Volumes have been set forth on this issue, and the controversy and ruckus about where the "hot" slot machines are positioned in the casino are still rampant – 60 yrs after slots were 1st placed in casinos.
The quintessential rule is that the superior slot machine games were positioned just inside the main entry of the casino; so that potential players passing by would be able to see actual jackpot winners and be infatuated enough to come into the casino … play. Our slant is that this is definitely no longer the case.
Most of the mega casinos presently are mammoth complexes … you no longer can see inside from the sidewalk, so there’s no longer a reason to situate the ‘loose’ slot machines near to any entrances or exits.
An additional classic rule is that loose slot machine games are located on the major aisles in the casinos, again so that more potential gamblers could see winning jackpots and be influenced to play. 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 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!
In recent times, casinos are constantly changing their philosophy about where to place the loose slots.
