Books have been set forth on this topic, and the debates and ruckus about where the "hot" video slots are installed in the casino are still ongoing – over 60 years after slot machine games were 1st placed in casinos.

The standard rule is that the most favorable slot games were located just inside the main entry of the casino; so that persons passing by would be able to see jackpot winners and be aroused to come into the casino and play. Our inclination is that this is definitely no longer so.

The majority of the mega casinos today are massive complexes … now you can’t see inside from the sidewalk, so there is no longer a reason to put the ‘loose’ slot machine games in close proximity to any entrances or exits.

An additional standard rule is that loose slot games are installed on the major aisles in the casinos, again so that more potential players could see winning jackpots and be galvanized to play. Importantly 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.
