🎯 Tips & Strategy — Tic Tac Toe
- Always take the center square if it's available — it's the most powerful position.
- Block your opponent's winning moves immediately — never let them get two in a row unchallenged.
- Force a fork by creating two winning paths at once — your opponent can only block one.
- Corner squares beat edge squares in strategic value — prioritize them.
- Watch for diagonal traps where the opponent sets up two threats simultaneously.
