Mills, et al slot machine makers and their genius
I have a 1931 War Eagle and that model as well as others and other slot makers always had such small payout cups. The question is WHY. It took many years for the machines to come out with a large area for payouts. My War Eagle is a 25 cent machine and hitting a jackpot you have to really have nimble fingers to get the coins out. I don't have big hands and I can only imagine with my difficulty getting the coins out it must be hell for guys with big hands.
