How to play Cube Composer?
A puzzle about functional programming in disguise. You start with a stack of colored cubes and a target pattern to match. From a palette of transformation functions — recolor, stack, duplicate, drop — you drag tiles into a pipeline that runs left to right over the stack. The output updates live as you build, so you can see exactly how each function reshapes the cubes. Match the target to clear the level.
- Add a transformation — Drag a function tile into the pipeline
- Remove / reorder — Drag a placed tile out or to a new slot
- Fullscreen — Press F or click the expand icon
Read the target from the output backward. Work out which final transformation produces it, then build the steps that feed into it.
Order is everything — the same two functions in the opposite sequence give a completely different stack. Swap them and watch the preview.
Keep your pipeline short. The cleanest solution is usually the smallest set of functions, not the cleverest one.
