Four-ball billiards

Four-ball billiardsorfour-ball carom(often abbreviated to simplyfour-ball,and sometimes spelled4-ballorfourball) is acarom billiardsgame, played on apocketless tablewith fourbilliard balls,usually two red and two white, one of the latter with a spot to distinguish it (in some sets, one of the white balls is yellow instead of spotted). Each player is assigned one of the white (or yellow) balls as acue ball.Apointis scored when a shooter's cue ballcaroms on any two other balls in the sameshot(with the opponent's cue ball serving as anobject ball,along with the reds, for the shooter). Two points are scored when the shooter caroms on each of the three object balls in a single shot.A carom on only one ball results in no points, and ends the shooter'sinning.

Asian variations

A variant of four-ball is theEast Asiangameyotsudama(Tứ つ ngọc,Japanesefor 'four balls'),orsagu( tứ cầu,사구,Koreanfor 'four balls').

The game is played with two red object balls, one white cue ball and one yellow cue ball (or sometimes both cue balls are white, one having a red spot). Each of the two players is assigned a white or yellow cue ball; whether the opponent can use it as an object ball is a difference between the Japanese and Korean versions. A point is scored when the shooter caroms on two balls. A carom on only one ball results in no points, and ends the shooter's inning.

There are a few differences between theKoreanand theJapanesevariants:

• Starting position:In the Korean version, the cue ball is placed beside one of the red object balls for the opening shot, and play commences by hitting the red ball on the opposite side of the table (as inthree-cushion billiards). In the Japanese version, the cue ball is placed behind the second red object ball, and play commences by hitting the red object ball nearest to the cue ball.
• Object balls:In the Korean version, a player is penalized a point if the cue ball caroms off the opponent's cue ball. In the Japanese version, doing so is legal, as the opponent's cue ball is available as an object ball; caroming on all three balls scores two points.
• Winning:In the Korean version, after having scored the final point, a win is secured by doing a three-cushionshot; until one is successfully played, the player lagging behind can still catch up and win. In this respect, it is similar to the game play of thedartsgamecricket.In the Japanese version, the game is simply over when a player reaches the agreed-upon score.

Central European variation

A variation of four-ball calleddesítkový karambol(Czechfor 'tenfold carom') is popular inCentral Europe,especially in theCzech Republic.It is played with white ball, a blue ball, a yellow ball and a red ball which serves as the cue ball for both players. Players score a point by hitting two of the other three balls with the cue ball. A carom off all three object balls in one shot, however, scores 10 points. The score is doubled by hitting a cushion before hitting any of the other balls for a total of either two or 20 points in one shot.
