SOS game multiplayer

The classic paper and pen game we played at school, now for your mobile and tablet. The SOS game is also known as OSO in Spanish. This is a game similar to tic tac toe for two players in which the word SOS must be formed taking turns. Player must write the letters “S” or “O” in each cell of the board.
Invite your friends to play a game and challenge them! Like when we played it in childhood!


SOS is a two player-game where you have to form the word SOS in turns with the option of putting S or O in the empty boxes.

Players can write the word SOS horizontally, vertically or diagonally.
If one player manages to form the word, that player repeats a turn. The player with the highest number of SOS combinations wins the game.
