How Keno works

Choose how many numbers to play (1–10) and which numbers from the 80-cell grid. Place stake. The system draws 20 numbers. Payout depends on the pick-count and how many of yours hit. With 10 picks, hitting 5 of 20 pays ~3×; hitting 10 of 20 pays a jackpot multiplier of ~10,000×. Pay-tables are published in-game.

Strategy & bankroll

RTP is constant at 99% across every pick-count configuration, what changes is variance. Picking 1 number is a near-50/50 (1.4× return on 25% hit rate). Picking 10 numbers is a long-shot lottery (10,000× on a ~1 in 8.9 million hit). Auto mode is essential for hitting enough rounds to converge on the 99% return; one 10-pick session can run hundreds of rounds without a payout.

Verifying a Keno round

The 20 drawn numbers are a deterministic function of the seed pair and nonce, mapped through a Fisher-Yates shuffle of the 80-position pool. Reproduce the shuffle, take the first 20 positions, confirm they match the casino's published draw.

FAQ snapshot

Are there 'lucky' numbers?

No. Every number has identical probability of being drawn (20/80 = 25%) and the draws are independent across rounds. Patterns and hot/cold tracking are pure superstition.

Why does picking more numbers reduce my hit rate?

It does not, the chance of hitting at least one increases with more picks. What changes is the chance of hitting all of them: catching 10 of 10 is much rarer than catching 1 of 1.

What is the highest multiplier?

10,000× on 10-pick + 10 catch. Probability is ~1 in 8.9 million, most 10-pick rounds end with 0–4 catches and no payout.

Can I pick the same number twice?

No, each number can only be selected once per round. Use auto mode to play the same selection across many rounds in a row.
