XO: Tic Tac Toe with a Twist

The tic tac toe you grew up with - reinvented. XO takes noughts and crosses (the classic Xs and Os) and spins it into several distinct game modes, from the timeless 3x3 grid to brain-bending variants you've never played. A quick two-minute match or a long strategy session - it's all here, and all offline.

Every mode is hand-drawn on a chalkboard, with a calm, clean look and a genuinely sharp AI opponent across Easy, Medium and Hard. No noise or clutter - just the game.

WHY YOU'LL KEEP IT INSTALLED
- No ads. None. Not between games, not anywhere.
- No paywall and no in-app purchases - the entire game is free.
- Fully offline - no wifi, no mobile data, no account, no sign-up.
- Single player vs a smart AI, with 3 difficulty levels.
- Per-mode winning streaks to build and chase.

7 GAME MODES
- Classic: The original 3x3 board. Three in a row wins. Simple and timeless.
- Gomoku: Five in a row on a big board - also known as Five in a Row or Gobang.
- Infinite: You only ever hold three marks. Place a fourth and your oldest one vanishes, so the board never clogs and the game never stalls in a draw.
- Gravity: Drop your marks and let them fall, Connect-style. Line up four - but careful, pieces can be pushed out from under you.
- Toe-Tac-Tic: Everything in reverse - make three in a row and you LOSE. Easy to learn, devious to master.
- Notakto: Both players share the same mark. Complete three in a row and you're out. Pure tactical tic tac toe.
- Order & Chaos: On a 6x6 board, Order races to make five in a row with either mark, while Chaos fights to stop it.

Whether you call it tic tac toe, tic-tac-toe, noughts and crosses, or X and O - if you love quick, clever board games and brain teasers, XO is built to earn its place on your home screen.

Pick a mode. Beat the AI. Build your streak.
