You can play any of the standard 3x3 or 4x4 puzzles in any order, or you can try any of the 3x3 or 4x4 custom levels -- if you enjoy the smaller puzzles and want to play 5x5 or 6x6 levels, you can purchase a level pack through MochiCoins! (You can also purchase the level editing tool, so you can submit your own custom levels.) Once the level begins, click on a tile adjacent to the empty slot to swap the tile and empty space. (Just like a sliding block puzzle.) To complete the level, match the tiles to the pattern requested by the little character in the corner of the screen. The empty slot MUST BE in the lower right corner of the puzzle to complete a level. Benevolence will keep track of your shortest times and fewest moves for all the standard levels, so you can try to beat your best time or try to solve the levels in fewer moves than before.
