Blackbox was a game invented in the early 1970s by Eric Solomon. (He got his inspiration for the game from Godfrey Hounsfield, the British researcher who invented the CAT scanner.)  The game consists of sending "beams" into a square box via any of the 8 "ports" on each side.  One of three things can happen to the "beams".  They can:
- strike an "atom" directly and be absorbed
- glance off one or more atoms and be reflected back
- come out another port, possibly being reflected along the way
The objective is to deduce the locations of the atoms by the behavior of the beams.

You can try playing the game here. Note that on this website, the atoms are referred to as "balls".

If the above website is down or you want a further explanation, here is the wikipedia web page for the game.

To solve the puzzle, you'll have to find the atoms contained in two blackboxes based on the clues shown below.
