- The game is played on a grid that's 3 squares by 3 squares.
- The first player to play will be ‘X’ , while the next player will be ‘O’. Players will alternate on putting their marks on the grid.
- Players cannot play on an already played square.
- The first player to get 3 marks in a row (either horizontally, vertically or diagonally) is the winner.
- When all 9 squares are full, if no player has 3 marks in a row, the game ends in a tie.
