Books have been said on this topic, and the bickering and face-offs about where the "hot" one armed bandits are positioned in the casino are still raging – over 60 yrs after one armed bandits were first installed in gambling houses.
The classic rule is that the more favourable slots were placed just inside the entry of the casino; so that people passing by would be able to see actual jackpot winners and be attracted to come unto the gambling floor … play. Our sentiment is that this is no longer the case.
Nearly all of the major casinos presently are giant complexes and now you can’t see inside from the sidewalk, so there is no longer a reason to position the ‘loose’ slot games close to any doors.
An additional traditional rule is that loose slot games are put on the major aisles inside the casinos, again so that more potential gamblers could see winning jackpots and be inspired to play. Nonetheless, we find that this also is no longer a universal rule.
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!
Today, casinos are constantly changing their philosophy about where to place the loose slots.
