Different RTP Scores in Casinos

Γεια σε όλους.

Έχω μια ερώτηση για όσους είναι πιο εξοικειωμένοι με την τεχνική πλευρά των τυχερών παιχνιδιών στο διαδίκτυο.

Πριν από λίγο καιρό παρατήρησα ότι σε ορισμένα καζίνο οι τιμές RTP για ορισμένα παιχνίδια διαφέρουν.

Στη δική μου περίπτωση, μπόρεσα να παρατηρήσω αυτό το γεγονός σε ορισμένα παιχνίδια της Pragmatic Games.

Για παράδειγμα, τα Gates of Olympus, Gates of Hades και πολλά παιχνίδια της σειράς BIG Bass έχουν RTP 94,7% σε ορισμένους ιστότοπους. Ωστόσο, το αρχικό παιχνίδι Pragmatic δίνει ελαφρώς υψηλότερο RTP 96,5% για αυτά τα παιχνίδια.

Το οποίο μπορείτε επίσης να δείτε εδώ στις δοκιμαστικές εκδόσεις των παιχνιδιών στο Casino-Guru.

Δεδομένου ότι αυτό φυσικά αυξάνει τρομερά το περιθώριο κέρδους για το καζίνο και «εξαφανίζεσαι πολύ πιο γρήγορα», αναρωτιέμαι συνέχεια:

πώς κάτι τέτοιο μπορεί τεχνικά να εφαρμοστεί από ένα καζίνο...

Μέχρι τώρα, πάντα υπέθετα ότι όταν παίζω σε οποιοδήποτε καζίνο, το καζίνο λίγο πολύ δημιουργεί μια άμεση σύνδεση με τον διακομιστή του παρόχου παιχνιδιών και ουσιαστικά λειτουργεί ως διεπαφή...

Σε αυτήν την περίπτωση, αυτό σημαίνει για μένα ότι το ίδιο το καζίνο δεν έχει καμία επιρροή στην πληρωμή των παιχνιδιών και ότι όλο αυτό είναι, ή θα έπρεπε να είναι, δίκαιο και ασφαλές για εμάς ως χρήστες...

Τώρα, για αυτόν ακριβώς τον λόγο, βασανίζω το μυαλό μου για αυτό το θέμα εδώ και αρκετό καιρό και αναρωτιέμαι συνεχώς,

α.) όπως και στα 3 ονόματα διαβόλων, όλο αυτό έχει επιτελεστεί.

και

β.) ποιος μπορεί στη συνέχεια να μας εγγυηθεί ότι οι μηχανές δεν έχουν/δεν θα χειραγωγηθούν ακόμη πιο εκτεταμένα...

Προσφέρεται αυτή η δυνατότητα στα διάφορα καζίνο ως επιλογή από τον πάροχο API ή μήπως τα ίδια τα καζίνο έχουν το πόδι τους στο φρένο;

Θυμάμαι από την εποχή που η οικογένειά μας είχε ακόμα το δικό μας «αναλογικό» κουλοχέρη, ότι μπορούσες να ρυθμίσεις χειροκίνητα στο σύστημα πόσο συχνά και με ποια τάξη μεγέθους θα έπρεπε το μηχάνημα να πληρώνει τα κέρδη.

Μπορεί η τεχνική αρχή να συγκριθεί με κάποιο τρόπο;

Τι γνώμη έχεις για αυτό;

Από το online πόκερ, για παράδειγμα, γνωρίζω ότι οι διακομιστές που απαιτούνταν για τον τελικό έλεγχο αυτών των παιχνιδιών είχαν τις αυστηρότερες απαιτήσεις και οδηγίες για να αποτρέψουν οποιαδήποτε ανεπιθύμητη εξωτερική πρόσβαση με κάθε κόστος, και στην πράξη, δεν θα έπρεπε καν να είναι δυνατή.

Νομίζω ότι είναι παρόμοιο με την κρατική λοταρία και παρόμοιες εκδηλώσεις, όπου ακόμη και ο ίδιος ο πάροχος δεν έχει πρόσβαση ή δεν θα μπορούσε να επηρεάσει το παιχνίδι με οποιονδήποτε τρόπο...

