Find the top 20 slots with the highest RTPs—games with RTPs available for real money and some for crypto. Updated 24 Feb 2024 by Jack Bannon! (Images courtesy of Leon Casino & Spinmatic)
One of the ways most slot players try to minimise their losses is by playing online slots with the highest RTP. That makes a lot of sense.
Remember, RTP is actually ‘theoretical RTP’. That doesn’t mean a slot with a 98% RTP is going to pay back ₹-€-£-R 980 for ₹-€-£-R 1,000 you bet. However, in the long run, the theory is that a slot with a 98% RTP will give you a higher return than one with a 95% RTP—the reason for this variation.
Rather than go into more details about RTP and variation, you can find out more from our guide on Pay-out Ratios & RTP on Video Slots, and we have a guide covering slot machine variance.
So why did I decide to write this guide?. I thought it was time to see which slots had the highest RTP in 2024. Originally I wrote this in 2023, and just updated today on 24 Feb 2024. When I research for myself, as I am an online casino journalist, I also like to write about it here on Casinoplusbonus. So here we are.
The aim of my research came down to two simple questions. Are there any new slots in 2024 creeping into the top 20? Or has the list remained unchanged over the year? Also, which casinos can you play these online slots?
Well, we are about to find out. The research here will also catalyse future Highers RTP slot reports, which I intend to create. For example, the top 20 highest RTP cluster pays slots or the top 20 highest RTP Megaways slots. I can extend this list to the top 20 top-paying table games, virtual sports, and instant play games. As I add the lists of the top 10 and 20 slots for the various reel mechanics, I’ll also add them to this page and ensure those articles link back to this page so you have a circular reference of all the top RTP slot information.
Honest Research with No Shortcuts
I also made sure this is a 100% accurate top 20 list not copied from other sources on the Web. It seems many of the lists across the Web are exactly the same. The list I came up with is completely different, and as such, more accurate. I think the other sites just copy each other without researching correctly. One thing I don’t like is misinformation, so here you have a list create with honest research.
Why is the CasinoPlusBonus Top 20 Slots with the Highest RTPs Different? This is not a copy regurgitated from other gambling sites on the Web. Check for yourself. Almost every site claiming to show the top 10 or 20 highest RTPs does not give you an accurate overview. The slots in this report may surprise you. Therefore, these are the real top 20 slots in iGaming with the highest RTPs – researched with a lot of time and effort!

What changes were there to the Top 20 Slots with the Highest RTPs in 2024?
The addition of Ed Jones & Book of Bastet Deluxe Xtreme by Spinmatic came out this year slotting into what is in fact join third place with Book of 99 by Relax Gaming, and 3 Spinmatic online slots, which were Poseidon Xtreme!, Ed Jones & Book of Seth Xtreme, and Ed Jones & Book of Bastet Xtreme all released before 2024. There is also a newcomer coming to change to the Top 20 list in 2024 – Lucky Pets by Multislot.
Aside from the new 2023 entry of Ed Jones & Book of Bastet Deluxe Xtreme, so far as of 20 February 2024, the top 20 online slot with the highest RTPs has remained relatively unchanged.
RTP Sources – How I found and conformed these online slot RTPs
I mostly used casinos that host these games, like Leon, Goldwin, Beastino, and VooZaZa casinos, and used the search bar to find the game titles for various software providers. I also found other casinos hosting the games in the top 20 list. I have listed some of those casinos in the FAQ at the end of this guide, so you have a wide choice of platforms to choose from if you’d like to test these games out.
Here is the process I took:
- I searched the slot name using the highest RTP filters on various online casinos and made my lists.
- I then opened the slots and selected the ‘?’ to find the RTPs.
- I found the RTPs by scrolling through the info on this page.
- Once confirmed, I created my shortlist.
- I then organised slots in the table by highest RTP to lowest RTP on the top 20.
Play the demo and search for the RTPs yourself: Please feel free to use any of the rcommended casinos in the FAQ to play demo slots from the top 20 lists. P.S. You do not need to be a member to open the demo games on any of these platforms.

Why are some slots not available in all countries?
Some titles in the top 20 list are unavailable in all countries because some licensing authorities do not allow casinos to operate under their framework. See the bullet points below to see which countries each licensing authority covers. You can also learn more about licensing in ‘Step 2: Choose the Right iGaming Licensing’ on the best online casino advice page.
FAQs
Why is the CasinoPlusBonus Slots with the Highest RTPs in 2024 selection different from other sites?
Great question again. I can only speculate. Maybe the content editor just used the same lists from other websites and rehashed their lists. I went out there and researched the slots for the highest RTPs without using lists from other sites. This is my research with a bit of help from the team. You can check the slot demos and the RTPs in the information sections to confirm my research is correct.

Where are high RTP slots like Ugga Bugga and Mega Joker?
These two slots are often at the top of most online slots with the best RTPs lists. However, why they are in lists that say ‘in 2024’ is beyond me – it is a lack of research or ability to update their sites. These games are no longer available online. FYI Mega Joker had an RTP of 99%, and Ugga Bugga had an RTP of 99.07%. For some reason, NetEnt and Playtech removed them from their online slot game portfolios in 2021. I’m not bragging, but here at Casinoplusbonus, we are not copycats or sheep. We are providing current, up-to-date information.
