How Keno Works: Hypergeometric Odds, Risk and 99% RTP
Star Chart Keno still defaults to Practice for ordinary players, while a reviewed Keno V2 server-authoritative runtime exists behind the promotion gate. Pick 1–10 numbers from 1–40 and draw 10 without replacement; hit counts follow a hypergeometric distribution.

How to play
- 1Choose 1–10 numbers from 1–40.
- 2Choose Risk. Risk changes payout distribution, not draw probability.
- 3Bet triggers a crypto Fisher-Yates sample of 10 distinct numbers.
- 4The hit count selects the Practice multiplier used for payout and net.
Keno V2 canonical math
With p player picks and h hits, P(h)=C(p,h)×C(40-p,10-h)/C(40,10). The canonical Keno V2 paytable is risk-specific and its reviewed probability-weighted payout target is 99% RTP.
| Population | 40 | Draw 10 |
| Player picks | 1–10 | without replacement |
| RTP target | ΣP(h)M(h) | 99.00% |
Current fairness boundary
The public page can still run Practice, but Transaction Core already has a Keno V2 authoritative one-shot runtime with server HMAC-SHA256 distinct draws, Wallet/Ledger settlement and recovery. Public Wallet promotion remains locked.
FAQ
Do hot or cold numbers improve odds?
No in this model. Each round is a new sample without replacement and the labels have no advantage.
Does Risk change my chance of matching numbers?
No. Risk changes payout distribution only.
Why does the paytable depend on pick count?
Because the hypergeometric hit distribution changes with the number of player picks.
Is 99% the canonical Keno RTP?
Yes for the reviewed Keno V2 server target. Public Wallet promotion is not yet broad, so Practice remains the ordinary-player default.
