Summary: A few years ago I purchased Mechanic Masters 1 and 2, Logic Machines, and Gravity. Ever since, I've been looking for similar DS Games, but couldn't find any until I came across Crazy Machines. I love it!
Summary: This game can be difficult at the higher levels, but the rewards are worth it. When my son starts playing it he becomes captivated by the challenge. It can be frustrating at times because of the difficulty though.
