Factory Balls Forever

About Factory Balls Forever

Factory Balls Forever is a puzzle game about programming a small production line to paint plain white balls into a specific target pattern. Your tools are dipping tanks (which paint the entire ball), masking stencils (which cover part of the ball before a dip to preserve existing colour beneath), and removal tools that strip back individual layers. The target design is shown on the right; your job is to figure out the exact sequence of tool operations that produces it.

The elegance of the design lies in the constraints. Stencils only work if placed before a paint dip; dipping twice in the same colour has no effect unless you've painted over it in between. Complex target patterns require working backwards — asking 'what was the last step before the finished ball?' and reconstructing the sequence from the result back to the blank.

How to Approach Tough Puzzles

Identify the topmost colour layer in the target design first — that's always the last dip. Then identify what must have been masked to preserve the lower layers during that dip, which tells you the second-to-last operation. Continue backwards until you reach the blank. This deductive approach is more reliable than trial and error on complex multi-layer designs. Don't be afraid to reset and rebuild from scratch once you've identified the full sequence mentally.
