Looking for the best RTP slots is quite a hassle – most casinos do list it, but don’t give you the option to rank the games according to it. Many experienced players also have certain preferences towards the software studio that has provided the game. NetEnt, Microgaming and Playtech are the most recognisable and trusted brands, but there are also niche studios that have some hidden gems.

However, to be sure in the RTP that is published, it is important to play in a licensed casino that has passed all the necessary inspections for your region. As UK players, for instance, we always check the validity of the UKGC license for the casinos that we review on our website.

Down below, you can find the highest RTP slots we have found, and the rest of our top 10 – as well as links to casinos where the RTP is verified to be genuine and provide a 100% bonus on your first deposit and the max bonus can be as much as £300.

As you can see, there are quite many oldies and even some notable titles that couldn’t make the list of high RTP slot games, such as Kings of Chicago, Blood Suckers, Book of Dead, and Rainbow Riches, despite being great headlines with bonus spins and high variance.

There are new online slots coming out constantly, and we do try to keep our listings up-to-date, but the recent trend in slot games has been towards declining RTP levels – nothing has broken into our top 10 rankings since 2015.

You should also keep in mind that the RTP isn’t the only factor you need to consider when choosing among the best payout slots online for your session. Pro slot players are definitely aware of the detailed mechanics of slot RTP, but they also check other things like the variance of the game. Low variance and high variance can be a deal-breaker when combined with the best paying slot games.

What Is RTP and Why Is It Important?

The Return to Player rate is the favourite thing of all slot players – but what does it mean, exactly? If you like to hang out in land-based casinos, then you would hear about average RTP and house edge all the time. The RTP is a theoretical value that shows what portion of the total bets made into the slot will be returned in the form of winnings. Since the RTP is an officially published value, all slot machines have to pass a strict inspection whether their RNG engine complies with these values. In all our reviews, we always dig out the return to player percentage of the games and list it clearly.
