Volumes have been set forth on this subject, and the disquiet and feuds about where the "hot" one armed bandits are placed in a casino are still taking place – more than sixty years after slots were 1st placed in gambling dens.
The classic rule is that the better slot machines were installed just inside the door of the casino; so that fun seekers passing by would be able to see actual jackpot winners and be inspired to come unto the gaming floor and play. Our stance is that this is no longer the case.
Many of the big name casinos today are massive complexes and you no longer can see inside from the sidewalk, so there is no longer a reason to put the ‘loose’ slot games close to any entrances.
Another classic rule is that loose slot machine games are located on the major aisles in the casinos, again so that more people could see winning jackpots and be motivated to play. Notably though, 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 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 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!
Today, casinos are constantly changing their philosophy about where to place the loose slots.
