Players take turn in placing their colored disk on the board.

A “capture” is when a move is made with, for example, the black disk and a straight line (horizontal, vertical, or diagonal) is created between the new disk and another black disk with white disks in between. The white disks are then captured, i.e. switched to black disks.

The goal of the game is to have most disk of the assigned color when the game ends.
