A da Vinci workshop, rendered in brass and gravity. In a lantern-lit workshop of brass and walnut, a marble waits at the top of a machine you cannot steer. Drag it into the top funnel and let go. Real gravity takes over, and the marble rolls, tips, and tumbles through the fixed contraption until it lands, ideally, in a bin that matches it. Then look again. Every piece that marble crossed has changed for the marble behind it. You plan the sequence. Physics does the rest. You never steer a marble in flight. You read the machine, then choose the order you drop them in. - The see-saw bit tips one way, then the other. The marble crossing it reroutes the next one. - The rotor does not toggle. It counts forward to its next exit with every pass. - The remote lever throws a switch from across the board. - The waterwheel never stops turning, so timing matters as much as logic. - The felt slows a marble to a crawl. It changes how late a marble arrives, never where it lands. - The wax seal carries the first marble across, then breaks. Every marble behind it drops through. Every marble in a bin that matches it, every bin filled, and the level is solved. A misfire is not a wall. Press the red knob and the machine re-cocks itself, ready for a new order. Walking out on a run already in motion costs your streak, so the machine asks first. What's inside - 100 hand-designed levels, rated one to five in difficulty - One new idea at a time: no two pieces debut on the same board - More waiting deeper in: the gilded marble, the cam tongue, the trapdoor, the pendulum, the drumskin, and the press - A weekly boards leaderboard to climb - Earn cogs as you play and grow your purse - The Cascade, a bonus brass pin board: no randomness in the drop, just physics - Three brass instruments to earn and spend: the Hourglass, the Blueprint, and the Apprentice Built like a puzzle box. Every surface is warm brass, walnut, or aged parchment, and every word is set in EB Garamond, the serif of an old draftsman's manual. Yours to play, quietly. No ads. No sign-in. No ad-tracking or ad-targeting software. DropOS needs no connection to play; anything synced for the leaderboard is anonymous by default. For anyone who loved the marble-drop puzzlers of the late 1990s, and for anyone meeting one for the first time. ## Key features - Physics-based contraption puzzles - Strategic marble dropping - 100 hand-designed levels - Weekly leaderboard - Earn in-game cogs - Bonus brass pin board ## Recent user reviews (1 of 1) All indexed reviews: https://appshunter.io/ios/app/dropos-marble-machine/id6788594506/reviews.md ### 5/5 — Nostalgia *2026-09-23* Brings me back to my childhood playing a similar game! 10/10!!!!

Your music now plays along with ours; Silent Mode hushes us, so turn it off to hear both. The card before you play gets to the point, and the rules say it plainly now: fill every bin. Tap a dotted word or a tile and its note opens right there, with an X to close it. Stuck? Some boards will tell you which marble to start with. Now, drop the marble. ### 1.0.2 — 2026-09-30 From our bench to yours: you can see the drop now. The marble rides above your finger, and a ghost shows where it will land. We quieted the cards, put pictures in help, and What's what is tiles now: tap a name to read its line. Your medals stay with the boards you earned. Cleared boards open again for returning players. Now, drop the marble. ### 1.0.1 — 2026-09-28 From our bench to yours: you showed us where the machine stuck, so we oiled the gears. A smoother start, a helping hand on tricky early boards, and clearer screen reader labels. Now, drop the marble. ### 1.0 — 2026-09-22 No release notes. ## Apps similar to DropOS | App | Rating | Price | Category | | --- | --- | --- | --- | | [Find 5 Differences Train Brain](https://appshunter.io/ios/app/find-5-differences-train-brain/id6481528942) | 4.6 (1,450) | Free | Games | | [Abstract Dark: Color by Number](https://appshunter.io/ios/app/abstract-dark-color-by-number/id6758203872) | 4.7 (605) | Free | Games | | [Cuty-Widget Pet](https://appshunter.io/ios/app/cuty-widget-pet/id6499506354) | 4.8 (5,206) | Free | Games | | [Spooky Halloween Color](https://appshunter.io/ios/app/spooky-halloween-color/id6459738674) | 4.6 (117) | Free | Games | | [Cheech & Chong's: Kush Kingdom](https://appshunter.io/ios/app/cheech-and-chongs-kush-kingdom/id6470943777) | 4.8 (10,339) | Free | Games | | [Merge Cooking®](https://appshunter.io/ios/app/merge-cooking/id1643509748) | 4.7 (50,664) | Free | Games | --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