Θα χαρώ πολύ να λάβω απαντήσεις στις ερωτήσεις μου σχετικά με αυτό το θέμα και είμαι ήδη περίεργος να ακούσω τις απόψεις σας.

Χαιρετισμούς και πολλά μεγάλα scatter σε όλους. xD

Thanks a lot for your thoughtful post! it's really great to see a player not only noticing the RTP difference but also thinking critically about how it works behind the scenes. You're absolutely right: many modern game providers, including Pragmatic Play, offer multiple RTP versions of the same game (e.g., 96.5%, 95%, 94.7%, etc.), and the casino chooses which one to activate during integration. Sadly, the lower versions are quite common.

From the technical side, especially in the case of licensed casinos, the casino doesn't run the games themselves. Instead, they act more like a marketplace – they integrate the games via API, and the actual game logic (including the RNG and payout distribution) runs on the provider's servers or on a platform controlled by the provider. This means the casino itself doesn’t influence the outcome – they simply stream the game to the player.

That’s also why, if there’s a technical issue with a game, the casino usually has to get in touch with the provider. They often don’t even have access to the raw game data.

Of course, as you mentioned, there are shady unlicensed casinos out there that might use fake or modified games (often with strange visuals or other red flags). But that’s a different story, and these games don’t come from real providers at all.

One thing to note: the analogy with old-school analog slot machines is understandable, but online games don’t work that way. The RTP setting defines the long-term average return, but it doesn't control how often or when the wins happen. There's no manual "win scheduling" like in old hardware.

Your comparison with online poker is interesting too. That’s a different system entirely, with real-time dealing and strict anti-cheating protections. Slot games are much more closed systems, and assuming they come from a reputable provider and are played at a licensed casino, they’re usually safe.

Bottom line: yes, the RTP can vary, and sadly casinos aren't always transparent about it. But spotting that and thinking critically about how games are run is a huge step in the right direction. Always a good idea to check demo versions (like on Casino Guru) to compare with the live version. If something feels off, it might be worth digging deeper.

And hey, wishing you big wins—or at least lots of satisfying scatter teases 😄

Hello Radka,

this is the Art of Conversation that i wish about my questions.

it seems that you are deeper in the knowledge involved and your answers helps me really l aot to understand the secrets behind Online Casino Gamlings (even if I may ignore this during the game and fall into an automatic gamble mode, which may be anything but strategically clever)

You, as someone who obviously knows their stuff. Do you happen to have any good casino recommendations for me? I was able to make a huge profit at Chipstars over the weekend alone

- But they've been holding me back with payouts for over a week,

so I've now resigned myself to leaving this site in the near future... Despite my prospect of the many bonuses still waiting to be earned and redeemed by me...

To be honest, these bonuses were partly my motivation to make deposits on the site in the first place and to get more involved with the casino gambling industry. But now I'm pretty sure that they only see me as a high-paying customer and are strategically using their payout policies against me (basically the classic online casino gambler with dreams).

I don't want to accuse the site of fraud, but certainly of questionable behavior in terms of moral aspects. They know that I'm mentally vulnerable to high risks, yet they deny me the safety net I desperately need by choosing my specific withdrawals. In the last two days alone, I was able to increase my winnings from an original €1,400 to just under €5,000.

Afterward, I was willing to take increased risks, lost most of them, and then yesterday, fortunately, I was able to make my biggest online casino win in a single session to date. (Gates of Hades, 3000x at a €1.40 stake)

For a short time, my bankroll was over €9,000. €2,800 of that is frozen in a current withdrawal process, and I'm using the remaining €6,000 to continue playing, even though I would have preferred to cancel the withdrawal amount again and increase it to €7,000-8,000... I'm now back at €3,100.

So, in less than two days, I've lost more than €3000, and since then, to be honest,

I've just been in the mood to cry...

I'm sure I'm in danger of falling into a typical addiction pattern at this point.

And this is primarily due to the fact that Chipstars strategically drags out its customers' withdrawals to such an extent that they cancel their withdrawal requests themselves during this long period of time in order to stay in the game after the loss...

If I had the option right now to freely choose between a full withdrawal or the waiting process for my current request, I would cancel it immediately and withdraw everything I currently

have on this casino site in one go, then I would choose that option... To put it briefly.

