Slot machines are the backbone of the casino operation in Las Vegas. We play them knowing the odds aren’t in our favor but crave the next bonus or quick hit. With the popularity of slots, why not throw together a list of fun facts?


  • There were 38,743 individual slot machines on the Las Vegas Strip in 2017 according to NV Gaming Control Board Revenue Reporting (All Non-Restricted Locations).


  • There were 9,753 individual slot machines in downtown Las Vegas in 2017 according to NV Gaming Control Board Revenue Reporting (All Non-Restricted Locations)


  • The outcome of a spin on a modern slot machine is determined by a random number generator (RNG) at the time you pull the lever/press the button to spin. The reels simply move to the pre-determined position on the screen to match the RNG’s output. The RNG is always kicking out numbers, when you push to spin you “lock” the combination that will determine your fate. Scrap your dances, rituals and rubbing the screen – Just press that button at the right time!


  • Because the RNG is 100%, random, each spin is an individual event. The slot machine is unable to “go cold” in order to win back money paid out by the machine. Player slot odds are the same on each and every spin.
