This is one of my favorite puzzle games ever. It's incredibly addictive, at the end of each puzzle you will convince yourself that you are going to play just one more, but you're lying to yourself. I can't even begin to describe how cool some of the Rube Goldberg style machines are that you have to solve, and once you're done with all of them (and there is A LOT of content here), you can make anything you can think of using all the parts in the multiple games included in the pack. $10 is a ridiculous value for the amount of fun you will have, and it is perfect for laptops and older computers.
