Keno is a Las Vegas style game in which a player has a screen of 80 numbers and you can pick as many numbers as you wish, as a example I pick 2 numbers. Then the machine picks 20 of the 80 numberss on the screen and if your numbers are part of the 20 numbers picked, you win xxx tokens. Another example if you pick 5 numbers and 3 of them come up you would win a portion of chip prize, or the same as a State Lottery. HTH
