Books have been stated on this subject, and the conflict and ruckus about where the "hot" slot machines are installed in the casino are still raging – over sixty years after slot games were first added to the gaming floor in gambling houses.

The standard rule is that the very best one armed bandits were placed just inside the entrance of the casino; so that people walking by would see jackpot winners and be convinced to come unto the gambling floor and play. Our viewpoint is that this is no longer the case.

Many of the large casinos nowadays are massive complexes and you no longer can see inside from the sidewalk, so there is no longer a reason to position the ‘loose’ slot machines near any doorways.

Another standard rule is that loose slot machine games are put on the major aisles in the casinos, again so that more fun seekers could see winning jackpots and be galvanized to play. Importantly though, 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!

Today, casinos are constantly changing their philosophy about where to place the loose slot machine games.
