Hello how may I help you? Can you tell me the rules of tic tac toe? Yes the goal in tic tac toe is to get three x's in a row while taking turns placing one x on a 3x3 board. How can you tell the difference between each player's X? one player may use o's one may use x's or any other symbol they prefer. What happens if no one gets three in a row? If no player gets 3 in a row the game is a draw. Do the players switch who is X and who is O each time they play? It is up to the players if they want to switch symbols. Ok great, thanks! Your welcome.
