How many numbers should you pick in Keno?
No number of picks changes the house margin much: at OpalRove every Keno ticket from 1 to 10 numbers returns between 93.59% and 94.35% over the long run. What changes is how often the ticket returns something and how big the top prize is. One number returns something on 25% of draws and pays 3.75 times the bet; ten numbers return something on about 11% of draws but can pay 10,000 times the bet.

So which should you choose?
Pick by the kind of result you enjoy, not by the return, because the returns are within a fraction of a percent of each other. Fewer numbers give steadier, smaller results; more numbers give long quiet runs with the chance of a large prize.
Whatever you pick, Keno returns about 94% of stakes over the long run. Set a budget before you play and use the deposit and session limits in your account.
