I used to love those "pusher" machines. My favorites were at Slots A Fun. I would wait until the last person fed in $20 in quarters before giving up then put in my one or two and take a few nice wins. The machines at the carnivals and on cruise ships are made a little differently and pay almost nothing compared to the Vegas machines. When I was on the Nieuw Amsterdam last year they reset the machine after every shore stop. No one ever won one of the big prizes the whole trip. I would love to buy one of those machines for my casino room.
