Xonogrid

Xonogrid is tic tac toe with a twist.

Play the classic game, or switch to Limited Pieces: each player keeps at most three pieces on the board, and placing a fourth makes your oldest piece fade away. The board never fills up, draws become rare, and every move matters right to the end.

TWO WAYS TO PLAY • Traditional: classic rules, fill the board. • Limited Pieces: three pieces each, the oldest fades. A fade hint shows which piece leaves next.

PLAY ANYONE • Pass and play: two players, one device, panels facing each side. • Face the AI: Easy, Medium, or Impossible. Impossible plays perfectly and has never lost. Can you force a draw?

BEAT THE CLOCK • Add an optional clock: a limit for each move, or a total time bank for the whole game. • Run out of time and you lose. Presets included, or set your own.

EVERY GAME REMEMBERED • Finished matches are saved automatically. • Replay any game move by move, with the time each move took.

MADE WITH CARE • Designed for iPhone and iPad. • Crisp haptics and satisfying sound. • No account, no ads, no tracking. Plays entirely offline.
