Leonardo Da Vinci. A man whose insatiable curiosity shows within every one of his many works. However, it was in the year 2011 that the most impressive of his plans were discovered and released by some talented people in the form of Fun da Vinci: yes, it seems that Leonardo was the inventor of the physics puzzle, and the world of casual gaming is all the better for it.

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.

If you ever felt that making breakfast should employ at least a ball, some strong and a winding mechanism, The Incredible Machine is the most brilliant game ever made. It uses the idea of a Rube-Goldberg machine, an overly elaborate setup to achieve a simple task. The Incredible Machine has spawned its own share of sequels, nearly all of which are present in this mega-pack. The idea is simple: each puzzle presents you with a different challenge to construct an elaborate chain-reaction towards a goal.

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.
