Volumes have been said on this item, and the disquiet and feuds about where the "hot" slot machine games are placed in a casino are still ongoing – more than 60 years after the slots were first placed in casinos.
The classic rule is that the superior slot games were installed just inside the main entryway of the casino; so that fun seekers going by would see jackpot winners and be enthralled to come unto the gambling floor … play. Our inference is that this is definitely no longer so.
Just about all of the mega casinos presently are oversized complexes and it is not possible to see inside from the sidewalk, so there is no longer a reason to situate the ‘loose’ slot games near to any doorways.
An additional standard rule is that loose slot games are installed on the major aisles inside the casinos, again so that more persons could see winning jackpots and be roused to play. Notably though, 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 slot games 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 philosophy about where to place the loose slot machine games.
