Books have been stated on this item, and the bickering and discord about where the "hot" slot machines are located in the casino are still on-going – more than sixty years after one armed bandits were 1st added to the gaming floor in gambling houses.
The standard rule is that the most favorable slot games were put just inside the main entry of the casino; so that persons going by would be able to see jackpot winners … be intrigued enough to come unto the gambling floor and play. Our determination is that this is not so anymore.
Most of the big name casinos presently are titanic complexes … now you can’t see inside from the sidewalk, so there’s no longer a reason to situate the ‘loose’ slot machine games near to any exits.
Yet another classic rule is that loose slots are located on the major aisles in the casinos, again so that more fun seekers could see winning jackpots and be energized to play. Nonetheless, 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 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 philosophy about where to place the loose slot machine games.
