Any help on Level 45?
I looked up all the subclass of Patent Class 29 (U.S & International) as they might pertain to the service court, service box, tennis, ball, whatever, and every single number I tried didn't work.
Is the answer a number, or do I need to put "subclass" in front of it, too?
Or does this have nothing to do with any tennis terms at all and that pic was just to mislead?
