This game is somewhat similar to tetris: blocks fall to the bottom of a rectangular area. However, the rules of Sonic Heroes Puzzle are different from tetris: Blocks are composed of Sonic characters and objects associated with them. Rings are associated with Sonic, Bricks are associated with Knuckles and emeralds are associated with Tails. Once a character lyes next to its associated object, both are eliminated. If there are several equal objects lying one next to another they all are eliminated once you lay an appropriate character next to them.
