Q*bert 
Atari 5200
Arcade
 
Hop Q*bert up and down the steps of a "three-dimensional" pyramid, changing each step's color as he lands. Complete the entire pyramid, and Q*bert moves to a more challenging pyramid. But look out! Crafty creatures are here, too, and they're after Q*bert. Hop out of danger fast - or soar to safety on a flying disc. But watch where you move Q*bert. One hop off the pyramid and he'll be lost in space!
