Bumper pool is a casual billiars game played on an octagonal (or, uncommonly, rectangular) table with one pocket centered on each end. Most tables have 12 bumpers, although some tables have 14 or 16. Two bumpers surround each pocket with the other eight arranged on the table's midlines leaving a center space just large enough for a ball to pass through. Tables with 14 bumpers have three rather than two bumpers on each side of the center space on the line midway between the two holes. The game is played with 5 red and 5 white balls, with one marked ball in each set. The game may be played in a much smaller room than most billiards games because the tables are much smaller. This type of billiards is mostly played in France.[dubious – discuss]
