Happy Wheels is a game app that takes its name from the Flash game with the same title. The object of the game is to make your way to the end of each level in the game. You'll control different characters as you try to avoid the pitfalls of the levels, and your character will be riding some sort of simple wheeled machine, like a unicycle or a bicycle.

Unfortunately, it is not easy at all to get to the end of these levels. Your character is going to die often, and it will usually be in some horrifyingly grotesque manner. The game is no stranger to gore, and it contains gratuitous blood. Some might say that the game is purposely too difficult just so the player will be forced to play over and over.

The controls for the game are fairly straightforward even though they are based on touchscreen gestures. However, the game is annoyingly difficult, but that adds to the addictive nature. You keep coming back because you want to surpass the level that previously beat you. The game isn't for everyone simply because of the exceptional amount of violence and gore, but some won't be able to put it down.
