Q*bert

Q*bert (also known as Qbert) is an arcade game developed and published for the North American market by Gottlieb in 1982. It is a 2D action game with puzzle elements that uses isometric graphics to create a pseudo-3D effect. The objective of each level in the game is to change every cube in a pyramid to a target color by making Q*bert, the on-screen character, hop on top of the cube while avoiding obstacles and enemies. Players use a joystick to control the character. (Wikipedia)
