The "Happy Wheels" iOS mobile app is free to download via the app store and available for PC users to play online at the official Totaljerkface.com website. "Happy Wheels" was released for mobile users on August 19, 2015 and is also available in an ad-free version for $1.99, as of 2015.
"Happy Wheels" was created by Jim Bonacci in 2010. It features ragdoll-physics gameplay which contains graphic violence, including animated blood spatter and decapitations. To play the game, users must navigate one of several characters through the level while utilizing a wheeled vehicle. Examples of vehicles in the game are a Segway, a wheelchair, a bicycle and a moped.
One of the game's main draws is that it offers a level editor that allows players to create custom maps. Avid players have produced a large amount of custom content which is available on a public server for others to play.
