full game is typically nine "holes" (hands), after which the player with the lowest total score is designated the winner. A longer game can be played to eighteen holes. Variations There is a multitude of variants in multiplayer golf. Some common ones include: Single-deck golf For two to four players. Rules are the same as in double-deck golf. Sometimes, jokers are not used. Knocking Golf can be played so that instead of ending the game automatically, a player must choose to "knock" instead of taking their turn. Remaining players then have one turn to draw a card to improve their hands and then scores are totaled and recorded on a running score sheet. This rule is more common for four-card golf. Four-card golf Suitable for 3-7 players, in four-card Golf each player receives four cards face down in a 2×2 grid and reveal two before play begins. Play proceeds similar to six-card golf. The end of a round is initiated by a player `knocking', after which other players get one final turn. Nine-card golf One or two decks are involved, depending on the number of players. One deck is adequate for 1-3 players, two or more decks are suggested for 4+ players. To begin the game, each player is dealt nine cards, laying out the cards face down in a 3x3 grid. The method or pattern for how the players layout their 3x3 grid is arbitrary, as long as the cards remain face down. The game is played as six-card golf. Once any grid contains only face-up cards, the game is immediately ended, there are no further turns, and all players must flip all their face-down cards to determine their scores. Scoring is the same as six-card golf, with players having to form a full three-of-a-kind column to have that column score zero. This process of game play continues for nine total games or until a player exceeds 50 points. Optional rules of this version include: Horizontal and diagonal lines of three also score zero Playing with jokers in the game, valued at -4 points Every pair of adjacent (horizontal or vertical) equal cards scores zero If the player places four cards in a square pattern (i.e. 2x2 block) of the same face-point value, this results in a negative score (e.g. -25), for those four cards Instead of drawing a card, a player may choose to flip a card in
