Books have been stated on this topic, and the contention and discussion about where the "hot" slot machines are located in a casino are still raging – sixty years after slot machines were first placed in the casinos.

The classic rule is that the very best slot machine games were placed just inside the entrance of the casino; so that potential gamblers walking by would be able to see jackpot winners and be convinced to come unto the gaming floor … play. Our inference is that this is definitely no longer the case.

Nearly all of the mega casinos these days are gigantic complexes … now you can’t see inside from the sidewalk, so there is no longer a reason to situate the ‘loose’ one armed bandits near to any doorways.

Another traditional rule is that loose slots are positioned on the major aisles in the casinos, again so that more potential gamblers could see winning jackpots and be influenced 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 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 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 machines.
