Volumes have been stated on this item, and the controversy and discourse about where the "hot" slot games are located in the casino are still taking place – over sixty years after slot machines were 1st placed in the casinos.
The standard rule is that the most favorable slot machines were positioned just inside the entrance of the casino; so that fun seekers walking by would see real jackpot winners and be keen enough to come unto the gambling floor and play. Our philosophy is that this is no longer true.
The great majority of the mega casinos these days are oversized complexes and it is not possible to see inside from the sidewalk, so there’s no longer a reason to have the ‘loose’ one armed bandits near to any entrances.
An additional traditional 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 roused to play. Importantly though, we find that this also isn’t 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 slots 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 perspective about where to place the loose slots.
