That would be the Airport. It is always amazing to Me that People play the slot machines at the airport. Slot machines are controlled to return a percentage of money back to the player, that is a fact and is regulated by the state but there is not a set number that the slot machine owner must follow. The only guideline that the slot machine owner must follow is if they advertise a certain number of return and do not follow it. And at the airport, the slot machine owner has no reason to advertise a percentage of return since there is no competition. The return at the airport will always be just enough for You to see a little bit of winning so You will believe You can win.
