Volumes have been set forth on this matter, and the controversy and discord about where the "hot" slot machine games are placed in the casino are still passionate – sixty yrs after one armed bandits were first added to the gaming floor in gambling houses.
The quintessential rule is that the most favorable slots were located just inside the main entryway of the casino; so that folks walking by would see jackpot winners and be captivated to come unto the gambling floor … play. Our resolution is that this is no longer true.
Many of the mega casinos today are enormous complexes and it is not possible to see inside from the sidewalk, so there is no longer a reason to put the ‘loose’ slot games close to any entrances.
Yet another standard rule is that loose slot machine games are put on the major aisles in the casinos, again so that more fun seekers could see winning jackpots and be influenced to play. Importantly however, we find that this also is no longer a universal rule.
What casinos found over the years is that people walking down the busy aisles were frequently on the way to somewhere else. If they played slot machine games at all, they would simply put in their loose change because they happened to be walking by. Win or lose, they would very often not stop to keep playing. And the very last thing a casino wants is for someone to win a jackpot by playing only a few coins and then not stay to put it all back in!
These days, casinos are constantly changing their perspective about where to place the loose slot machines.
