PuzzleRig: Machine Lab
Place a part. Press Play. Watch it work.
How it plays
- Drag ramps, levers, swings, springs and wheels onto the board, then press Play
- Real physics: gravity, balance, momentum and springs decide what happens
- 55 levels in five worlds: Gravity Lab, Lever Works, Swing & Smash, Spring Yard and Machine Shop
- Three stars a level: solve it, use few parts, and find the bonus
- A dotted trail shows where the last run went, and a hint lights up when you're stuck
- A short science note with every solved level
What it doesn't have
- No ads, no in-app purchases, no account
- No Internet permission: it plays offline and progress stays on the device
- No timers, no lives
