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.

System Mania is an arcade game that borrows liberally from the ever-popular resource management genre. Instead of serving food to customers, however, you spend your time fixing their strange contraptions by turning off warning lights as they appear. The fate of Fiona's growing fix-it shop is in your fast-clicking fingertips, so pull levers, spin wheels, and flip switches as quickly as possible.

Goldburger To Go is a short flash game where you must position various components in a Rube Goldberg-type device in order to assemble a tasty (but unhealthy) snack on a skateboard at the end.

At first glance the game appears to be a layout from a schematic diagram, which might easily scare you away if you're a non-technical type. And it will likely have you scratching your head wondering just what to do with it even if you are an electrical engineer. However, those adventurous souls that persevere, by poking around the surface to learn what is hiding underneath, will be nicely rewarded by what they find.

A cross between a point-and-click puzzle game, interactive art, and a Rube Goldberg invention, Treasure Box is a gorgeous and fun little Flash game that puts you to the task of finding the treasure of a king long since passed. It's a short and beautiful interactive multimedia adventure from an artist with a purpose.
