Slot Machine positioning
Books have been stated on this topic, and the debates and ruckus about where the "hot" video slots are installed in the casino are still on-going – sixty years after the slots were first installed in gambling houses.
The quintessential rule is that the more favourable slot machines were installed just inside the main foyer of the casino; so that fun seekers going by would be able to see jackpot winners and be convinced to come unto the gambling floor … play. Our inference is that this is no longer the case.
Most of the mega casinos these days are mammoth complexes … it is not possible to see inside from the sidewalk, so there’s no longer a reason to put the ‘loose’ slots close to any entrances or exits.
Yet another traditional rule is that loose slots are placed on the major aisles inside the casinos, again so that more potential players could see winning jackpots and be roused 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 slot machine 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!
In recent times, casinos are constantly changing their perspective about where to place the loose slot machines.
