Books have been written on this topic, and the debates and interchanges about where the "hot" video slots are placed in the casino are still on-going – over 60 years after slot machines were first placed in casinos.

The quintessential rule is that the more favourable slot machine games were installed just inside the main entry of the casino; so that individuals passing by would be able to see jackpot winners … be drawn to come into the casino … play. Our standpoint is that this is no longer true.

The majority of the big name casinos today are herculean complexes … you no longer can see inside from the sidewalk, so there is no longer a reason to situate the ‘loose’ slot machines near to any entrances.

An additional standard rule is that loose slots are put on the major aisles inside the casinos, again so that more people could see winning jackpots and be influenced to play. Notably 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 slot games 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 philosophy about where to place the loose one armed bandits.
