Demos of the Happy Wheels game are available at the Happy Wheels and Silvergame websites. This demo allows players to choose a course and then maneuver through it in an ill-suited vehicle, such as a wheelchair. The game has a variety of tricky or difficult levels, including Obstacle Course and TrapTrac.
After choosing a course, players then pick a character such as Wheelchair Guy or Irresponsible Dad. The gameplay can vary according to a player's choice of course and character. Similarly, the goal can vary from level to level, including collecting coins or making it to the finish line. When a character cannot get through a course, violent things can happen to it. Players use the computer keys to maneuver through the different courses.
