How to Play Mello Yello Q*bert
Quick start
- Learn each diagonal hop near the summit.
- Land on cubes until they show the target colour.
- Use an available side disc when Coily closes in.
- On later rounds, avoid undoing cubes already finished.
Controls
The diagonally oriented four-way joystick selects the neighbouring cube to hop onto. There is no ordinary attack button. Jumping off an edge without a disc loses a life; a disc returns Q*bert to the top.
