How to play:
Numbers float in and out of the Mystery Machine. You can use the arrows on the machine to browse through the history of input and output. You can chat a number to test an input. (Some results are kept secret.)
Once you think you know what's happening, sit on the chair, you will be given an input and 4 options for the output: chat the one you think is correct.

If you solve the puzzle you will be given a new box from the same level and you will receive a clam reward (once per level per day.)
