Everyone likes games, especially our students. Fun and educational games are hard to come by, but the internet has everything doesn't it? While discussing a recent "indie" game, I was told of a game called
"Fantastic Contraption." This game involves the the
sandbox concept, which means you can solve the puzzles in any manner that you wish. There's just a simple goal of getting the pink ball to the pink area. I've included a screenshot, since embedding the flash for the game has the sound on and can be quite annoying.

The levels require some ingenuity and engineering experimentation to solve. After solving a level, you can also look at how other people completed it, so you can get more ideas! See how many you can do!
