PYD Slot Machine LeasingThere are a number of reasons why a casino would choose to Lease their machines instead of buying them. I would think some more important factors are that slot machine technology is upgraded frequently, and gambling preferences change on a regular basis. For a casino to constantly buy new machines to keep up with demand would be completely unrealistic. It is far more practical to rent the machines. If slots were such a terrible business and unprofitable, chances are casinos wouldn't waste space putting them on the floor.