They are not scammers; I was the one stupid enough to fall for this scam. Nevertheless, from a moral point of view, it is more than reprehensible to exploit a player's mental weaknesses for profit-oriented reasons, selfishly out of pure greed, and in doing so, knowingly risk the health of their customers.... So please forgive me for my abusive manner.

Hello again,

Thank you so much for your incredibly honest post!

Please don’t feel the need to apologize. Not here, and not for expressing real emotions around a situation that clearly matters to you. I think many of us can relate to what it feels like when the emotional side takes over, especially in a context like online gambling, where things can shift so quickly between excitement and despair.

What you described isn’t just about one casino. Sadly, these tactics, like delayed withdrawals, tempting bonuses, and nudging players into reversing payouts, are all too common across the industry, especially when the casino is not held to strict standards. It’s not always illegal, but yes, it is morally questionable. And it’s brave of you to call it out like this.

You’re absolutely right to want something better. Everyone deserves a gaming environment where safety nets exist, not where they’re quietly removed just when they’re most needed.

If you're looking for alternatives, I can’t provide personal recommendations, but I suggest using tools like Casino Guru reviews (or any other trustworthy site focused on casino reviews). The more you browse, the better, I'd say. User reviews as well as the casino reviews allow you to filter for fair withdrawal terms, verified licenses, and player-friendly policies. Please include a complaint section to identify the most frequently reported player issues. It won't guarantee a perfect experience, but it helps reduce the risk of getting caught in exactly this kind of trap.

And most importantly, the fact that you're recognizing the pattern, even while it's still playing out, shows real strength. Addiction isn’t about lacking willpower. It’s about the system being designed to exploit the exact things that make us human.

If you ever feel like talking more about it or even want to hear about tools that could help you regain a sense of control, I’m here. No judgment, just open conversation. 🙌

Thanks again for trusting me with this.

Thank you so much for this information, I did not know.

Would you say that even a lower RTP is still better than the so called "original" games used by the crypto casinos?

Let us say Pragmatic, at least we know Pragmatic has every single game approved by a government department somewhere, whereas the classic games are not approved by anyone, the casinos use that ridiculous "provably fair" moniker, which is so insane, Pragmatic uses mathematicians to make their games and then somehow Stake manages to make people with no expertise to believe their unregulated games are "fair".

If Pragmatic can set variable RTPs, i dread to imagine what Stake is doing with their games.

Hello, glad you engaged. I think I know where this concern is coming from.

Just a thing I would like to clarify: The crypto games I mentioned referred to those "decentralized" "provably self-fair algorithms" or anything else you can come up with offered in purely crypto "casinos" invoking the feeling of completely anonymous and unlicensed, therefore insanely cool sites. In most cases, these games are more or less scams, but it is not just the games that may be designed to let you win easily. There are other schemes. I just find it very bold since we all know how the RNG works in normally crafted and licensed slots.

Well, back to the standard games: That's actually a really good question, and one I’ve been thinking about too! When a casino creates and manages its own games, I believe there is a degree of uncertainty regarding "oversight." Officially, it's the licensing authority’s job to make sure everything’s fair, including the RNG. But realistically, many of these authorities don’t have the technical capacity to truly verify how the RNG is implemented, especially when it’s all done in-house by the operator.

So, what I guess usually happens is that everything ends up depending on certificates. But even those may only prove that the RNG engine can work fairly under lab conditions, not that the actual games on the live site always use it in the same way. And when the casino acts as both operator and game provider, there’s no external control in practice, unless they voluntarily submit the games to a reputable independent auditor, which isn’t always the case, I guess.

Well, I don’t think it’s something we can prove, but I wouldn’t personally treat "we have an RNG certificate" as a strong guarantee of fairness when it comes to proprietary games operated directly by the casino.

So, who oversees this at such a casino with an Anjouan license, for example? I do not dare to answer...

Call me a skeptic...

Hi, I saw your post and it caught my attention when you mentioned Pragmatic games, because I’ve been documenting something very similar for a while now.

I’ve also noticed that in certain casinos, the RTP displayed (when they even show it) is lower than the one shown in the demo versions or on Pragmatic’s official site. And the worst part is that players are rarely informed they’re playing a downgraded version , even though that directly impacts their chances.

