Ranking Methodology: How We Found The Best Online Slots Sites 

Popularity in the market 

One of the things we always look out for when choosing online casinos is how popular they are with other players. Popularity is a huge seal of approval. The more people that enjoy a slots site, the more trust we have in it. 

Payout percentages 

Payout percentages is a key criteria because it increases your chances of winning. We looked far and wide to find the sites that had the highest paying slots so that you can get more bang for your buck. 

User-friendliness 

The best slots sites are user friendly and easy to play on. We wanted to find sites that are easy to navigate, and which are easy to get to grips with. This means zero hassle and no need to constantly have to contact customer support for help. 

Variety of available online slot games

Slots are more fun when there are lots of different online slot games available. We looked for sites that offered a good selection of games with lots of variety, ranging from TV and moved-themed games, adventure games, progressive jackpots, and more. 

Site trustworthiness 

Before finalizing our list of online slots, we made sure to check things like SSL certificates, online reviews, and licenses. This helped us dump untrustworthy sites in favor of those that offer reliable payouts and won’t suddenly “go rogue” and disappear. 

Loyalty and bonus programs 

Loyalty and bonus programs are important for a fantastic all-around experience at a slots site. They top you up with lots of perks during your stay, such as free spins, cashback offers, and sometimes even free cash. This is why we made sure to find sites that offer eye-catching loyalty programs. 

Secure and legit payment providers 

We know how important it is that you’re able to bank with confidence at any gambling site you sign up to. We also know how easy it is to get scammed online. As such, we looked for sites that offered secure, legit, and recognizable payment providers, as we believe this to be a massive sign as to how credible a slots site is.

What The Best Slots Casinos Offer

Slots casinos are just great fun. But what do the best slots casinos offer that helps them stand out from the not-so-best ones? 

Here are some features to look out for: 

Free Spins 

Free spins are a popular bonus offered by the best slots casinos. The number of free spins you get varies, but usually, you can expect to receive between 20 and 50 of ‘em. They must be used on specific games, such as Starburst at Ignition, and some sites even offer free spins as part of the welcome offer.

Keep an eye out, though, because free spins are usually dished out randomly during your stay with a casino! 

Deposit Bonus 

A deposit bonus is basically a welcome offer that requires you to make a deposit before you can grab the bonus. Because it’s what’s also known as a “real money” bonus, wagering requirements are typically low, which means you don’t need to gamble too much of your own money before any winnings are yours to withdraw. 

No Deposit Bonus 

With the no deposit bonus, you don’t have to deposit any of your own money before you can play! Only available at select casinos, including Ruby Fortune, this slots bonus is a big winner among beginners because it’s basically a free bet. 

However, because it’s a no deposit bonus, this type of offer usually comes with steeper wagering requirements. In other words, you’ll still need to eventually play with some of your own cash before you can withdraw any winnings. 

Free Slots vs. Real Money Slot Games 

When you sign up to slot sites, you’ll find that the best ones offer you a choice between free slots and real money slot games. They have different names, but they’re both a lot of fun. So what’s the difference?

Free Slots

Free slots are essentially demo games. You get to play with “credits,” but you’re not playing with real money. As a result, you won’t win any money. All you will build-up is more credits. 

Why play free slots? 

Free slots are perfect if you’re a bit bored and have no wish to spend any of your own money. They also let you be bolder with your gaming choices, and they also represent a chance to develop and fine-tune your strategy. 

Real Money Slots

Real money slots are the standard slots you’ll find on slots sites. These are the classic ways to win lots of REAL money when playing slots. With often huge jackpots, real money slots are thrilling and exciting – but the risk is that you could also lose your own money. 

For many, though, that’s just part of the entertainment, and playing real money slots gives you the full online slots experience. And if you’re lucky, you may just win big, and you may also get to use free spins now and then, too. 

Slots Strategy: How To Play Slots Online 

There are some recreational gamblers who will tell you that slots is pure luck. Whether you win or lose, it’s all in the lap of the gods. 

There are others who’ll tell you the opposite and that the key to win slots is to have a slots strategy. 

Playing Style 

Before you begin playing for real money, you should decide on a playing style. It doesn’t matter if this is the style you maintain the entire time because you can experiment as you go along, but it’s important to start off with a style and see if you can hone it. 

For example, a popular slot-playing style is the pattern strategy. With this slot-playing style, you need to decide on a set of patterns of bets before you begin a game, as well as a pre-arranged sequence of wagers.

For example, one such example of a pattern slots strategy is a sequence of 15 bets that go 1-1-1-2-2-2-3-3-3-3-2-2-2-1-1-1 and uses twenty-seven coins. At the end of the sequence, set your winnings aside and start again. 

If, however, you lose 3 times on the spin on an online slot at the end of three sets of the same pattern, try another game.

Bankroll Management 

Bankroll management is a key element to successful online slot machines. If you haven’t decided how to manage your bankroll, your losses could be very heavy – and even impossible to recover from. 

We recommend deciding on a bankroll before choosing a unit size for each wager. For instance, each time you play the slots, you could wager 1-3% of your bankroll. Or, if you’re more aggressive, you might want to set aside as much as 5%. 

That all said, you can tweak your bankroll throughout your slots career. If you manage to pile up the wins, you might want to increase your bankroll.

Game Types 

Lastly, there are many different types of slots. Each one has a different gameplay style, as well as different RTPs. You need to find the game types that are most comfortable for you before playing for real money (this is why it’s always a good idea to find free slots games first, such as those at Ruby Fortune).

Types of slots include:

• 3 reel classic slots
• 5 reel slots
• Progressive slots
• Mobile slots
• Mega spin slots
• Multi payline slots
