Crazy Machines Golden Gears is a new addition to the Crazy Machines series of physics building/puzzle games. The franchise has made the leap from downloadable desktop game to the mobile world, bringing with it all the challenge, creativity and, well, crazy machines you can imagine. If Rube Goldberg only knew the kind of legacy he would leave to the casual gaming world.

Ready for more buildings, contraptions, machines, and inventions? Crazy Machines: New from the Lab is another resurrected hit from German game developers FAKT Software. Featuring gameplay very similar to The Incredible Machine, Crazy Machines features over 100 new levels, each one more complex (and zany) as the last.

Resurrected from 2007 where it rested in relative obscurity, Crazy Machines: Inventor Training Camp is a follow-up to the original Crazy Machines game that features more Rube Goldberg-like physics puzzles. Use a variety of objects to assemble crafty "devices" that accomplish different tasks. The setup is something you might see in The Incredible Machine, though Crazy Machines streamlines the process with much simpler building mechanics, fewer pieces to fuss with, a better visual presentation, and more directed goals.

Released in 2005 by German game developers FAKT Software, Crazy Machines was a cult classic that only recently began to breach the barrier to "fan-favorite" status among casual gamers. Publicized mainly by word of mouth, this out-of-the-ordinary puzzle game staked its claim as the next-generation leap from The Incredible Machine, which reached its height of popularity almost a decade earlier. The common theme in both games is the use of Rube Goldberg-inspired machines and contraptions to solve a puzzle or obstacle in each level.
