Every player’s relationship with online casino slots is defined by many factors. Do you like what you see or do those shiny graphics tire your eyes? Is the game running smoothly both on your desktop screen and on your mobile device? Are you enjoying the sound of the background and the effects, or are they boring? Do you like winning often, or do you prefer winning big? Don’t be shy, admit it. On the bottom line, it’s all about winning and many gamblers seek the highest RTP slots.

The games RTP percentages, show the payout ratio, the amount you can expect to get back for every coin you wager. The Return To Player (RTP) is given in percent. The casino average RTP, no matter if its an experienced provider or a new casino, is around 96%.

We are talking, of course, about online casino providers, not land-based casinos, on which the payout percentage is significantly less. In some occasions, real money casinos besides promoting their bonus features, are also promoting an above-average RTP percentage.

What is RTP in slots?

But BetandSlot’s experts present you with the games and the online and mobile casinos that are really way ahead of their peers. Therefore, there is no reason to hesitate long to try these video slots yourself. More and more new slots are more towards the average and therefore this list will probably continue for a long time.

The return to the player ratio is the amount you can expect to get back for every euro you wager. Of course, this is only theoretical, and sometimes you can be very lucky and win a large sum after just a few turns. Or you lose a lot of euros, even though you have been playing for quite a while.

What are the best slot machine games with the highest payout ratio and where can I play them – perhaps combine them with a casino bonus or some free spins ? In this list, you will find the best online slot games to win, the highest RTP slots 2019 and of course the highest RTP slots 2020!

1. Ugga Bugga, 99.07% – Playtech

Ugga Bugga

Playtech brings us the absolute highlight of this list. Ugga Bugga is a slot where you have almost nothing to lose because you get back more than 99 cents for every euro you spend.

Of course, this is only theoretically, since you can still be unlucky sometimes, there are no guarantees! Ugga Bugga is an interesting slot and has the highest return to player percentage!

You play on 10 different pairs of three with symbols. You spin the first one and you then have the option to hold one to three of the symbols and place them on all other reels. Only then you will spin all other reels and see what your winnings are. You need a little understanding, but you should give this great RTP slot a chance, although it’s not so easy to find it anymore, even among online casinos which are working with Playtech!

2. Mega Joker, 99.00% – NetEnt

Mega Joker - NetEnte

In addition, the classic also offers a maximum profit of a whopping €30,000. You really shouldn’t think twice about trying the game yourself.

Ooh Aah Dracula – Barcrest

The 99s club continues with a humorous take on the story of the most fearsome of all Barcrest vampires. 

This slot has a slightly crazy Dracula theme – and lots of interesting features with it. This title is a step up for Barcrest. Hectic music and cartoon-like symbols are combined to make this a cheerful look at the otherwise dark Dracula theme.

8. Jackpot 6000, 98.90% – NetEnt

Jackpot 6000 - NetEnt
Jackpot 6000 – NetEnt

The classic Slot Jackpot 6000 from NetEnt is not only by far the most popular slot in Norway, but can also impress us with an RTP that still scratches at 99%.

Jackpot 6000 is the classic online slot machine with 3 reels and 3 rows of symbols. In this game there are 5 fixed paylines. 

The symbols you can step on the reels during the game are very traditional for classic machines, pictures. These are stars, bells, grapes, lemons, cherries and jokers.

Although the free Jackpot 6000 slot is classic, there are bonus games here. The bonus game is called “Supermeter”, it can start after any winning round. Any combination of two symbols can bring you the additional price. There is also a gambling feature here that can double your winnings.

We cannot escape this fascination and this profit potential and neither should you. Instead, you can try it yourself.

11. Jokerizer, 98.00% – Yggdrasil

Jokerizer - Yggdrasil
Jokerizer – Yggdrasil

The up-and-coming and now very successful Studio Yggdrasil understands something about high RTP slots and Jokerizer sends a candidate into the race that excellently combines classic design with modern features.

Yggdrasil slot machines are lovely and always of high quality. Every game from this provider is a masterpiece that consists of exciting functions and a beautiful design.

Kings of Chicago - NetEnt
Kings of Chicago – NetEnt

With Kings of Chicago, NetEnt has a small unique selling point in the slot segment. Because this slot combines classic slot machine action with video poker elements. 

