Books have been stated on this item, and the controversy and discourse about where the "hot" video slots are located in a casino are still happening – over sixty years after slot machine games were first placed in the casinos.
The classic rule is that the very best slot machines were positioned just inside the main door of the casino; so that people going by would see jackpot winners … be inspired to come unto the gambling floor … play. Our assurance is that this is no longer the case.
Practically all of the big name casinos these days are monstrous complexes … you no longer can see inside from the sidewalk, so there is no longer a reason to put the ‘loose’ slots in close proximity to any entrances or exits.
An additional traditional rule is that loose slot games are installed on the major aisles in the casinos, again so that more people could see winning jackpots and be roused to play. Interestingly though, 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 the 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 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 machine games.
