How We Track Real Slot RTP Across Every Casino

We built this site around one problem: the same slot pays out different RTPs at different casinos, yet nobody publishes this data. All the figures published on this site have been verified live in the game.

Why this site exists

Casinos decide which RTP a slot will use when they deploy it. Game developers usually offer several different RTP percentages for the same slot game, ranging from 92% to 97%. The casino chooses which percentage to use. Nobody seems to know which RTP a slot is using when it is being played.

We have encountered significant gaps in RTP percentages for the same slot game, with the best percentage from one casino being 4.17% higher than the worst percentage offered at another casino. This is avoidable if individuals understand where to find this information.

TopPayingCasino.com was built to publish this information and keep it up to date.

Our verification method

Every RTP percentage listed on our website was obtained in the same way:

Load the game at the casino using a real account in the relevant jurisdiction.

Click on the game information screen (help screen) to view the RTP percentage for the game.

Note the RTP percentage of the slot game that is displayed on screen.

Refer to the game rules to verify the RTP percentage of the game noted above.

Repeat steps to re-verify. The RTP percentage can change. We verify the percentage whenever we deploy the game and whenever we notice a change to the percentage at a casino.

All of the RTP percentages that are published on this website are obtained directly from the slot games at the online casinos. We do not use any third parties to obtain these figures.

What we are not

✕We are not a bonus comparison site. We do not rank casinos by welcome offers.

✕We are not a slot review site. We do not score games on volatility feel or theme.

✕We do not publish unverified RTP data or pull figures from developer websites without in-game confirmation.

✕We do not accept payment to change RTP figures or casino rankings. Commission earned through affiliate links does not influence the data we publish.

Affiliate disclosure

This website contains affiliate links. When you click on one of the calls to action (CTA) for a casino and sign up for an account with them, we might earn a commission from that casino. The casinos pay the commission; it does not affect the price of the software or services that they offer. The RTP data on this site is verified before and after any commercial relationship with these casinos.

All of the affiliate links on this website route through /go/[casino-slug]. The direct affiliate links for the casinos are not embedded in the web pages. The casinos are included on this website based on their ability to offer high RTP percentages for their slot games, not based on their ability to pay us a commission.

Coverage scope

Right now, we verify the RTP percentages for 14 different slot games at 10 different online casinos. All of the casinos that we cover are licensed online casinos and offer popular slot games from providers such as Pragmatic Play, Hacksaw Gaming, Play'n GO and ELK Studios.

New slots will be added to our database whenever we have verified the RTP percentages for all of the casinos that we track. New casinos will be added to our database whenever they gain a license to operate online casinos in a major jurisdiction.