The whole layout of the slot machine is reminiscent of a poker table. It is a is 5-reel, 3-row, 5-payline video slot. The payline are the three straight row and two V shaped lines running from the corners. 

The first thing that is close to poker is the way the symbols appear on the reels. The reels don’t spin, so each time the cards are divided into five columns and three rows. The existing game symbols include all playing cards, that is 52 cards plus jokers. 

Natural royal flush gives the player the best pay off that is worth 10,000 coins. Five of a kind (4 plus wild card) give 1,500 coins. Enjoy this online video slot at Slotnite casino.

14. 9K Yeti, 97% – 4thePlayer

9k Yeti - 4theplayer

There are also video slots with low RTP, sometimes even below 90%. Caution here. Often these are progressive jackpot slots, like Mega Moolah, which has an RTP percentage close to 90%. But, those Jackpots have such an enormous potential for profit only if the jackpot is hit, and as you know that doesn’t happen so often.

But today we want to deal primarily with the highest online slots RTP percentage, with those slot games that have a particularly high payout ratio bigger than 97,5% and up to 99,2%. 

Even King Cashalot from Microgaming comes with a 90.45% RTP, close to other popular slots like One Million Reels BC from Rival Gaming (90.6%), 2 Million BC from Betsoft (91.64%) and Novomatic’s Book of Ra (92%). Poor RTP’s, don’t mean poor games, and those popular titles are the proof.

It doesn’t hurt, for example, to know the best online slots payout percentage and to select the most lucrative games. While experts know that every slot machine differs from others in terms of the return to the player ratio, among other things, most beginners are in the dark in this regard.

The RTP ratio on slot machines is the part of the stake that is paid back to the player in the long term. Some compare the pay off ratio with the so-called house edge. However, the house edge is only part of the actual payout ratio.

Anyone planning a long-term commitment should not underestimate the payout ratio. If this is low, the chances are slim. If it comes close to 100 percent, the player can really hope for long-term profits if they are lucky.

Casinos game’s RTP under test

There is a mathematical algorithm powering every slot game. This mathematical machinery spitting out results is by no means monstrous, but rather a random generator that generates game results. Long-term tests then result in the so-called payout ratio. Put simply, a slot with an RTP of 95% pays back an average of 95 euros if 100 euros were bet.

In the gaming scene there are some companies that regularly dedicate themselves to a particular slot or several slot machines and put them through various tests. These include, for example, the companies eCogra, iTech Labs and GLI. They are independent auditors that check slot machines for fair play and a correct RTP ratio.

Top5: Popular slots with high RTP percentage

Except the above-mentioned slot games with really impressive RTP, we should also comment the pay off percentages from the most popular slot games in the market.

Starburst - NetEnt

  • Starburst from Netent for example, has a 96% which is decent. But Starburst impresses with its arcade feeling, exciting and fast gameplay on 5 reels and attractive chances of winning including a 50,000 euro jackpot. The spacey soundtrack does the rest.

Classic table games with the best payout percentages

Even classic casino games like blackjack have some variants with an extremely high payout ratio. Often, players can also increase the pay off percentages in these games by mastering all the rules of the game and being able to use advanced strategies.

Blackjack

Blackjack comes in many different variations. Most blackjack variants have a very low house edge, which is often less than 1 percent. Blackjack games with a particularly high RTP ratio are Classic Blackjack (Single Deck), Double Exposure Blackjack, and Switch Blackjack. Check out the Blackjack cheat sheet and increase even more your winning chances.

Casino Hold’em

Also, Casino Hold’em has a relatively low house edge and therefore a high RTP percentage. With in-depth knowledge of the casino game, moves can be analyzed and the best move for that moment can be found. In the same turn, the house edge decreases further.

Pai Gow

Pai Gow poker online is a special variant of the popular card game poker. Online Pai Gow basically has a very low house edge of 1.46 percent and thus a payout ratio of over 98.5 percent.  

Online casinos guarantee their customers a lot of fun. However, if you are familiar with the RTP rates, you will also have an eye on it. We recommend that you consider the RTP percentage of a slot game before playing. So, you will have a greater chance of long-term winnings.
