Crazy Machines: The Wacky Contraptions Game (PC & Mac) review:
5 stars (Super Fun!) - This is an awesome, good, clean game that will provide hours and hours of entertainment. Remember Rube Goldberg? You can build Rube Goldberg-esque machines and put them into motion. You can also "solve" puzzles by figuring out what things to put where to make your crazy machine do something - like lighting a candle or launching a rocket.

Our kids also like to work together and also with their friends - not always something we see when they play on the computer - so it's great for families and friends to play all together. I like the way the people who made this smuggled the physics in there with the fun. How nice to see intelligence combined with real fun.

(We got this for our kids but we are having fun with it too.)
