Stack blocks and clear them with a corresponding character or power block. Earn bonus points for scoring combos or clearing multiple blocks. There are three different block combos: orange/brown+Knuckles, gold ring+Sonic and emeralds (any color)+Tails. The more points you score, the faster the blocks will fall. You can play this game in the Timed mode (with highscores) or Freeplay mode (unrestricted playing time).
