it half-expecting the usual nonsense — but it turned out to be genuinely interesting.
The author described a progressive jackpot roulette table at a land-based casino. For context — online players might remember Royal Roulette by Microgaming, which had a progressive jackpot too, but required hitting the same number five times in a row. The break-even point there was somewhere around $811,000. Even if the jackpot reached that threshold, you'd need a bankroll well over a million dollars to actually realize that edge, which is easier said than done.
This story was far simpler.
The jackpot was tied to a single pre-selected secret number. That number stayed fixed every spin until it hit. The jackpot started at 2,000 units and grew by 0.5 per losing spin, capping around 5,000. Nobody knew which number it was until it landed.
To qualify:
Bet on one number only
Minimum bet: 10 units (the author used "units" instead of his local currency — the exact amount isn't important for the math)
You must have the highest bet on that number at the table — if someone bets more and it hits, they take the jackpot and you get nothing
The Math
The math here is surprisingly straightforward. The jackpot lands on average every 1,369 spins — and at 10 units per spin, your net loss before hitting it is just 370 units (1,369 spins х 10 units х house edge of 1/37). Since the jackpot starts at 2,000 units, it’s +EV by default.
The real complication is the highest-bet rule. To guarantee you collect the jackpot, you either need to be betting the table maximum or be confident you’re essentially alone at the table. At a bet of 100 units, for example, the jackpot needs to exceed roughly 3,690 units before it becomes worth playing.
I’ve seen similar roulette setups in land-based casinos before and walked right past them. A 2,000-unit jackpot never registered as a +EV opportunity. It will now.
What He Did
The author played solo for a while with no success, then recruited unemployed friends to cover more numbers and speed up the process. They hit the jackpot twice and collected. On the third attempt, the casino investigated, interrogated the group, and initially refused to pay. The gaming commission got involved and ruled in their favor — no cheating, just a loophole. They got paid. The game was removed.
It was not a life-changing amount — 10,000 units came to around $3,000 — but I feel damn proud of having beaten the house without cheating.
The Missing Pieces
A few things he never explained:
How did he actually confirm the jackpot worked this way? Did he ask staff, read the rules, or just assume?
How did he handle the highest-bet rule with strangers at the table? At a minimum bet of 10, anyone could theoretically outbid him on the jackpot number and take it
And perhaps most importantly — where does one find that many unemployed friends available at 4am on a weekday?
My best guess is he simply assumed nobody else was betting straight up regularly — which in a quiet local casino at 4am is probably a fair assumption. It’s also possible he was playing slightly -EV and got lucky — and the casino’s reaction was just managers overreacting to a systematic-looking pattern.
Either way, the lesson is straightforward: finding an edge requires staying alert and being ready to act when the opportunity shows up.
So — mathematical edge or just a guy who got lucky twice and wrote a Reddit post about it?
