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
