Volumes have been written on this subject, and the contention and disharmony about where the "hot" slot machine games are positioned in a casino are still rampant – sixty yrs after slot machines were first installed in gambling houses.
The quintessential rule is that the best slot machine games were positioned just inside the main entry of the casino; so that potential players passing by would see actual jackpot winners … be attracted to come inside and play. Our verdict is that this is definitely no longer the case.
Most of the mega casinos these days are huge complexes and now you can’t see inside from the sidewalk, so there is no longer a reason to place the ‘loose’ slots near any doors.
Another standard rule is that loose slot machine games are positioned on the major aisles in the casinos, again so that more persons could see winning jackpots and be roused to play. Nonetheless, 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 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 machines.
