How Infinity Tic-Tac-Toe Works: Rules & Winning Tips

Forget everything you know about draws. Here is how to master the 3-piece mechanic and crush your opponents.

Classic Tic-Tac-Toe has a major flaw: if both players know what they are doing, the game always ends in a draw.

Infinity Tic-Tac-Toe (sometimes called "Eat Tac Toe" or "3-Piece Tic-Tac-Toe") fixes this by adding one simple but revolutionary rule: The 3-Piece Limit.

The Golden Rule

Each player can only have 3 marks on the board at once. When you place your 4th mark, your 1st (oldest) mark disappears.

How to Play: Step-by-Step

3 Pro Strategies to Win

1. The "Center Trap"

In standard Tic-Tac-Toe, the center is king. In Infinity mode, the center is dangerous. If you take the center early, remember that it will be the first piece to vanish.

2. Predict the Vanish

Don't just look at the empty squares. Look at the oldest pieces. Ask yourself: "If I move here, does my defense disappear?"

3. Force the Error

Force your opponent to defend a spot that won't matter, causing them to delete their own key defensive piece.

Why Play This Version?

Infinity Tic-Tac-Toe transforms a simple game into a deep memory and logic puzzle.
