SFIRS, phonetic writing for the word 'spheres'. Why? Because there aren't any spheres in the game, just cubes, so the name helps compensate... SFIRS applies truly unique mechanisms for placing and capturing pieces (cubes). Be the last player to be able to make a move and win the game. But when do you sacrifice your cubes for better area control? And when is it wise to chain moves in order to get ahead?
