Books have been set forth on this item, and the disquiet and ruckus about where the "hot" slots are placed in the casino are still rampant – more than 60 yrs after slots were 1st installed in gambling dens.
The quintessential rule is that the more favourable slot machine games were positioned just inside the entrance of the casino; so that people passing by would be able to see jackpot winners and be impressed enough to come into the casino … play. Our conviction is that this is definitely no longer so.
Practically all of the large casinos nowadays are monstrous complexes and it’s no longer possible to see inside from the sidewalk, so there’s no longer a reason to place the ‘loose’ slot machines in close proximity to any doorways.
Yet another classic rule is that loose slot machine games are positioned 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 isn’t 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 slot machines 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!
In recent times, casinos are constantly changing their perspective about where to place the loose slot machine games.
