Screw Machine is a color-sorting screw puzzle with a moving twist. Instead of stacking screws onto a bolt, you spill screws onto a spinning machine and let timing do the sorting. Tap a panel drop its screws onto the rail, and watch each color thread itself into its matching plate as the ring carries it around. Fill every plate to win. Overload the rail and the whole machine seizes up. HOW THE MACHINE WORKS • Tap a panel to loosen its screws onto the spinning rail • Four color plates sit around the ring — each one takes three screws of its color • As the machine turns, every screw passing its matching plate drives itself in • Fill a plate and it locks shut; the next color rolls up behind it • Clear all the plates to finish the level KEEP IT TURNING • The rail only holds so many screws, release colors with nowhere to go and it jams solid • Read the machine before you tap: open the panels whose colors have an open plate • No move counter, no timer, you only lose if the rail jams for good • Every level is a small sorting puzzle built to be untangled PARTS THAT CHANGE THE GAME • Mystery plates: The next color stays hidden behind a "?" until it rolls into place • Gates: Run a screw through and it splits into more • Tunnels: Feed a whole extra run of panels onto the board • Arrows: Panels that you can only unlock from a certain direction WHY IT'S HARD TO PUT DOWN • A fresh, tactile spin on the nuts and bolts puzzles you already love • One-tap, simple, with real timing and planning underneath • Hand-built levels that stay clever without ever feeling like work • Oddly satisfying to watch, screws driving home, plates locking in sequence • Play offline, anywhere, no wifi needed • Free to play, with lives that refill over time Loosen the screws. Run the machine. Sort every color. ## Key features - Spinning machine sorting mechanic - Color-matching screw puzzles - Tap-to-release screw panels - Special game-changing parts (mystery plates, gates) - Offline play - No timer or move counter ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | 10000 Coins | $14.99 | one-time | | 1000 Coins | $1.99 | one-time | | 5000 Coins | $7.99 | one-time | | Small Bundle | $9.99 | one-time | | Medium Bundle | $19.99 | one-time | | Large Bundle | $29.99 | one-time | | Mega Bundle | $49.99 | one-time | | Fail Offer | $4.99 | one-time | | No Ads | $7.99 | one-time | | No Ads Bundle | $12.99 | one-time | ## Recent user reviews (3 of 3) All indexed reviews: https://appshunter.io/ios/app/screw-machine/id6801033982/reviews.md ### 5/5 — Nice format *2026-10-11* There are a billion games of this type, but I really like the appearance and gameplay of this one. It met my standards of games I’m happy to pay to have ads removed. Developers deserve something and my time is worth enough to cough up a bit for games that I want to play for more than the 10-20 levels that casual games typically let you play before the commercials start. I do hope that they add a bit more–like challenges–in the future. I’m a sucker for that kind of dopamine hit. But I will play it occasionally even without additions. ### 5/5 — Nice game *2026-10-03* Satisfying ### 1/5 — SCAM!!! *2026-09-26* It poses as a free game but charged my card $100!!!! ## Frequently asked questions about Screw Machine ### What is Pocket Screw Machine?
