Volumes have been written on this item, and the controversy and ruckus about where the "hot" slot machine games are positioned in the casino are still bubbling – more than 60 yrs after the slot machines were first added to the gaming floor in casinos.
The standard rule is that the better slot machines were positioned just inside the main entry of the casino; so that fun seekers walking by would see jackpot winners … be drawn to come inside … play. Our inclination is that this is definitely no longer so.
Almost all of the large casinos nowadays are mammoth complexes and you no longer can see inside from the sidewalk, so there is no longer a reason to place the ‘loose’ slot machine games near to any entrances or exits.
An additional standard rule is that loose slot machines are located on the major aisles in the casinos, again so that more people could see winning jackpots and be motivated 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 slot machine 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 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 machine games.
