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.

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.
