The term ‘Vegas slots’ basically refers to high-quality, modern video slots. You won’t come across this term too often - many casinos simply refer to these slots just as ‘slots’ or ‘video slots’. The reason some call them ‘Vegas slots’ is because they’re designed to replicate the Las Vegas gambling experience. 

Of course, these slots are named after the desert gambling mecca of Las Vegas known for being one of the world’s top gambling destinations. It’s home to some of the largest casino resorts and has countless gambling opportunities available, including thousands upon thousands of slot machines. 

Online Vegas slots are intended to let players all over the world experience Vegas-style gambling for themselves. These slots are typically immersive and detailed, with high-quality graphics and sound effects, plus lots of exciting gameplay features.

These slots are based on the earliest version of slots: the physical slot machine, or fruit machine. This gaming machine had a large drum with three reels and a single row where you’d have to match symbols to win. There was also a large lever to the side that you’d have to pull to spin the reels. You would be surprised to find out that these games had some interesting slots strategy.

Over the years, these machines became more advanced, eventually incorporating video screens, before online slots started getting developed. Online versions of classic slots typically have just three reels and few, if any, special features; many of them are themed after fruit machines and have various fruits as symbols. Nowadays, games can be as grand as Conan slots - with multiple bonus features, free spins and 3D graphics.

Of all casino games, it’s the progressive jackpot slots that are responsible for paying out the highest cash prizes. What sets these slots apart from others is that they don’t have a set jackpot. Instead, their jackpots grow each and every time you place a wager. The more you wager and the more other players there are placing wagers, the more the jackpot grows. 

Since there’s no upper limit on the jackpot, it can get very high indeed. Some progressive jackpot slots wins, such as Microgaming’s Mega Moolah and NetEnt’s Mega Fortune, have been known to pay out eight-figure sums to incredibly lucky players. We suggest checking those out.

Most casinos offer a minimum of 150+ slots to choose from and the obvious question is - which ones should you try? Our Slot Review page has a list of popular games and has been reviewed by our team. Starburst, Rainbow Riches, Book of Ra and Narcos are just some of the slot game reviews you can find here.
