Keno is a popular lottery-style game that originated in China and has since been adapted for play in other countries. It is a game of chance where players choose up to 10 numbers from a total of 80. The winner is determined when the house randomly selects 20 numbers out of the 80.
The object of the game is to correctly select as many numbers as possible out of the 20 that are randomly drawn. Players are awarded prizes depending on the number of correct selections they make, with the largest prizes awarded for correctly selecting all 10 numbers.
