Keno: picking the right number of numbers

You pick 1–10 numbers from 40. Ten are drawn. Your payout depends on the (picks, hits) pair. Every row pays 99% RTP in the long run — but the shape of each row is completely different.

Fewer picks = more hits, smaller pays

At 1 pick you hit 25% of the time and pay 3.96×. At 10 picks you hit 5+ matches ~4.2% of the time and pay 14.45× at the threshold, scaling geometrically up to 3511× for a 10/10.

Low pick counts feel like dice — small, frequent. High pick counts feel like lottery — rare, massive.

Risk tiers

The Classic / Low / Medium / High switch changes the threshold (how many hits to start paying) and the growth factor. Higher risk = rarer but bigger hits.
