Books have been written on this item, and the conflict and squabbling about where the "hot" slot machine games are positioned in a casino are still raging – 60 yrs after the slot machines were first placed in the casinos.

The standard rule is that the most favorable slots were located just inside the main door of the casino; so that people walking by would be able to see jackpot winners … be stirred to come inside … play. Our interpretation is that this is definitely no longer true.

Many of the mega casinos these days are monstrous complexes … you can no longer see inside from the sidewalk, so there’s no longer a reason to put the ‘loose’ one armed bandits close-by any entrances or exits.

An additional classic rule is that loose slot games are put on the major aisles in the casinos, again so that more people could see winning jackpots and be motivated to play. Importantly however, 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 one armed bandits 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!

Nowadays, casinos are constantly changing their philosophy about where to place the loose slots.
