Books have been said on this item, and the bickering and discourse about where the "hot" slot machines are located in a casino are still rampant – sixty yrs after the slot machines were first placed in gambling dens.
The quintessential rule is that the better slot games were positioned just inside the main foyer of the casino; so that individuals walking by would see jackpot winners … be keen enough to come inside … play. Our thought is that this is definitely no longer so.
The great majority of the mega casinos today are colossal complexes … now you can’t see inside from the sidewalk, so there’s no longer a reason to place the ‘loose’ slot machine games near to any exits.
An additional traditional rule is that loose slot machine games are located on the major aisles inside the casinos, again so that more persons could see winning jackpots and be roused to play. 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 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.
