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. FEATURES - 500+ levels across 7 difficulty tiers, Easy to Grandmaster - A solver-computed par and star rating on every puzzle - Daily & Weekly challenges with streaks and iCloud sync - Hardcore Mode — a countdown clock and only 3 undos - Deep Sort — an endless 12–13 color campaign for experts - Mini Games — Shell Game, Void Memory, and a 50-level Rush Campaign - Customize tubes, fills, and backgrounds with tokens you earn by playing - 37 Game Center achievements - Colorblind mode and Reduce Motion support No subscriptions and no third-party ads. A one-time purchase unlocks every mode — optional token packs are there if you want a boost, but you can earn everything just by playing.
