Quixo bears a superficial resemblance to Tic-Tac-Toe – with one player being crosses and the other circles, and with both trying to create a line of their symbol – but that's where the resemblance ends. The pieces in the game are cubes that have a circle on one side, a cross on another, and blank faces on the other four; to set up the game, players place the 25 cubes with blanks face-up on the 5x5 grid in the game board.
