Plankly: Unscrew Puzzle

A machine of wooden planks is bolted together on your workbench. Unscrew the bolts one at a time. When a plank loses its last bolt it falls away and uncovers bolts that were hidden beneath it. Your bolt tray is small. Which bolt you take, and when, is the whole game. There is no timer. You never lose to the clock — you lose by filling your tray with colours you cannot finish, and you can always see it coming. It is a logic puzzle rather than a test of reflexes — a quiet brain teaser you can play offline, in short sittings, when you want to relax. The whole machine comes apart in the order you choose: every screw and nut, every plank, down to the bare workbench. FAIR BY CONSTRUCTION Most puzzles of this kind ask you to trust that the level is solvable. This one does not ask. • Every one of the 120 levels is run through an exact search before it ships. If it cannot be proven solvable, it is not in the game. • Three stars is not a designer's guess. The game computes the smallest number of tray slots any valid solution needs, and three stars means you matched it. • Hints come from that same search, so a hint is the correct next move, not a guess. • Boosters make a solution easier to find. They are never the only way to one, and a tray slot is never behind a prize wheel. WHAT YOU GET • 120 hand-verified levels across six worlds • A fresh machine every day — the same one for everybody, and solved before it is served • Badges for tight lines, not for grinding • A ranking based on levels cleared at par with no boosters • One-handed portrait play, offline, no account needed MADE TO BE READABLE • Bolt colours differ by stamped shape as well as by hue, so the matching still works if you do not separate red from green • Full text scaling No timers. No lives. No energy bars. Just the order you take the bolts out in. BENCH PASS Bench Pass is optional. It is an auto-renewing subscription, billed once a month, which switches off every ad and lends you every plank skin for as long as it is active. Skins are lent, not given: when the pass ends, any skin you did not buy outright with Cogs goes back. Players who have not subscribed before start with a 3-day free trial. Unless it is cancelled before the trial ends, it becomes a paid month and then renews every month at the price shown in the app for your region, charged to the store account that bought it, until you cancel. Cancelling stops the next renewal, and the pass keeps working until the end of the period already paid for. You can cancel at any time in your store account's subscription settings.
