Casino rulesKeno — rules
How Keno plays in OmertaEra, the free Prohibition-era mafia MMO. The same rules are shown where the game is played, and every outcome is provably fair.
Mark 1 to 10 different numbers from 1 to 80 and set a stake. One draw for the whole lounge: 20 balls every 45 seconds, and tickets close 35 seconds after the draw opens. A ticket is paid on the table for the number of spots it marked, and only that table; pays include your stake. One ticket per player per draw.
