Volumes have been set forth on this matter, and the controversy and feuds about where the "hot" slot machine games are installed in the casino are still raging – over 60 yrs after one armed bandits were first placed in the casinos.
The quintessential rule is that the more favourable slot machine games were positioned just inside the entry of the casino; so that individuals going by would be able to see jackpot winners … be infatuated enough to come unto the gaming floor … play. Our presumption is that this is definitely no longer the case.
Most of the big name casinos presently are colossal complexes … it is not possible to see inside from the sidewalk, so there’s no longer a reason to position the ‘loose’ slot games close-by any doorways.
Yet another classic rule is that loose slot games are positioned on the major aisles inside the casinos, again so that more fun seekers could see winning jackpots and be galvanized to play. Notably 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 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!
These days, casinos are constantly changing their philosophy about where to place the loose slot machines.