I’ve been looking into this deeply because I’ve experienced very suspicious sessions, especially on high-volatility slots like Big Bass or Fat Santa (from another provider). In some cases, I’ve even received replies from the provider and gambling authorities , but none of them has taken the time to actually analyze the real evidence I submitted, like videos or specific patterns. They just give generic statements about fairness or "technical compliance."

If you’re interested in continuing to exchange info about this, I’ll definitely be following. I believe many players are noticing things, but very few speak out in detail like you did here.

You’re absolutely right to be skeptical of "provably fair" ,it’s often used as a buzzword in unregulated environments to make players feel safe, when in reality there’s no meaningful oversight. That said, I think both cases (variable RTPs in regulated slots and homemade crypto games) deserve concern.

Even Pragmatic, despite being regulated, has proven how little protection a "government-approved" game can offer in practice. I personally submitted detailed evidence (including videos) showing algorithmic patterns and unnatural sequences in one of their roulette games. And their response? A vague email saying "all our roulettes work this way," without any technical breakdown or investigation. Regulators like the MGA and even the Swiss ESBK didn’t address the actual gameplay anomalies either , just bureaucracy and deflection.

So yes, I’d say variable RTPs are just the beginning. If even games that are "approved" by labs and authorities can act questionably, and no one investigates them seriously, imagine what goes on with completely unregulated ones. The entire ecosystem needs more transparency, whether it’s Pragmatic, Stake, or any other provider.

Well, you didn’t ask me, but I’ll answer anyway.

You asked Radka for a good casino to play at, let me tell you, there’s no such thing as a "good" casino. But if you’re going to pick one, go for one that has a UKGC license. Every other license protects operators or providers , not players.

I saw you mentioned that after a big win, you started losing and ended up with half your balance gone. That’s actually very common. Casinos often mark you as a "recent winner," and from that moment on, you’re not profitable for them , so they push you into a loss cycle, trying to drain more than you originally won.

I know you don’t know me and maybe you won’t believe what I’m saying, but I invite you to check out my thread about Pragmatic Play. If that’s how they run their roulette games, just imagine what goes on with their slots and everything else.

Thanks and take care.👌🏻

I think it is fair to stay objective. This entire conversation revolves around impartiality and openness. Hence, Saying all casinos are not trustworthy, at least to me, sounds pretty much the same like when someone says that all casinos are the same,... They are obviously not. 🙂

Hence I have to be quite hesitant about this.

"I saw you mentioned that after a big win, you started losing and ended up with half your balance gone. That’s actually very common. Casinos often mark you as a "recent winner," and from that moment on, you’re not profitable for them , so they push you into a loss cycle, trying to drain more than you originally won."

I understand that this feeling is very common. That's for sure .🙁

It is always many players who do not actually understand how casino games work; still, if they feel like they are losing too often, they are very eager to proclaim that the casino is a scam. I believe we all understand this is quite an easy thing to say as the first response associated with simple frustrations. These days many people feel that a casino is good when they are winning and becomes bad when they start losing, finding any coincidence they can to support this view—like, e.g., it is obvious because I hit a big win recently. Guys, a coincidence is not proof. It is just a human mind looking for an explanation for frustration to avoid the fact that the gambling is not that pleasing anymore because of loss. It is instead a sign of a rising issue, if you ask me.

Thank you both.

Γεια σου batistahector490,

Χαίρομαι πολύ που η ανάρτησή μου τράβηξε την προσοχή σας και οδήγησε τώρα σε μερικές αρκετά ενδιαφέρουσες συζητήσεις. Το θέμα με εμένα είναι ότι δεν θα περιέγραφα τον εαυτό μου ως έμπειρο παίκτη και ορισμένες από τις παρατηρήσεις μου είναι πιθανώς επιλεκτικές αντιλήψεις. Συνολικά, από όσο γνωρίζω, δυσκολεύομαι να κάνω δηλώσεις που να αποδεικνύουν υπέρ ή κατά αυτών των ποσοστών.

Στο πόκερ, αυτό αναφερόταν πάντα ως απαραίτητο μέγεθος δείγματος.

