They’re also some of the biggest slot machine winners! Old casinos with older slot machines and smaller crowds have notoriously loose slots. Circus Circus, Bally’s, and Paris Las Vegas are 3 of the oldest, least impressive casinos on the Strip. If you’re intent on sticking to the Strip, stay away from the newest, most luxurious casinos. Head to the Boulder or North Las Vegas areas to find smaller casinos with fewer crowds and loose slot machines! Slot machines that aren’t on Fremont Street or Las Vegas Blvd have some of the best odds, but it’s a bit of a drive to get there. Fremont Street is the most popular downtown gambling destination, but don’t be afraid to go off the beaten path. The Las Vegas Strip is the city’s busiest area, and the slot machines and casino operators are known for being tight, especially during busy weekends. The first piece of advice you need to follow if you’re looking for loose slot machines is to get off the Las Vegas Strip. Certain areas will increase your odds of finding the loosest slots and winning big, though! Unfortunately, there’s no way to know which machines are the loosest slots. In other words, many consider these to be the best slot machines. What does that mean, though? For a slot machine to be considered loose, it will pay out more often or in higher amounts than other slot machines. There’s a popular myth among gamblers that some slot machines are looser than others.
