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.
