Back in the 80's when my local house had moonlight bowling (and part of the 90's), you would get a dollar for a red head pin strike, and if the colored pins appeared in the 1-7-10 spots and you struck it was $10. Splits varied from $ .50 for a baby split to $50 for the 7-10. You also got money for games over 200, and I think a 300 game was $100.
Sometimes for the $10 fee to bowl I would come away making double that...but most of the time it was a donation as the lanes were very dry.
