Happy Wheels is a ragdoll-physics-adventure based flash game created by Jim Bonacci. Players control various unique characters with their goal being to get to the finish line and avoid being splattered across the level by many hazards and obstacles. Users may create and share their own custom scenarios using the expansive level editor, or play some of the 1.7 million already-existing user-made levels. The game is most notable for its dark sense of humor and its large amounts of gore.
