Books have been stated on this subject, and the disquiet and discord about where the "hot" slot games are positioned in a casino are still taking place – more than 60 years after one armed bandits were 1st placed in gambling dens.
The standard rule is that the more favourable slots were positioned just inside the main doorway of the casino; so that fun seekers passing by would see real jackpot winners … be impressed enough to come inside and play. Our thought is that this is definitely no longer the case.
The great majority of the mega casinos presently are huge complexes and it’s no longer possible to see inside from the sidewalk, so there’s no longer a reason to situate the ‘loose’ slot machine games close to any doors.
Another standard rule is that loose slot games are placed on the major aisles in the casinos, again so that more folks could see winning jackpots and be galvanized 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 machine 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!
Nowadays, casinos are constantly changing their philosophy about where to place the loose slot machine games.
