Keno

Each player marks a chosen set of numbers, commonly between one and twenty, on a blank keno ticket.

The ticket is submitted along with a wager before the numbers are drawn.

A set of numbered balls, typically twenty out of eighty, is drawn randomly using a machine or ball cage.

Players compare the drawn numbers against the numbers they marked on their ticket.

Payouts are determined by how many of the player's chosen numbers matched the drawn numbers.

Winning tickets are paid according to a posted payout table before the next round of numbers is drawn.
