The game starts with Q*Bert at rank 1. This is indicated by the number on the cube that Q*Bert stands on at the main menu. To reach rank 2, get over 60,000 points. To reach rank 3, get over 100,000 points. You can only change the color of the numbered cubes during game play if your rank equals or exceeds it.

To see your rank, on the Main Menu, Q*Bert will be standing on a cube with a number on it. That number is your rank. If you're rank 1, you can't step on any "special" cubes. If you're rank 2, you can step on cubes with a 2 on them. If you're rank 3, you can step on cubes with a 3 on them. You begin with rank 1.
