Books have been stated on this subject, and the debates and interchanges about where the "hot" slot machine games are placed in the casino are still there – over 60 yrs after slot games were first installed in the casinos.

The classic rule is that the better slot machines were located just inside the main foyer of the casino; so that everyone going by would see actual jackpot winners … be baited to come inside and play. Our disposition is that this is not so anymore.

The great majority of the mega casinos today are giant complexes and you can no longer see inside from the sidewalk, so there is no longer a reason to position the ‘loose’ slot machines in close proximity to any entrances.

Another traditional rule is that loose slot games are put on the major aisles inside the casinos, again so that more folks could see winning jackpots and be encouraged to play. Importantly 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 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 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!

These days, casinos are constantly changing their perspective about where to place the loose slot machines.
