Volumes have been written on this subject, and the controversy and discord about where the "hot" slots are placed in the casino are still taking place – over 60 years after slot games were first placed in casinos.

The classic rule is that the best slot machine games were installed just inside the main entryway of the casino; so that folks going by would be able to see real jackpot winners and be enthralled to come unto the gambling floor … play. Our theorem is that this is no longer true.

Many of the big name casinos nowadays are immense 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.

An additional standard rule is that loose slot games are positioned on the major aisles inside the casinos, again so that more fun seekers could see winning jackpots and be roused to play. Notably 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 the 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 slot games.
