The Incredible Machine is fun but gets harder once you get farther into the game. It takes a Ton of brainpower to get past the puzzles after the tutorial puzzles. One of them is to get a little munchkin to his home. See if you can figure that out. I did, in three days! The puzzles are fun but hard because you have different tools to choose from. The tricky part comes in some puzzles when you don't need all the tools. I recommend this game to people who like fun games.
