Picking a slot game that’s fun to play and looks good is important, of course, but many players ignore another crucial aspect. Each game comes with a different Return to Player, or RTP percentage. That number determines what percentage of the wagers is returned as prizes. The higher it is, the most generous a slot machine is.

If you want to improve your chances to win, as well as increase the value of all bonuses and promotions you are clearing, you should stick to the high RTP slots at online casinos. They can be a bit hard to find, so I decided to give you a hand.

You can find the game in plenty of online casinos, but I recommend you pick Betway Casino. It’s one of the best out there in terms of games, bonuses, and player safety.

Pay Dirt – High Payout Slot With Low Stakes

• Theme: The Gold Rush
• Sub-Category: Video slots, Progressive slots
• Developer: Realtime Gaming
• Casino: El Royale Casino
• RTP: 95-97.5%

Some people think that the highest payout slots online require large bets. That’s not really the case, as many games with at least solid RTP work with small stakes, and Pay Dirt is the best example among them.

This Realtime Gaming product is available to everyone because the lowest coin value is $0.01, and there are only 25 paylines. That means you can cover them all with a stake of $0.25 or even go for one only for $0.01, which is pretty much as low as it gets for video slots in 2020.

A bankroll of 10 or 20 bucks will be more than enough to enjoy Pay Dirt. The slot has a progressive jackpot, free spins feature, wilds, and scatters, so it provides plenty of exciting moments, too.

You can see for yourself by joining El Royale Casino, one of the best online that offer Pay Dirt in 2020.

Inferno Star – One of the Highest Paying Classic Slots

• Theme: Fruit
• Sub-Category: Classic slots
• Developer: Play’n GO
• Casino: Playamo Casino
• RTP: 96%

If you are looking for a classic slot that pays well and uses a simple gameplay system, Inferno Star is one of your best options. The game has only five reels and paylines and no side games, allowing you to focus solely on the reels.

The old-school sensation is completed by the fruit symbols, and there are some nice additions like re-spins, wilds, and scatters for additional fun.

If that sounds like a good slot for you, Playamo Casino is the best play to try it out in 2020.

At the Copa – High Payout Progressive Slot

Best Online Slots Casino Usa

• Theme: Night Clubs
• Sub-Category: Video slots, Progressive slots

Most progressive slots out there don’t come with a good return, but there are exceptions. One of the best of them is At the Copa. Betsoft’s game has an astonishing 97.5% RTP, which makes it the perfect choice for those who want to go after life-changing jackpots without losing too much in the process.

The design and symbols are also really enjoyable, and the betting limits are flexible. You can start low and go all the way up to $150 per spin. If you add the bonus game, the wilds, and the free spins feature, it’s easy to see why At the Copa is one of my picks for the highest payout slots online.

Find the Best Paying Slots Online

If you reached this post, I’m sure that you are one of the players looking for the highest paying slot machines online. My recommended game options are solid, and the casinos I’ve suggested all have plenty of games with a high RTP.

If you want to explore some other options, you can find some of them on our page dedicated to the best payout gambling sites. There are plenty of casinos there, but also other gambling platforms that are worth your attention.

Recent research shows us that online gambling has increased exponentially in popularity in recent years. The casino sites are in great demand and people can’t just get enough of it. Despite the variety of table games, card games, and bingo-like games, slot machines have remained the most popular among gamblers making up about 70% of online casinos’ revenue, you can check here to (see more).

The software developers are constantly creating new slots with new concepts and features just to monetize their popularity. Every week a new slot game shows up in the lobbies of gambling sites. But it’s almost impossible to know which slot machines are good, and which ones to avoid. You can’t spend days playing all available slots to find the one best.

Theoretically, it would take months even years to accomplish that. That is why we are giving you the ultimate guide to picking the best slots below.

Choosing online slots

Today the casino world offers thousands of slots. You are free to pick and choose the slots you prefer. If you choose to play for fun, there are movie-themed games like the Pirates of the Caribbean, Gladiator, and Superman. There are even cartoon-themed slots and rhyming verses.

Video games are another popular category of themed slots that includes classic titles such as Zuma, Tomb Raider, and Street Fighter. The new games like Call of Duty and Hitman also inspire game designers which are realized as parodies like Call of Fruity. Although the slots are visually stunning, they are not an important criterion in choosing a game to play. If you are playing to win real money you have to look for other tell-tale signs before choosing a slot.

Wagering options

Upon launching a slot game, you need to start with placing a bet. But it isn’t recommended you place whatever bet you want. Think carefully, and you will realize you don’t even know the betting options yet. Firstly, they all differ from slot to slot. This variety might confuse new players. So, let’s figure out what, how, and why we need to understand betting options.

Slot machines have a fixed minimum amount of bet available. Usually, it’s 1 cent per line. If you play a slot with 25 pay-lines, then the min bet is 25 cents per spin. That is why some slots, for example by Microgaming, have the option to choose the number of lines. You increase your total bet by increasing this number. However not all providers are like Microgaming, most of them either set a fixed number of 100 or 243 winning lines.

Return to player

If you are a frequent player you already know the importance of RTP, but if you are a newbie this information will be of great importance to you. RTP stands for Return To Player and it describes the amount a slot pays back to the players over a large number of spins, usually expressed as a percentage. The best winning slots usually have an RTP of over 95%, however, it’s not guaranteed that you will win a lot of money. Let’s look at an example if you place a $100 bet on a 95% RTP slot. Then your winning should be $95, and the other $5 goes to the house.

So, RTP is calculated over the whole lifespan of the machine. That means you can get a 120% return during your session, but another player might get only 85%. Your RTP depends on the number of bets made before you started spinning.

Volatility of slots

The concept of volatility appeared recently. It’s not common knowledge so there is a lot of misinformation out there. However, Volatility helps to establish your earnings as it explains the short-term fluctuation of the payout algorithm. You can make it work for you once you understand it.

Some games allow you to choose the level of volatility: low, medium, or high. The medium level applies to most slots. But the high and low levels are rare. High-volatility leads to massive jackpots and big wins. The flip side of these slots is the low frequency of winning outcomes. On the other hand, low-volatility games are a better choice for smaller jackpots and maximum winnings, since winning combinations appear more often than not.

High or low volatility?

It is recommended that you set a high level of volatility if you are likely to spend a lot of money on slots to make the most of it. This does not apply to regular players.

For a relaxed and fun-filled gaming experience, you can choose the low-volatility. So, you won’t have to spend too much time or money on winning these slots. But if your goal is to play all night long and win big, then the high-volatility level would be a smart choice. However, the RTP determines the total number of payouts and the volatility determines the number of spins.

Software developers

Of course, some experienced players usually play slots from their favorite developers. But in the beginning, you can set limits aside and play as many games as you want. Try several software developers to experience all the variations. With time, you’ll have more experience playing slots and then you can develop your winning strategy.

Free mode comes first

The best piece of advice for new players is to start by playing free games. Most casinos offer free games to every visitor. You are not even obligated to register. All you have to do is to launch the free slot and enjoy the game. This is the perfect way to learn gambling and understanding how it works.

Some casino sites also offer free bonuses to beginners. Usually, they offer a number of free spins or a small amount of money. Registration is mandatory to get these bonuses. You can play with the awarded money and even gain bonus cash to withdraw later.