Δεν έχω ιδέα πόσο υψηλό θα έπρεπε να είναι το κέρδος για να έχουν τελικά πραγματικά ουσιαστικές αξίες οι κουλοχέρηδες... Νομίζω ότι με λιγότερες από 10.000-100.000 περιστροφές, οποιοδήποτε από αυτά τα μοτίβα που μπορείτε να δείτε μπορεί να θεωρηθεί προϊόν τυχαιότητας, σωστά;

Αλλά για να είμαι ειλικρινής, βρίσκω αυτό το θέμα αρκετά ενδιαφέρον.

Πάντα μου άρεσε να εξερευνώ τα μαθηματικά πίσω από τα απλούστερα στρατηγικά παιχνίδια.

Επομένως, ανυπομονώ ήδη να ακούσω περισσότερα σχετικά με αυτό από την πλευρά σας.

Διότι, αν το δεις προσεκτικά, θα θεωρούσα τον εαυτό μου εντελώς αρχάριο σε αυτόν τον τομέα.

Με εκτίμηση

Ουάου, αυτή η ανάρτησή σου πραγματικά γεμίζει την καρδιά μου με ζεστασιά...

Σας ευχαριστώ πολύ για τα καλά σας λόγια και χαίρομαι που η εντύπωση που είχα στο μεταξύ επιβεβαιώθηκε και από άλλους παίκτες σαν εσάς.

Για να είμαι ειλικρινής, πρέπει να παραδεχτώ στον εαυτό μου ότι ήμουν κι εγώ αρκετά αφελής και αφελής στην αντιμετώπιση ορισμένων καταστάσεων... Οπότε ένα όχι ασήμαντο μέρος της ευθύνης για αυτό βαρύνει εμένα.

Αλλά ακριβώς εδώ αρχίζουν ξανά οι σκέψεις μου.

Παράδειγμα:

• Πηγαίνω σε ένα ζωντανό καζίνο (όχι σε ένα συνηθισμένο ηλεκτρονικό κατάστημα) και κάθομαι σε έναν κουλοχέρη και παίζω. Ανεξάρτητα από το αν κερδίσω ή χάσω, πώς θα μάθει το επόμενο μηχάνημα πώς πήγε η προηγούμενη συνεδρία μου; Και μετά, μετά από μια μεγάλη νίκη, με αφήνει να χάσω δεκάδες παιχνίδια στη σειρά; Το ίδιο το μηχάνημα δεν έχει σχετικά δεδομένα για αυτό.
• Στα online καζίνο, ωστόσο, αυτή η εντύπωση γίνεται γρήγορα εμφανής και μερικές φορές επιβεβαιώνεται ακόμη και άμεσα, αρκεί να μην παρεκκλίνετε από την προηγούμενη στρατηγική σας και απλώς να συνεχίσετε να παίζετε με τον ίδιο τρόπο.

Διάβασα κάπου ότι υπάρχει ένας νόμος στη Γερμανία για την προστασία (αποτροπή) των παικτών από τον εθισμό στον τζόγο, ο οποίος απαιτεί από τα καζίνο να επιβάλλουν ένα όριο στον χρόνο παιχνιδιού ανά συσκευή (νομίζω ότι ήταν το πολύ 5 ώρες).

Και θα μπορούσα να ορκιστώ ότι έχω βιώσει αυτό ακριβώς το αποτέλεσμα αρκετές φορές.

• Στο παιχνίδι Jammin Jar2 π.χ.

Σε κάποιο σημείο, το μηχάνημα σταματά ξαφνικά να κάνει συνδέσεις συμπλέγματος...

• Και εδώ, προκύπτει αυτόματα το ερώτημα πώς αυτός ο νόμος περί προστασίας των παικτών, ο οποίος δεν υπάρχει καν σε όλες τις άλλες χώρες, μεταβιβάζεται από το καζίνο στον αντίστοιχο πάροχο παικτών και ενσωματώνεται στα αποτελέσματα.

