Frequently Asked Questions
Tic Tac Toe (also known as Noughts and Crosses or X and O) is a classic two-player game where players take turns marking cells in a 3x3 grid. The first player to get three marks in a row, column, or diagonal wins the game.
The game offers two AI difficulty levels. Easy mode makes random moves, perfect for casual play. Hard mode uses the minimax algorithm — an unbeatable strategy that always finds the optimal move, making it impossible to win against.
The best opening move is the center cell. From there, try to create two potential winning lines (a 'fork'). Always block your opponent when they have two in a row. With perfect play from both sides, the game always ends in a draw.
