Best paying online slots
When playing slots at an online casino, it is important to choose a slot machine with the highest possible payout percentage. The higher the payout percentage, the better your chances of winning. The general term for the payout percentage of a slot machine is Return To Player. Often the abbreviation RTP is also used. The RTP indicates how much a slot machine eventually returns to the player.
If a slot machine has an RTP of 97%, then out of every 100 coins invested, 97 coins will be returned to the player. The casino would then make a profit of 3%, or 3 coins.
To get you started playing the best slots with the highest RTP, we have checked hundreds of different slot machines for their RTP. The result is below: a top of the best paying slot machines.
The slots sites guide
At the beginning we have already briefly discussed casino licenses. There are several other test criteria that a good online slot site meets. We use these criteria for each online casino test report. They cover all aspects and these evaluations give a good overall picture of the casino software provider. Transparency is very important, therefore we present the individual points in detail. They enable you to also independently assess the quality of an online casino.
In our experience, every player has different preferences and requirements for an online gambling website. One is looking for a high welcome bonus, another is looking for a specific payment method, a third for specific online roulette variants and a fourth wants a tiptop customer service. That’s why we give you a list of the best slot sites for each test category so that you can quickly and safely select the right provider.
1. Play only in secure slot sites
One of the most basic requirements of top slot sites is that they provide us with a safe gaming environment. But what does the safe mean? Casino providers must ensure fair gaming. An encrypted connection is also mandatory. Mechanisms for the protection of minors and responsible gaming are still among these criteria. The players’ money must be kept in a separate account. A valid casino license covers all these requirements. What they contain in detail and how they are guaranteed, you will find out in the next sections. I will also discuss the payout ratio, which is another marker for a reputable provider and a high value is a basic requirement for the best online casino slots.
Security is the most important thing in a slot site. You give the casino once your personal data and on the other hand your hard earned money. If you win in the games, then you should ensure that you get your winnings paid out. Unfortunately, in my experience, there are still black sheep in this area. Especially today, it is relatively easy for fraudsters to open an online casino. Therefore, caution is always necessary. Playing should also remain a fun, where you can still make cash with a little luck. Therefore, the option to set limits is mandatory to exclude from the outset a problematic gaming behavior. But now enough of words, let’s start and look at where a casino gets its license.
2. Trustworthy slot sites have a license
A casino license is the basis for safe and legally compliant gaming.
How to find out the validity of a casino license:
- Open the website of the casino
- Scroll down to the end of the website (footer)
- Look for the logo of the licensing office and find the licensing number
- Click on the number or copy it and go to the website of the authority
- Check if the license number matches the license data
- If you don’t find a license, ask the support for details
The most important licenses for casino players are:
- Malta Gaming Authority (MGA) – The majority of European online casinos have their headquarters in Malta. The small island state started early on to create a good environment for the providers.
- Gibraltar Gambling Commission – Due to its proximity to England, you will find mainly casino providers with English roots among the licensees. Due to legal uncertainties regarding the Brexit, however, some providers have moved to Malta.
3. Online slot site tested by independent agencies
The actual licensing is done by the governmental agencies. In order to ensure compliance with the licensing conditions, the authorities rely on external testing institutes. They ensure that the casino games are fair. How do they do that? They let them play countless times and determine a payout quota.
This test of the random number generators is one of the main tasks of the institutes. Furthermore, they control the compliance for responsible gaming and the protection of minors. But they also pay attention to IT security. Thus the secured connections are checked and the firewalls of the providers are tested. All in all, they are an important component for secure gaming in online casinos.
- eCOGRA – the internationally recognized test center for player protection has its headquarters in London. Founded in 2003, it introduced the first program for self-regulation in the online gambling industry. A seal from eCOGRA is a good marker for a fair and reputable online casino sites, not surprisingly you will find it on most of the slot websites.
- GLI – the Gaming Laboratories International are another constant when it comes to testing a casino. Founded in 1987, they test, among other things, the payout odds of the games and check whether all criteria for responsible gaming are met. Over the years, they have earned a worldwide reputation.
- iTech Labs – the tests of the Australian-based company are highly regarded worldwide. iTech Labs checks whether the gambling companies meet the requirements of the state licenses. They also offer as a service the creation of payout odds and check the IT security of the casino.
4. Slot site best payout rate
The payout ratio is an important aspect when choosing an online slot site. As you have already learned, it is determined by independent test institutes and recorded monthly. It indicates what percentage of the total bets are paid out to the players again. It is therefore not limited to a single game, but gives an overall impression of the odds of winning. In good slot sites, you will find this value indicated on the website, either directly or as a PDF download with all test data from the institute.
In addition to this total payout ratio, the best online casinos also give ratings for the individual games. The English technical term “Return to Player” is most common here and you will find it mostly in the abbreviated form RTP. Using an example, I would like to explain to you what it says exactly about a game. Let’s assume that the payout rate has a value of 98%. This means that if 100 €/$/£ is deposited, 98 €/$/£ will be returned to the players. Note that this is a theoretical value that applies to a large number of game rounds. In top online casinos these RTPs hardly differ from the total payout ratio. If you want to get an even better overview of the odds of winning, then also note the volatility of the games. A low volatility tends to mean more small winnings. A high volatility means less winnings, but bigger ones. An example of casino games with high volatility are jackpot slot machines.
