Volumes have been written on this topic, and the controversy and ruckus about where the "hot" slot games are positioned in a casino are still on-going – sixty years after slots were first placed in casinos.
The quintessential rule is that the more favourable slot games were placed just inside the main door of the casino; so that casino fanatics passing by would be able to see jackpot winners and be enthralled to come into the casino … play. Our assurance is that this is definitely no longer so.
Many of the big name casinos nowadays are immense complexes … it is not possible to see inside from the sidewalk, so there’s no longer a reason to place the ‘loose’ slot machine games in close proximity to any entrances.
An additional classic rule is that loose slot machines are placed on the major aisles in the casinos, again so that more folks could see winning jackpots and be motivated to play. Importantly however, 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!
These days, casinos are constantly changing their perspective about where to place the loose slot machine games.
