Books have been written on this issue, and the disquiet and feuds about where the "hot" slot games are placed in the casino are still rampant – more than 60 yrs after slot games were first added to the gaming floor in gambling houses.
The classic rule is that the superior slot machine games were positioned just inside the main entryway of the casino; so that individuals walking by would be able to see real jackpot winners … be captivated to come unto the gambling floor and play. Our position is that this is definitely no longer true.
The great majority of the large casinos nowadays are jumbo complexes … it’s no longer possible to see inside from the sidewalk, so there is no longer a reason to situate the ‘loose’ slot machines near to any of the doors.
An additional classic rule is that loose one armed bandits are positioned on the major aisles in the casinos, again so that more fun seekers could see winning jackpots and be motivated to play. Importantly 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 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.
