02The game
How it plays, and where it fits.
The game
- What the player does
- The player marks 1 to 10 of 40 numbers and picks a low, classic or high risk table; 10 balls are drawn and the payout follows the number of hits.
- Why players come back
- Keno sized for a phone: 40 numbers that stay full-size tap targets, three risk tables for every count of numbers, and every draw checkable from its seeds inside the game.
- Round structure
- Single decision. Mark 1 to 10 numbers and a risk, then one draw of ten balls settles.
- Session fit
- Quick sessions: a draw takes under 3 seconds. Single player. Suits auto play.
- Stakes in this build
- 0.10 to 100 demo credits. 0.10 to 100.00 per draw.

40 numbers, 10 balls drawn, every one of the 847,660,528 possible draws equally likely. Each table's return is its exact hypergeometric sum, and all 30 tables return between 97.16% and 97.90%. No table has a 1.00× entry, so a round wins, returns part of the stake, or loses. The most any round pays is 10,000×: high risk with 8, 9 or 10 numbers marked and every one hit.
Pace
2.6 s a round, about 1,369 rounds an hour. Measured in Chrome with every control pressed as soon as it was enabled, so this is a ceiling with no thinking time.
GGR / 1,000 rounds is the theoretical gross gaming revenue from 1,000 rounds at a total stake of 1.00: house edge × 1,000. Volatility is the standard deviation of one round’s total return per 1.00 of total stake. Low under 1.5, Medium 1.5 to under 5, High 5 to under 15, Very high 15 and over. For scale: an even-money roulette bet is 1.00, a straight-up number 5.84.
