Watch it run
What's inside
100+ levels all over the house
- Garage: ramps, balls, dominoes, springs and seesaws
- Bedroom: balloons, needles, scissors and marbles
- Living room: ropes, pulleys, gears, belts and wind-up motors
- Kitchen: conveyors, pistons, switches, wires, fans and a wind-up mouse chasing the cheese
- Basement: crates, anvils, winches, generators and tubes
- Fireplace: candles, fuses, rockets, firework barrels and a circus cannon, with toy-like fire
- New rooms arrive in updates
Stars that mean something
- ★1 solves the level and opens the next one
- ★2 asks for a leaner machine with fewer parts
- ★3 is an extra challenge that really changes the solution
- More than one way to solve it: if your machine works, it counts
Physics you can trust
- The same machine gives the same result, every time, on every device
- Parts snap to a grid: nothing depends on hitting a single pixel
- Undo and redo, simulation speed, and Stop puts everything back
Nobody gets stuck
- Hints in three steps: a clue, where one part goes and, if you need it, the solution
- Stuck? Unlock the next level and come back later
- Every level can be solved without a hint
Your way
- Three visual themes: Pop, Blueprint and Tin
- Touch controls made for phones
- Plays offline
- English and Portuguese
Free to play
- All levels are free
- Video ads only when you choose to watch one, for a hint or to unlock a level
- No ad ever opens on its own, between levels or while your machine runs
- Optional one-time Inventor purchase: hints and unlocks without videos
