How to play Keno

  1. Choose Keno in the demo arcade and enter a wager between 0.01 and 1,000 demo credits.
  2. Pick exactly five different numbers from the 1–40 grid. Tap a selected number again to swap it out.
  3. Press Draw Keno. The server draws ten distinct numbers from 1 to 40 and counts how many of your five picks were drawn. Your hits are highlighted in the drawn-numbers row.
  4. The paytable below the grid shows what each hit count pays. Zero or one hit loses the wager.

Keno payouts and multipliers

Payouts by number of hits, with the chance of each result:

5 hits (about 0.04%)200×
4 hits (about 0.96%)16×
3 hits (about 7.9%)4×
2 hits (about 27.8%)1.5×
0–1 hits (about 63.3%)0×

House edge

Weighting each payout by its probability gives an expected return of about 96.4%, a house edge of about 3.6%. Most of that return comes from frequent two- and three-hit results; the 200× jackpot is rare.

Base wallets and demo credits

You can play every round as a guest. Sign in with an EVM wallet on Base or BNB Smart Chain (BSC) and each round also earns ROLL points for the leaderboard. Signing in only asks your wallet to sign a message; it never sends a transaction. Ethereum mainnet and Robinhood Chain sign-in are coming soon.

Demo credits only. Credits have no cash value and cannot be bought, deposited, withdrawn or exchanged. Results are server-generated simulations, not a provably fair protocol. See how it works and the FAQ.
