Books have been set forth on this subject, and the conflict and squabbling about where the "hot" slots are installed in a casino are still there – over 60 years after slot machines were first installed in casinos.
The standard rule is that the best slot games were located just inside the main entryway of the casino; so that individuals walking by would see actual jackpot winners and be tempted to come unto the gaming floor and play. Our assessment is that this is definitely no longer true.
Practically all of the major casinos today are huge complexes and you no longer can see inside from the sidewalk, so there’s no longer a reason to position the ‘loose’ slot machines in close proximity to any exits.
Another traditional rule is that loose slot machines are put on the major aisles in the casinos, again so that more people could see winning jackpots and be energized to play. Importantly though, we find that this also is no longer a universal rule.
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!
These days, casinos are constantly changing their philosophy about where to place the loose slot games.
