“Your mission is to get the jobs on the top right done using the power sources on the top left. To do that, you'll have to build machines by connecting the pieces in the bottom middle.
To build your machine, click on one of the parts in the bottom of the screen, and then drag it into one of the three spaces. Try to do it as fast as possible. Once your machine works, click 'NEXT' to go on to a new challenge.”
