This page aims to provide you with all the information on which slots pay the most and have a high RTP.
As we will better discover in this review, the Return to Player (or RTP) is a fundamental data to understand a slot at non GamStop Casinos, but since there are many “families” of these software it is worth pointing out those with the highest percentage values in relation to each category. The following is a sort of Top 5 that includes all the major categories at top-rated non GamStop casinos in the UK.
How Is RTP Determined at Non GamStop Casinos?
To determine the RTP the process is quite simple: all you need to do is carry out numerous game sessions so as to test a title in all its optimal conditions, therefore also activating the bonus games and all the special features.
Ideally, to carry out these tests, the following conditions must be respected:
- It is played repeatedly to take the long term as a reference;
- It is played using the bet at its richest level;
- It is played by activating all the paylines and bonus games;
- The software version must match the one present in the non GamStop casinos.
Clearly this is an ideal scenario that determines the “Theoretical or Maximum RTP”, but users can hardly recreate these conditions, so the most useful data is often reported in terms of Return to Player Min / Max.
Slots With the Highest RTP at Non GamStop Casinos
- Mega Joker– famous as the one with the highest RTP ever, this software published by NetEnt has been the “record title” in terms of Return to Player for several years now, which, apart from this, offers a very classic theme and a structure based on 3 reels and 5 paylines, as well as wild and scatter symbols with which to also aim for a jackpot prize;
- Uncharted Seas– considered one of the most evocative games with a maritime theme, this software created by Thunderkick is structured on 5 reels and 25 paylines and includes both wild and scatter symbols with which to enter a bonus mode much loved by the public, all to make the most of a truly enormous RTP;
- Blood Suckers– with a 5×3 grid and 25 paylines, this horror-themed NetEnt software is another title with a record RTP that has been around for years and has never ceased to attract the attention of users, also thanks to the numerous free spins and an excellent bonus game that paint a rich picture that is only missing a jackpot prize;
- Win the chicken– despite the very high RTP and its much-loved country theme, this software from Skywind owes its fame above all to another detail, that is, a single reel on which the winning symbols appear: a particularly rare feature that makes the game extremely dynamic and engaging, fully justifying the enormous success achieved;
- Jackpot 6000– from NetEnt comes this title based on 5 reels and 10 paylines that stands out first of all for the extreme simplicity with which it allows users to immediately find themselves easily exploiting its operation, in which a jackpot prize stands out capable of paying up to 6,000 credits.
| Slot Name | RTP | Provider |
| Mega Joker | 99% | NetEnt |
| Uncharted Seas | 98.5% | Thunderkick |
| Blood Suckers | 98% | NetEnt |
| Win the chicken | 97% | Skywind |
| Jackpot 6000 | 98.9% | NetEnt |
Providers With the Highest RTP at Non GamStop Casinos
If up to now we have talked about the RTP referred to the various types of slots (or Return to Player) available, now we want to “broaden the picture” by taking into consideration the providers that produce these games.
Of course we are talking about average values that refer to all the titles produced by each provider, but they are still very indicative to get an idea of which brands most commonly offer the highest returns, so that if interested you can visit the relevant reviews and get inspired by the payouts.
The quality of a provider is certainly not measured only in higher RTPs, but it is in any case an indicative aspect, also because the providers mentioned in the table below belong to the ranks of the best brands existing in this sector, manufacturing companies capable of offering quality in its most complete sense.
| Provider | Band (low-medium-high) | Average RTP |
| NetEnt | High | 96.45% |
| Play ‘n go | Medium-High | 96% |
| BetSoft | Average | 95.49% |
| Barcrest | Medium-Low | 94.95% |
When Is an RTP Considered Good at Non GamStop Casinos?
At this point it is worth asking what the criteria are for evaluating whether a slot RTP is good or not, another fundamental step for using this percentage to better understand which games are most suitable for each specific case.
In general, it is possible to say that a Return To Player can be considered as “decent” if it reaches at least 95%, but to be considered as good it must be at least 96%.
Clearly if it exceeds 96% (and even more so if it reaches 99% as with the Mega Joker slot) it should be considered excellent if not even “stellar”, but this does not mean that players should only consider games that reach these levels.
It should be considered that games with a lower min RTP normally offer bonuses with much more acceptable wagering and therefore have a greater chance of being transformed into real money in your deposit account: for this reason the average value of 96% is precisely the most sought-after.
Differences Between Theoretical RTP & the Real RTP
Talking about how the Return to Player of a game is determined, we have already made some evaluations on the difference between the Theoretical RTP and the Real (or min) one: a particularly important topic that deserves a little more space.
As we have seen, the Theoretical RTP establishes the return of a game tested in ideal conditions and for this reason represents the maximum value to which the slot gives access, but these conditions in most cases do not represent those with which users play, for this reason we also speak of Real RTP represented by the percentage to which users can most likely aspire (often defined as RTP min).
The theoretical (or maximum) RTP remains a fundamental point of reference, also because it is certified annually by Curacao respecting the ideal criteria described above, so as to regularly verify that the software always responds to the declared percentages.
