Books have been written on this item, and the bickering and feuds about where the "hot" slots are positioned in a casino are still there – more than sixty yrs after slots were 1st installed in the casinos.
The classic rule is that the better slot machine games were placed just inside the entry of the casino; so that folks walking by would see real jackpot winners … be aroused to come into the casino … play. Our standpoint is that this is no longer true.
Most of the large casinos these days are jumbo complexes and it is not possible to see inside from the sidewalk, so there’s no longer a reason to situate the ‘loose’ slot machine games near any doors.
Yet another standard rule is that loose one armed bandits are located on the major aisles inside the casinos, again so that more potential players could see winning jackpots and be energized 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 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 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 machine games.
