💡Conseils
- ★Always take the center square (position 5) if it is available.
- ★Corners are more powerful than edges — control the corners.
- ★Watch for "fork" opportunities: a setup where you threaten to win in two ways at once.
- ★Against the Hard AI, your only realistic goal is a draw — focus on blocking forks.
ℹ️À propos
Tic Tac Toe is one of the oldest strategy games in recorded history, with origins traced back to ancient Egypt around 1300 BC where versions of the game have been found carved into stone. Despite its deceptively simple rules, the game has a perfect mathematical solution. When both players play optimally, every game ends in a draw — meaning the best you can ever hope to achieve against our Hard AI is a tie.
