Thank you for downloading Tic Tac Toe Classic. Also known as Noughts and Crosses or Three in a row, Tic Tac Toe is a paper and pencil game between two players marking the spaces in a 3 × 3 board alternately. A player wins if he can have a line of three symbols: the line can be horizontal, vertical or diagonal. This variant works with three chips maximum per player. Once each player has all their chips in play, they should change their position to keep playing and get three in a row. You can play with another person or against the form on Artificial Intelligence (Ai). Tic Tac Toe is a game for all ages.
