Synopsis:
Superboy is contacted by the owner of a plastics company to help retrieve a missing formula. The formula was hidden inside a small round ball, that the owner's son mistook for a marble. The marble was then lost.

Superboy stages a marbles tournament for all the local boys. He then defeats them all personally and wins the marbles. He takes his winnings back to the company, where the missing formula is found.

Then, as Clark Kent, Superboy redistributes the other marbles back to the other boys by losing to them. After the tournament, Superboy builds the boys a new playground with equipment donated by the plastics company.
