The game of Othello is played on a board with 64 squares, arranged as 8 columns and 8 rows. The game pieces have the shape of discs which have a black side and a white side. Black always put the pieces down with the black side up, and White with the white side up. Black must always go first. Pieces can only be played on empty squares, and stay on the same square until the end of the game. To make a legal move, the played piece must bracket one or more of the opponents pieces in any direction between two pieces of the played color. All the pieces bracketed in every direction are then flipped to show the played pieces color. If a player cannot make a valid move he or she must pass. If both players cannot make moves the game ends. The player with the biggest number of pieces wins.
