There are two objects to this game:
A. Correctly guess which three of the six planets the computer has chosen.
B. Correctly guess in which black box each of the three planets are located.
Here is an example:


6. Now go up to the second row and follow steps 1 5 again. In this example, we chose "Venus" again, but we put it in the left large square instead of middle large square like we did in the first row. We click submit and one of the small squares turns "black". This tells us that "Venus" is one of the mystery planets and that Venus is in the exact right square. Now you have to figure out the other two planets and their location.

7. Now we go up to the third level and follow steps 1 5 again. In this example we put Venus in its correct spot and we put Mars (red) and Io (green) in the second and third large squares and then we clicked the third submit.
8. Here is the feedback from the third try. The one black square means we have correctly guessed one of the three we know that Venus is correct from our second try. The two green squares tell us that Mars and Io are the other two mystery objects, but that they are in the wrong places.

9. We Won!! We followed steps 1 5 again and correctly put all the right mystery objects in their proper places This is shown by the three black squares. Thumbnails of the planets/moons show up at the top!
