Keno is a lottery-style game that originated in China hundreds of years ago and found its way to Europe and North America. In its simplest form, players select spots on a card from numbers 1 to 80, and then the game "draws" those numbers for a winning card. If the numbers you draw match the numbers the card "draws," then you win. The amount of money a player can win depends on the amount of spots selected and the pay table of the game.
