Winning Strategies
Center Control
Always take the center square if available on your first or second move. It gives you the most winning opportunities.
Corner Strategy
If the center is taken, choose a corner. Corners create more three-in-a-row possibilities than edges.
Block Your Opponent
Always block your opponent if they have two in a row. Defense is just as important as offense!
Create Forks
Try to create two winning threats at once (a 'fork'). Your opponent can only block one!
Pro Tips
The center square is the most valuable position
Corners are better than edges for winning opportunities
