Keno is a number-picking game where you choose between one and ten numbers from a pool of forty, then the server draws ten numbers to see how many of yours match. It's built by Bethropic and offers four different risk levels—classic, low, medium, and high—each with its own payout structure. Players are drawn to it for the variety of ways to win and the chance to adjust their risk appetite across the board.

How it works
Pick your numbers, then the server draws ten from the pool of forty. What you are paid depends on how many of your picks came up and which risk level you chose.
The payout tables show that risk level dramatically changes what you're chasing. On high-risk play, you often get nothing for partial matches that would pay on classic or low, but when you do hit, the multipliers jump significantly higher. This means high-risk mode isn't just "the same thing but with bigger payouts"—it's a completely different game where you're betting heavily on either nailing more of your picks or getting nothing. Swapping between risk levels fundamentally reshapes which outcomes actually pay you money.

The odds behind it
- Hitting all ten of ten picks pays 1000× and comes up once in 847,660,528 rounds.
The return to player ranges from 98.7 to 99.1 percent depending on how many numbers you pick and which risk level you play. This means that across all your rounds, the game will pay back somewhere in that band, but the house keeps the rest. That return is built into every payout on every table, so no configuration tips the odds in your favor. The 1000× multiplier for hitting all ten numbers comes up roughly once every 847 million rounds, so it's the mathematical ceiling rather than something to plan around.
Fair by design
- Every round is provably fair: the outcome comes from a server seed, your client seed and a nonce, all shown with the round so you can check the result was fixed before the bet. You can rotate your seed at any time.
- A 0 bet is always allowed, so every original game can be played for free.
- Bet limits are set per coin rather than per game — the same minimum and maximum apply across the originals.

Payouts settle within the per-coin maximum profit cap, so the headline multiplier is the ceiling of the game, not of a single bet.
