Volumes have been set forth on this topic, and the bickering and feuds about where the "hot" slot machines are placed in a casino are still taking place – more than sixty years after slot machine games were first placed in gambling dens.
The standard rule is that the more favourable slot machine games were installed just inside the entrance of the casino; so that potential players walking by would see real jackpot winners and be intrigued enough to come unto the gaming floor … play. Our attitude is that this is not so anymore.
The great majority of the big name casinos these days are jumbo complexes and you can no longer see inside from the sidewalk, so there is no longer a reason to put the ‘loose’ one armed bandits near any entrances.
Yet another standard rule is that loose one armed bandits are positioned on the major aisles inside the casinos, again so that more potential gamblers could see winning jackpots and be influenced to play. 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 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 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.
