Carrom is played on an extremely smooth and flat wooden board. Two concentric circles are drawn at the center of the carrom board. At each corner of the square board there is a small circular pocket that projects inwardly on the board, rather than outwardly like a pool table. Two lines run parallel to each edge of the board, with the line that is closer to the edge being slightly thicker than the other. One foul line arrow, originating near the larger center circle, points to each pocket on the board.
