RTP Guides (Return to Player Database)


!!! The biggest RTP database on the planet !!!

Definition: Return to Player (RTP) is the phrase casinos and casino games makers use to describe the long term expected payback percentage from all wagers on a slot machine, video poker machine, video lottery terminal (VLT), pokies or any other form of gambling with a set calculated house edge. Using a simple example, if you were to make a thousand one euro bets on a slot machine on with a theoretical RTP of 95%, all other things being equal you would expect to get a return of €950 in wins from your staked €1,000.

Knowing your percentages is absolutely key in an online slot players strategy. Why play a slot which has a 10% house edge when you can play a slot which has a 3 or 4% house edge instead. For this reason we are going to be compiling exhaustive lists of RTPs from the leading slot designers. We will be listing these on this page. Making these lists is very time consuming so bear with us while we work our way through making new ones and keeping existing ones up to date!

Massive thanks to those slot providers who have been kind enough to send us their information and/or complete lists!

Online Slots RTP Hall of Fame

You are encouraged to check out our RTP database for all the best and worst paying online slots. But here we have taken a selection of some of the best paying slots for our little hall of fame!

[Read the full article]


Please note that there can occasionally be variance in the theoretical return to player based on the number of lines you are playing or the selections you make. The RTP percentages are also calculated over millions of spins rather than hundreds. The data tables should therefore be only taken as a guide.

Return To Player (RTP) Guide

One slot machine or 500 slot machines?

We have already discussed the random number generator and based on years of experience we can take the casinos word that it doesn’t technically matter much which slot you actually play at any given moment (with regards hitting jackpots, having winning or losing runs, etc). You can also check this out yourselves by viewing your game history over a few different slots and checking the game ID’s.

The problem many rookies make is after hitting a big win on one slot, they avoid this slot but use their winnings to play bigger stakes on other slots within the same online casino. Or by using the winnings from one slot to try and chase previous losses on another slot. For all intents and purposes, all individual slots within an online casino can be viewed as one giant slot, just with various different interfaces. Online slots and casinos should never be compared to land based slots and casinos.

Not all online slots are created equally.

Despite what we have just explained, you still need to differentiate between the individual slots within any online casino. While the RNG will generate a winning or losing number for all the slots, the individual payouts can differ greatly.

You can find out the theoretical payout percentages a.k.a. “Return to player” a.k.a. RTP for most slots via one of the menu, help, question mark etc buttons within the slot games themselves.


We are fans of the Marvel Jackpot slots provided by Playtech. We know that a few casino sites are anti-Playtech and anti-Marvel (the cynic in us says this may well be because Playtech casinos generate very little revenue for affiliates) but as with any form of gambling you need to be aware of what you are doing (We have discussed the Marvel slots in more detail in a later article).

Playtech casinos all list the same RTP for a particular slot, even if they are not even part of the same casino chain. And Playtech makes these RTPs very easy to find and compare. Simply click on “help” within any Playtech slot and you will have a pop-up window where you can find details about all the slots on offer at that casino. (For Net|Ent slots, another major player in the online casino game, you click on the question mark to find the relevant information. On you can even practice pretty much all of their slots portfolio).

Progressive jackpots usually have lower RTPs to non-jackpot slots because a small percentage of every spin is set aside for the jackpot(s).

Here then are the RTPs from a few popular Playtech slots: Iron Man 2 – 25 Lines (95.98%), Iron Man 2 – 50 Lines (92.31%), Hulk – 50 Lines (91%), Everybody’s Jackpot (94.01%), Desert Treasure (97.05%). So all things being equal (if the slot pays exactly the RTP during the test), playing 5000 spins at €1.00 you could expect to lose €450 on Hulk 50 Lines but only lose €147.50 on Desert Treasure.

Another valuable note is that if there are two variants of a Playtech Marvel Jackpot machine, it appears that the 50 line version always has a far lower payout percentage than the 20 or 25 line version .

Our rule is very simple: “Always check the RTPs before playing any slot”.
