Winning Strategies: How to Beat the AI

Want to improve your win rate? Keep these strategies in mind:

The Center is Key: In a 3×3 grid, securing the center square gives you the most possible winning lines (4 lines intersect the center).
The Corner Trap: If you take a corner and your opponent takes the middle, try to take the opposite corner to set up a “fork”—a situation where you have two winning moves, and your opponent can only block one.
Defense First: Always scan the board to see if your opponent is about to connect their line. blocking them is more important than building your own line.
