XO

XO is tic-tac-toe, redrawn for 2026 — the same hand-drawn pencil-and-paper charm of the original 2016 game, rebuilt from scratch with seven ways to play. SEVEN GAME MODES • Classic — the timeless 3×3. First to three in a row. • Misère — the twist: making three in a row LOSES. Think backwards. • Wild — place either an X or an O on your turn. Mind games guaranteed. • Blitz — five seconds per move. Hesitate and a random square is played for you. • Gomoku — five in a row on a big 9×9 board. Deep and addictive. • 4 Players — pass-and-play for four, each with their own mark, racing for four in a row. • Ultimate — nine boards inside one. Your move decides where your opponent must play next. PLAY YOUR WAY • Solo vs the computer on Easy, Medium, or Hard. Hard plays perfectly — the best you can do is force a draw. • Pass-and-play with up to four friends on one phone. • Hints and undo when you're learning. KEEP COMING BACK • Campaign — climb an eight-rung ladder of AI rivals, each tougher than the last. • Daily Challenge — a new mode every day and a win streak to protect. • Stats, streaks, and achievements to chase. MADE TO FEEL GOOD • The original hand-drawn grid and X/O artwork, now animated — marks spring in, the winning line scribbles itself across the board, and wins burst into confetti. • Three themes: Paper, Chalkboard, Blueprint. Light and dark. • Satisfying sounds and haptics. Free to play, with ads. No account required. Just open it and play.
