Books have been said on this matter, and the controversy and feuds about where the "hot" slot machine games are positioned in a casino are still happening – more than sixty yrs after the slot machines were 1st installed in casinos.

The classic rule is that the most favorable slot games were placed just inside the main foyer of the casino; so that people going by would be able to see jackpot winners … be baited to come unto the gaming floor … play. Our observation is that this is no longer the case.

Almost all of the large casinos nowadays are herculean complexes … now you can’t see inside from the sidewalk, so there’s no longer a reason to put the ‘loose’ slot games close to any entrances.

Another standard rule is that loose slots are installed on the major aisles in the casinos, again so that more people 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 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!

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