How to play
Keno Rules
Pick 1–10 numbers from 1–40. 10 balls are drawn from the committed seed, and you are paid by how many of your picks hit, on the risk tier you chose.
How a round works
- Pick your numbers and a risk tier: Low, Medium, High, Expert, or Max.
- 10 balls are drawn from 1–40 by a seeded shuffle.
- Your payout is your stake × the multiplier for your pick count and hit count on your tier. Hit counts that pay nothing pay 0.
Every tier and pick count is calibrated by exact hypergeometric math to a 94.8%–95.3% long-run return. The tiers differ in shape, not in fairness: Low pays small and often (top 79x), Medium is the original table (top 47,710x), High swings bigger (top 11,222x), Expert is rare and large (top 169,832x), and Max is a lottery (top 10,000,000x, capped).
The live table: Medium tier
This is the table as it exists in the game code (the original table, kept byte-identical). The other tiers use the same draw with different multipliers.
