Most casino jackpots are a mystery. There’s a big number on the screen that keeps climbing, some light flash and every so often someone wins it.
Ours aren’t like that. The rules are public, you can check the maths yourself, and every dice bet you place already shows how close it came. Here’s how it all works.
Three games, two kinds of jackpot
Dice, Roulette and Slots all have jackpots, but they don’t all work the same way.
Slots is the simple one. Line up 77777 and you win 1,000x your base bet, every time. The Rewards page shows exactly what that’s worth: change the amount in the bet box and the payouts update in the rewards tab as you type, so you know what 77777 would pay before you spin.
Dice and Roulette share a progressive jackpot, a pot that keeps growing until someone wins it. CryptoGames fund it entirely, so nothing is taken from anyone’s bets to build it up. You can see the current total on the Jackpots tab.
The progressive jackpot takes more than a lucky roll, though. The bet itself has to qualify, and that’s the part most people miss.
The dice jackpot
A dice bet wins the progressive jackpot when all three of these are true:
- The roll lands on exactly 7.777 or 77.777, and it’s a winning roll
- The jackpot number is 77
- Both the bet amount and the profit meet the minimum for your coin
The roll
Dice results run from 0 to 99.999, which gives 100,000 possible outcomes, and two of them are jackpot rolls. Landing on one isn’t enough, though. It has to be a winning roll, so your target has to include it.
Bet under 80 and both 7.777 and 77.777 count as wins. Bet over 50 and only 77.777 does. Bet under 5 and neither does, so you’re out of the jackpot before the dice even roll.
The jackpot number
Plenty of players have never spotted this one. Every dice bet gets a jackpot number between 0 and 99, worked out from your server seed and client seed combined and run through SHA-512. Click any bet ID and you’ll see it.
Here's an example:
About 838 SHIB on under 0.033, chasing a 3,018x payout. It rolled 46.408, so it lost, and the jackpot number was 36.
Even if that roll had come up 7.777 and the jackpot number had been 77, it still wouldn’t have paid out. Under 0.033 doesn’t cover 7.777, and 838 SHIB is nowhere near the minimum stake. That bet was never in the running.
The odds
A bet that covers both jackpot rolls has a 2 in 100,000 chance of the right roll. On top of that, there’s a 1 in 100 chance of the jackpot number being 77. Put them together and you get roughly one in five million per bet.
The odds don’t get any better the longer you play. Your millionth bet has exactly the same chance as your first, and the jackpot is never “due”. If you’ve read our post on the gambler’s fallacy, you’ll already know why.
The roulette jackpot
Roulette works the other way round. Instead of one very specific bet, you need a streak.
- The ball lands on 7 on four consecutive bets, all in the same cryptocurrency
- Each of those four bets is profitable, meaning you get back more than you staked
- The bet amount and profit on each one meet the minimum for your coin
The profit rule is the one that catches people out, because it applies to your whole bet, not just the chip on 7. Spread chips across half the table with 7 among them and the ball can land on 7 while you still get back less than you put down. That bet doesn’t count, and the streak ends there.
You can cover 7 lots of ways: straight up, red, odd, 1–18, the first dozen or the first column. Mix them however you like, as long as what comes back is more than what went down, on all four spins.
Our wheel has a single zero, so there are 37 pockets. Four 7s in a row works out at about one in 1.87 million.
How much of the pot you get
The jackpot scales with your win. Each coin has a win amount that unlocks 100% of the pot. On SHIB that’s 30,000,000. Win less and you get a proportional share, with a minimum of 1%, so a 3,000,000 SHIB win takes 10% of the pot.
On roulette, if your four winning bets were different sizes, your share is based on the smallest one. Three big bets and one small one means the small one sets the payout.
Check the requirements before you start
The minimum bet, the minimum profit and the full-jackpot amount are all set per coin. On SHIB the minimums are 7,500 for both the bet and the profit; on BTC it’s 150 sats.
Crypto prices move a lot, so those minimums aren’t always worth the same from one coin to the next. Before you chase anything, open the How to Play tab on Dice or Roulette and check the current requirements for your coin. Imagine rolling 77.777 with a jackpot number of 77, only to find your stake was 10 sats short.
Claiming it
You don’t! This is the best part - if a bet qualifies, the jackpot is credited to your account automatically. The system checks every bet against the rules, so you don’t need to report anything.
Is it worth chasing?
If you want a sensible way to make money, a jackpot isn’t it. But that’s not why anyone plays. Chasing a jackpot is fun precisely because it’s so unlikely. Every dice roll inside the right range is a tiny lottery ticket you didn’t have to buy separately, and every jackpot number that lands on 76 or 78 gives you that brief “ooh”. On roulette, two 7s in a row is enough to get your pulse going, even when you know the odds.
Some players make a game of it. They pick a coin, set a budget they’re happy to lose, and play their usual way with one eye on the jackpot number. Keep it to money you’d spend on a night out anyway, and treat any jackpot as a bonus rather than the goal. Then it’s just a bit of extra excitement on top of a game you were already enjoying. Next time you’re scrolling through your bet history, check the jackpot number. One day it might say 77.
