Move Wudywurm around, let him eat the colored blocks and match 3 or more of the same color. Keep dragging him to make him longer before you release it. Make combos and fill up the gate meter. The first levels are with a single Wudywurm, later on you have to control multiple in the same play field. Like the famous snake game, this is an addictive skill game. Play the 15 chamber mode or the endless mode. Beat the highscores of other players. See the how to play screen for more info.
