Volumes have been written on this subject, and the bickering and face-offs about where the "hot" video slots are located in the casino are still on-going – more than 60 yrs after slot games were first placed in gambling houses.
The traditional rule is that the best slot games were put just inside the entrance of the casino; so that persons going by would be able to see actual jackpot winners … be enticed to come unto the gaming floor and play. Our thought is that this is definitely no longer the case.
Nearly all of the large casinos nowadays are super-colossal complexes and it is not possible to see inside from the sidewalk, so there is no longer a reason to position the ‘loose’ slot games close-by any of the doors.
Yet another standard rule is that loose slot machines are located 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 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 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.
