As well as the option for 2 or 4 players, there are the following: - Sounds On or Off - Easy mode - To make it easier to complete the game, in Easy mode, overlays with your previously place block is allowed. Game ends when all squares on the grid have been filled - Hard mode - No overlaps are allowed, so it can take a while for the correct piece to be randomly generated... Game ends when any player(s) have no moves left, and are awarded a bonus to their block score, so don't be too quick to block someone in... Contains visual cues when positioning blocks and sound warning for incorrect Will retains settings and high score if 'Storage' permission is switched On, but it is not requested
