Happy Wheels is a simple physics based game where you need to control your character sitting on a vehicle and move him forward to reach the finish line. It looks easy but you find that you have to make great efforts in keeping the vehicle moving without hitting the hurdles that can send the character flying up in the air. Accident in this game means lots of graphical violence as there is blood spilling on the monitor. Despite its simplicity and ordinary graphics, Happy Wheels has become very popular.
