Books have been written on this item, and the conflict and interchanges about where the "hot" slot machines are positioned in a casino are still ongoing – 60 years after the slot machines were first installed in gambling houses.

The quintessential rule is that the more favourable slot machine games were put just inside the door of the casino; so that individuals going by would see real jackpot winners … be enticed to come inside and play. Our conviction is that this is definitely no longer true.

The great majority of the major casinos today are massive complexes … now you can’t see inside from the sidewalk, so there is no longer a reason to place the ‘loose’ slot games close to any doors.

An additional standard rule is that loose slot machine games are placed on the major aisles in the casinos, again so that more persons could see winning jackpots and be roused 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 the slots 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 perspective about where to place the loose slot machines.
