Books have been written on this matter, and the debates and discourse about where the "hot" slots are positioned in a casino are still happening – more than 60 yrs after slot machine games were first added to the gaming floor in the casinos.

The traditional rule is that the more favourable slot machines were located just inside the main foyer of the casino; so that potential players passing by would be able to see jackpot winners … be impressed enough to come unto the gambling floor and play. Our interpretation is that this is definitely no longer the case.

Almost all of the mega casinos these days are huge complexes and now you can’t see inside from the sidewalk, so there’s no longer a reason to place the ‘loose’ slots in close proximity to any entrances or exits.

Another traditional rule is that loose slot machine games are put on the major aisles in the casinos, again so that more potential players could see winning jackpots and be influenced to play. Notably 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 the slot machines 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!

In recent times, casinos are constantly changing their perspective about where to place the loose slot machines.
