Volumes have been said on this issue, and the debates and face-offs about where the "hot" video slots are located in the casino are still passionate – more than 60 yrs after slot machines were first placed in gambling houses.
The standard rule is that the superior slot games were located just inside the main door of the casino; so that persons walking by would be able to see actual jackpot winners and be smitten to come unto the gambling floor and play. Our slant is that this is definitely no longer the case.
Most of the major casinos these days are gigantic complexes and it’s no longer possible to see inside from the sidewalk, so there is no longer a reason to place the ‘loose’ slots near to any entrances.
Yet another traditional rule is that loose slot 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 though, 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 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!
Nowadays, casinos are constantly changing their philosophy about where to place the loose slot games.
