This game is inspired by a mobile app of the same name, where the touchscreen is used to fill in a puzzle so that all the pieces are the same colour. The C64 conversion has multiple level packs (with eight puzzles in each pack) which are loaded in and gradually get harder.
Each puzzle has three colours and a maximum number of steps (fills) to complete it in. The filling of the colours is a nicelydrawn graphical effect, and the presentation is basic but clear.
While it is initially engaging there is little incentive to return once the puzzles have been solved.