Πολλοί παίκτες δεν καταλαβαίνουν πραγματικά πώς λειτουργούν τα παιχνίδια καζίνο. Ωστόσο, αν νιώθουν ότι χάνουν πολύ συχνά, σπεύδουν να ισχυριστούν ότι το καζίνο κάνει απάτη. Νομίζω ότι όλοι καταλαβαίνουμε ότι αυτή είναι μια επιπόλαιη δήλωση και μια πρώτη αντίδραση σε απλή απογοήτευση. Στις μέρες μας, πολλοί πιστεύουν ότι ένα καζίνο είναι καλό όταν κερδίζει και κακό όταν χάνει. Ψάχνουν για οποιαδήποτε πιθανή σύμπτωση για να υποστηρίξουν αυτήν την άποψη - για παράδειγμα, "Είναι προφανές γιατί πρόσφατα κέρδισα πολλά". Παιδιά, η σύμπτωση δεν είναι απόδειξη. Είναι απλώς το ανθρώπινο μυαλό που αναζητά μια εξήγηση για την απογοήτευση για να καταστείλει το γεγονός ότι ο τζόγος δεν είναι πλέον τόσο διασκεδαστικός λόγω των απωλειών. Κατά τη γνώμη μου, είναι περισσότερο ένα σημάδι ενός αυξανόμενου προβλήματος.

Αυτό ακριβώς εννοούσα όταν έγραψα, για την παραδοχή ενός μεγάλου μέρους αυτής της ενοχής στον εαυτό μου. Θα πρέπει να κάνεις κάποια αυτοκριτική ως προς αυτό... Σίγουρα, είναι πάντα καλύτερο να κατηγορείς κάποιον άλλον για τα λάθη σου... Το έχω κάνει σε κάποιο βαθμό και στις προηγούμενες απαντήσεις μου.

Αλλά πάντα ήμουν μεγάλος οπαδός της αυτοκριτικής και της επίρριψης ευθυνών για ορισμένα λάθη.

Για αυτόν τον λόγο, αγαπώ ιδιαίτερα αθλήματα όπως το γκολφ, τα βελάκια και το πινγκ πονγκ.

Όπου όλα εξαρτώνται σε μεγάλο βαθμό από τον συντονισμό των χεριών και των ματιών σας και παίζετε πολύ περισσότερο εναντίον του εαυτού σας παρά εναντίον του πραγματικού σας αντιπάλου.

Wow, this is genuinely refreshing to read. 🙌

Huge respect for this level of self-reflection! It's something we unfortunately don’t see often among players. If more people realized that constantly blaming the casino or shouting about how "unfair" everything is usually only deepens the frustration... we'd all be better off. I personally feel this way.

At the end of the day, the only things we can really control are ourselves, our decisions, our mindset, and our expectations.

Thanks for the reminder that gambling, much like golf, often shows us that when things go wrong, the issue might not be with the course but with our own swing...

Much appreciated!

Casinos can adjust RTP values slightly through agreements with game providers, increasing their house edge. This is often done via the casino's API connection to the game, but reputable casinos stick to regulatory guidelines to ensure fairness. For security, games are certified to prevent tampering.

If you're after a platform with good RTP and fair play, check out Weiss.bet!

Yes, it is possible with some providers as you say and casinos can choose the RTP, but they cannot change it arbitrarily as and when they want. This is something that players often confuse. 

The last sentence sounds more like an advertisement for the casino, but that could just be my impression. 

Do you play at Weiss Casino?

II’ve also noticed some big differences in RTP across casinos, especially with Pragmatic Play slots like Gates of Olympus or the Big Bass series. Some sites run them at 96.5%, others at 94.7% or even lower. Kinda feels misleading if you're not paying attention. I thought the games were streamed directly from the provider’s server too - turns out some casinos can choose which RTP version to offer? Anyone here know how this works technically and whether it’s legal everywhere?

Yes, I think it is Pragmatic that gives casinos the possibility to choose some RTP. Either lower or higher. I don't want to mislead, but I think I've dealt with some players in the past, I'm just not sure if it was this provider, although it probably was. 

Anyway, when the provider resp. casino wants slots from a given game provider and there is a possibility to choose RTP, the casino will choose. It works normally and everything is legit. The important thing is if they choose a lower RTP will it discourage the players and I think many of them will and I don't have any statistics on how many casinos choose lower and higher RTP but I think with Pragmatic slots it's more about keeping the higher RTP. It may be that in some cases and therefore casinos it is lower but it is not something that would be "illegal".

Of course, if there was a country where gambling is strictly regulated and for example they had a stipulation that slots must have a certain RTP, then if they offered a lower value it would probably be a problem. 

That's what I know.🙂
