Books have been set forth on this matter, and the controversy and interchanges about where the "hot" slot games are installed in the casino are still taking place – over 60 years after slot machine games were first added to the gaming floor in gambling houses.

The classic rule is that the more favourable slot machines were placed just inside the main door of the casino; so that everyone going by would be able to see actual jackpot winners and be stirred to come unto the gambling floor … play. Our resolve is that this is definitely no longer true.

Most of the big name casinos nowadays are mammoth complexes … you can no longer see inside from the sidewalk, so there is no longer a reason to situate the ‘loose’ slot machines in close proximity to any doorways.

Another classic rule is that loose slot machines are located on the major aisles inside the casinos, again so that more persons could see winning jackpots and be encouraged 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 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 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 games.
