Are slot machines programmed?
Yes, they are programmed. However, the programming is done by the casino, not by the manufacturer. The casino programmers are looking at variables like paytable settings and coin denominations, and they are also taking into account player behavior (any history of wins or losses). They are also looking at player expectations and other factors.
