What are the payback requirements for slot machines in the Detroit casinos?

 

All slot machines must be designed to payback no less than 80% and no more than 100% of wagers over the lifetime of the machine.  It is important to understand that these payback percentage requirements are enforced for the overall design of the slot machine over its lifetime.  Each individual patron will not necessarily experience these payback percentages; they could be much lower or much higher.
