Win tactical tic-tac-toe positions by dropping a cross or sliding one complete row sideways. Play 24 levels in each of three difficulties. The 3D playfield supports touch and mouse, with keyboard controls and optional sound.
How to Play Switchyard Noughts
Play an X in an empty square or shift a row sideways. A shift wraps the last square around to the other side. Make three Xs before the O player can connect three. A move that completes both lines is a draw. Choose Easy, Medium or Hard, then pick a level. Clear a stage to move on, or use the restart button to replay it.
