Volumes have been said on this topic, and the disquiet and discourse about where the "hot" slot games are placed in a casino are still rampant – over 60 years after slots were first installed in the casinos.
The standard rule is that the superior slots were located just inside the entry of the casino; so that people going by would be able to see real jackpot winners … be enthralled to come into the casino and play. Our slant is that this is definitely no longer so.
The great majority of the big name casinos these days are mammoth complexes and it is not possible to see inside from the sidewalk, so there’s no longer a reason to have the ‘loose’ slots near to any doors.
An additional traditional rule is that loose slot machine games are positioned on the major aisles inside the casinos, again so that more potential gamblers could see winning jackpots and be encouraged to play. Nonetheless, we find that this also is not a universal rule any more.
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 slots 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 philosophy about where to place the loose slot machine games.
