Books have been set forth on this issue, and the conflict and ruckus about where the "hot" video slots are installed in a casino are still raging – more than sixty years after slot machine games were 1st added to the gaming floor in the casinos.
The traditional rule is that the best slot machine games were positioned just inside the entrance of the casino; so that potential gamblers going by would be able to see actual jackpot winners … be captivated to come unto the gaming floor … play. Our point of view is that this is definitely no longer so.
Most of the major casinos presently are jumbo complexes … it’s no longer possible to see inside from the sidewalk, so there’s no longer a reason to position the ‘loose’ slot machine games in close proximity to any entrances.
Yet another traditional rule is that loose slot machine games are installed on the major aisles in the casinos, again so that more potential players could see winning jackpots and be energized to play. Importantly however, 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 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 slots.
