Grainfall is a color-sorting puzzle that knows the perfect score. Every level runs through a real solver, so the game knows the exact fewest moves — the par — before your first pour. Match par for 3 stars and see exactly how close to perfect you played.
Pour liquid between tubes until every color lands in its own tube. Simple to learn, hard to perfect.
