Fantastic Contraption Prius
Make the best ecologically sound contraptions you can in this game. Use your different options to move the wheel into the blue box. You can choose from many different fuel sources, like water or solar power! You need to connect the fuel sources to the different wheels, then press the start button to see if your contraption is working correctly. If not, press stop and use the delete key to start over. You will have to make your way through increasingly difficult levels as you progress through the game. This is a one player game.
