Volumes have been written on this item, and the debates and arguments about where the "hot" slot machines are located in a casino are still taking place – more than sixty yrs after slot games were first placed in gambling houses.
The quintessential rule is that the very best slot machine games were located just inside the main foyer of the casino; so that individuals going by would see actual jackpot winners and be baited to come into the casino … play. Our opinion is that this is definitely no longer the case.
Many of the large casinos nowadays are humongous complexes … it is not possible to see inside from the sidewalk, so there’s no longer a reason to situate the ‘loose’ one armed bandits in close proximity to any doors.
Yet another traditional rule is that loose slots are put on the major aisles inside the casinos, again so that more fun seekers could see winning jackpots and be influenced to play. Nonetheless, 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 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!
Nowadays, casinos are constantly changing their philosophy about where to place the loose slot games.
