Books have been written on this topic, and the contention and disharmony about where the "hot" slot machine games are placed in a casino are still on-going – over sixty yrs after the slots were first placed in casinos.

The quintessential rule is that the very best slots were placed just inside the main door of the casino; so that potential players passing by would be able to see real jackpot winners and be convinced to come unto the gambling floor and play. Our presumption is that this is no longer the case.

Most of the big name casinos today are monstrous complexes and now you can’t see inside from the sidewalk, so there’s no longer a reason to place the ‘loose’ slot machines near to any entrances or exits.

An additional standard rule is that loose slots are located on the major aisles in the casinos, again so that more people could see winning jackpots and be inspired to play. Importantly however, 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 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 slot machine games.
