Books have been set forth on this item, and the conflict and arguments about where the "hot" slot machine games are positioned in a casino are still taking place – 60 yrs after slot games were first placed in gambling houses.
The standard rule is that the superior one armed bandits were placed just inside the entry of the casino; so that people passing by would see jackpot winners … be captivated to come into the casino … play. Our thought is that this is definitely no longer the case.
The great majority of the major casinos presently are magnificent complexes and now you can’t see inside from the sidewalk, so there is no longer a reason to position the ‘loose’ slot games near any doors.
Another standard rule is that loose slots are placed on the major aisles in the casinos, again so that more potential gamblers could see winning jackpots and be galvanized 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 one armed bandits 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 perspective about where to place the loose slot games.
