Golf (also known as Polish Polka, Polish Poker, Turtle, Hara Kiri and Crazy Nines[1]) is a card game where players try to earn the lowest number of points (as in golf, the sport) over the course of nine deals (or "holes").

Beginning at the dealer's left, players take turns drawing single cards from either the stock or discard piles.

A full game is typically nine "holes" (hands), after which the player with the lowest total score is designated the winner.

Golf can be played so that instead of ending the game automatically, a player must choose to "knock" instead of taking their turn.
