Totaljerkface, the development team behind the game “Happy Wheels,” hasn't made a Happy Wheels 6 game as of June 2015. The original game is available on arcade websites such as Pum6.com.
“Happy Wheels” is a physics-based game in which players control a character on a variety of wheeled objects such as wheelchairs, bikes and scooters. The goal is to reach the end of the stage alive. Players use the arrow keys to move and press the Z key to eject the character from the vehicle. Additionally, they can press the space bar to perform the character's primary action and the Shift and Ctrl keys to perform the secondary action.
