A walkthrough of the ZX Spectrum game, Ball Crazy. A 1987 game published by Mastertronic. Use Erik the ball to change the colour of the blocks to the colour indicated at the top. When all the blocks are the same colour a new layer is placed on top of the last. This will happen until there are four layers, when the screen will be cleared and a new level begins. There are six levels in total with progressively more enemies, after which the game loops around back to the first, which is where this walkthrough ends.
From the recording originally sent by Paul E. Collins to http://www.rzxarchive.co.uk/ . Recorded using "rollback", a feature of the emulator which allows you to mark a point, which you can then roll back to later if you get into difficulty, and try again.
