Books have been set forth on this item, and the controversy and disharmony about where the "hot" slot machine games are installed in a casino are still taking place – more than sixty years after slot machine games were 1st placed in casinos.
The traditional rule is that the better slot machine games were placed just inside the main entry of the casino; so that people going by would be able to see real jackpot winners and be stirred to come into the casino … play. Our assessment is that this is no longer true.
The great majority of the mega casinos presently are titanic complexes and it’s no longer possible to see inside from the sidewalk, so there is no longer a reason to situate the ‘loose’ slot machines near to any doorways.
Yet another standard rule is that loose slot machine games are installed on the major aisles inside the casinos, again so that more persons 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 one armed bandits 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.
