Volumes have been stated on this subject, and the controversy and feuds about where the "hot" video slots are installed in the casino are still passionate – 60 yrs after slot games were first added to the gaming floor in gambling dens.
The classic rule is that the more favourable slots were located just inside the main foyer of the casino; so that persons passing by would be able to see actual jackpot winners and be aroused to come inside … play. Our reckoning is that this is not so anymore.
Just about all of the big name casinos these days are mammoth complexes and you can no longer see inside from the sidewalk, so there’s no longer a reason to place the ‘loose’ slots close-by any entrances.
An additional standard rule is that loose slot machines are positioned on the major aisles in the casinos, again so that more folks could see winning jackpots and be energized to play. Notably however, we find that this also is not 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 one armed bandits 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!
In recent times, casinos are constantly changing their philosophy about where to place the loose slot machine games.
