Start by choosing a puzzle of your choice. Slide the card under the clear grid, then place the red gear and yellow wheel as indicated. Each puzzle will show you an array of color and sizes of gears, and how many of each you'll need (you'll see them printed along the bottom of the card). Pull those out (you MUST use all of them!).
Now: solve that puzzle!
Think you’ve solved the puzzle? Give the yellow wheel a turn and see if your contraption spins! If the red gear spins along with all of the gears you MUST use, you have just engineered a solution to the puzzle!
If not, return to your design board and give your problem-solving skills another whirl!
