Trusting Our Slot Reviews

Our team of gambling experts has been playing slots since the early days of online casinos. With our real money online slots reviews, you'll find the most generous RTPs (Return to Player percentages), best bonus rounds, and top jackpots.

We've also been gambling on the biggest and most popular land-based slots. Many of those top titles find their way into Internet casinos, and you can usually try games out for free first. We won't recommend lousy slots with poor payouts to you. We are interested in making real money, just like you, so all of our reviews come with a guarantee: these are MUST-PLAY games.

How Our Team Rates the Best

With our independent slot reviews, you'll find in-depth analysis of the best games on the net. Here's what we look for every time we load up a game:

Accessibility: Most modern online slots are available to play without download via a browser. We check to see which browsers are best, and whether the slots play well on mobile devices. All of our reviews feature games that are playable in HTML5 or Adobe Flash.

Gameplay: How do the reels spin? Are the graphics and animation up to speed? Can you set an Autoplay function, and is there a wide range of coin betting? These are all things we check off for you.

Bonus Games: Good 5-reel slots should have decent bonus features for discerning players. Free spins, Pick 'Em bonuses, and Trail Bonus games should be offered to help the bankroll grow. These shouldn't be detrimental to the volatility of the game, however.

RTP and Jackpots: All slots come with an RTP (Return to Player percentage) programmed in. The closer it is to 100%, the better it is for the gambler. We make sure the RTP is high enough to warrant a play, and also check that the jackpots are generous.

Volatility and Variance: When we compile reviews of the best online slot machines, volatility is a key factor. Volatility is the frequency of low and high wins. The more volatile a slot is, the less likely it is to pay out small and regular cash prizes. However, the big jackpots can be very good.

The Best Casino Websites: It's not just independent online slot reviews that we put together. We also make sure those slots are available to play at great Internet casinos. Our team makes sure all sites are properly licensed and regulated, have top security, and offer healthy welcome bonuses for slot players.

Read our online slots reviews and find a casino with your favorite picks. Then, get started and find yourself a top gaming site with a bonus to suit your budget.

Enjoying a Top Welcome Bonus

Slots casinos offer you generous bonuses just for signing up. You make a deposit and the casino will "match" it 100% or 200% if you play enough slots in your first few days. Typically, 100% of your slots gambling will be enough to get you that bonus you want.

A wagering requirement is a multiple of your deposit that must be cleared to earn free cash. So, for example, a 40x wagering requirement on a deposit of $100 means you will have to bet 40 x $100 ($4,000) to win $100 of bonus cash.

Progressive Jackpots

Progressive jackpots are massive prizes formed of small portions of each stake. They can keep on growing until they are triggered. Most slots have a special bonus game that is activated at random or by hitting a unique win line. The player must spin a prize wheel or play a Pick 'Em style game to win the jackpot.

With so many players gambling on progressive jackpot slots online, the biggest prizes sometimes far outweigh those found in land-based casinos. They are also won far more frequently. With our top independent online slots reviews, you'll discover some of the best progressive titles on the net.

Making the Most Out of Free Slots

Most online casinos have free-play versions of their slots. These credit the player with play tokens to enjoy, with no risk involved. Free-play slots are great for testing out gameplay, volatility, and bonus features.

Some casinos also have free cash bonuses where you earn real money for playing risk-free slots online. You'll find lots of free cash bonus offers at our top casinos. Read some of our online slots reviews, pick a casino, and start earning!

Choosing the Right Slots

There are literally thousands of online slots out there right now. That can be great for gamblers who want to try something new. But it can also be difficult to find the right games. No-one wants to waste time and real cash, after all. It's vital to play a variety of slots first before picking a few favorites.

Work out from the start if you want simple gameplay, low stakes, or generous bonuses. Perhaps you want a shot at a progressive jackpot. If that's the case, bring a large enough bankroll to handle the max bets and variance!
