How it works

Spell SOS in every direction.

Take turns placing an S or O in any empty cell. Each new horizontal, vertical, or diagonal SOS is worth one point, and a scoring move earns one bonus turn. If one move makes several sequences, score each one. The game ends when the board is full or both players agree to stop; the higher score wins.
