The objective of "Happy Wheels" is to move a vehicle through a course as quickly as possible without running into traps. There is no storyline in the "Happy Wheels" game.
There are several characters from which to choose when beginning a game of "Happy Wheels," and each character uses a different vehicle. The choice of character affects the gameplay because each vehicle behaves differently. There are many "Happy Wheels" levels available to play. This is because in addition to the levels created by the developer, Softonic, the game allows users to create their own levels of the game to play and share with other players.
