Slot Machine positioning
Volumes have been set forth on this subject, and the contention and discourse about where the "hot" slot machine games are located in the casino are still intense – over sixty yrs after the slots were 1st installed in gambling dens.
The classic rule is that the more favourable slot machines were installed just inside the main doorway of the casino; so that persons going by would see jackpot winners … be enticed to come unto the gaming floor … play. Our observation is that this is no longer the case.
The majority of the large casinos these days are mammoth complexes and now you can’t see inside from the sidewalk, so there is no longer a reason to have the ‘loose’ slot machine games close-by any entrances.
Another traditional rule is that loose slots are located on the major aisles in the casinos, again so that more potential players could see winning jackpots and be galvanized 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 slot games 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 slot machine games.
