Overview: The same board and goal as classic tic-tac-toe, with one twist: each player can only ever have 3 marks on the board at once, which keeps the game moving until someone actually wins.
- Objective
- Get 3 of your marks in a row, column, or diagonal.
- Players
- 2 players, sharing one phone.
- Setup
- Enter both player names (or leave them blank for Player 1 / Player 2) and start — no other setup needed.
How Infinite Tic-Tac-Toe Works
- Players take turns tapping an empty square to place their mark, same as classic tic-tac-toe.
- The moment you place a 4th mark, your oldest mark vanishes from the board — shown as a dashed, faded square right before it disappears.
- That means the board is always shifting, and a draw is essentially impossible — you just keep playing until someone lines up 3 in a row.
- Winning
- Whoever gets 3 of their current marks in a row, column, or diagonal wins the round. Tap Play Again for a rematch with the score kept.
Tips
- Watch for your opponent's dashed "about to vanish" mark — it tells you exactly which square is about to open up.
- Great for killing a few minutes with just one other person and one phone — no setup, no players list needed.
