Erilaiset RTP-pisteet kasinoilla

Hello @ all.

I have a question for those who are more familiar with the technical side of online gambling.

Some time ago I noticed that in some casinos the RTP values for certain games differ.

In my particular case, I was able to observe this fact in some games from Pragmatic Games.

For example, Gates of Olympus, Gates of Hades, and many games from the BIG Bass series have an RTP of 94.7% on some sites. However, the original Pragmatic game gives a slightly higher RTP of 96.5% for these games.

Which you can also see here in the demo versions of the games on Casino-Guru.

Since this of course increases the profit margin for the casino enormously and you "bleed out much faster" I have been asking myself the question the whole time,

how something like this can be technically implemented by a casino...

Until now, I always assumed that when I play at any casino, the casino more or less establishes a direct connection to the game provider's server and essentially acts as an interface...

In this case, what that means to me is that the casino itself has no influence on the payout of the games, and the whole thing is, or should be, fair and safe for us as users...

Now, for this very reason, I have been racking my brains over this topic for some time now and I constantly ask myself,

a.) as in 3 devil names, that whole thing is accomplished.

and

b.) who can then guarantee us that the machines have not been/will not be manipulated even more extensively...

Is this feature offered to the various casinos as an option by the API operator, or do the casinos themselves have their foot on the brakes?

I remember from the time when our family still had our own "analog" slot machine, that you could manually set in the system how often and in what order of magnitude the machine should pay out winnings.

Can the technical principle be compared in some way?

What do you think about it?

From online poker, for example, I know that the servers required to ultimately control these games had the strictest requirements and guidelines to prevent any unwanted access from outside at all costs, and in practical terms, should not even be possible at all.

I think it's similar with the state lottery and similar events, where even the provider itself doesn't have access or could influence the game in any way...

I would be very happy to receive answers to my questions on this topic and am already curious to hear your opinions.

Greetings and lots of big scatters to everyone. xD

Hello @ all.

Ich habe eine Frage an diejenigen die sich etwas umfangreicher mit der technischen Seite des Online Glücksspiels auskennen.

Vor einiger Zeit ist mir aufgefallen, dass sich in einigen Casinos die RTP Werte bei bestimmten Spielen unterscheiden.

Im meinem speziellen Fall konnte ich diese Tatsache bei einigen Spielen vom Pragmatic-Games feststellen.

So haben Beispielsweise u.a. "Gates of Olympus, Gates of Hades, und auch viele Spiele aus der BIG Bass Serie, auf manchen Seiten einen Wert von 94,7% RTP. Das Original von Pragmatic gibt bei diesen Spielen jedoch einen etwas höheren Wert von 96,5% RTP an. 

Was man auch hier in den Demo-Versionen der Spiele auf Casino-Guru sehen kann.

Da sich hierdurch nun natürlich die Gewinnmarge für das Casino enorm vergrößert und man somit "viel schneller ausblutet" stelle ich mir nun schon die Ganze Zeit die Frage,

wie sowas von einem Casino technisch umgesetzt werden kann...

Bisweilen ging ich immer davon aus, dass wenn ich in irgend einem Casino spiele, dieses Casino mehr oder weniger eine direkte Verbindung zu dem Server des Spieleanbieters aufbaut, und quasi nur als Schnittstelle hierbei fungiert...

Was für mich in dem Fall auch soviel bedeutet wie, dass das Casino selbst keinerlei Einfluss auf die jeweiligen Gewinnausschüttung der Spiele nehmen kann und das ganze für uns als User dementsprechend auch fair und eine sichere Angelegenheit ist bzw. sein sollte...

Nun zerbreche ich mir aber genau aus diesem Grund schon seit geraumer Zeit an diesem Thema den Schädel und frage mich ständig, 

a.) wie in 3 Teufelsnamen, dass ganze Bewerkstelligt wird.

und 

b.) wer uns hierbei dann am Ende überhaupt noch garantieren kann, dass die Automaten letztendlich nicht sogar noch viel viel umfangreicher manipuliert wurden/werden...

Wird den verschiedenen Casinos dieses Feature sozusagen optional von Seiten des API Betreibers angeboten oder haben die Casinos hierzu selbst den Fuß auf der Bremse?

Ich weiß noch von damals aus der Zeit als wir in unserem Familienkreis noch einen eigenen "analogen" Geldspielautomaten" besaßen, dass man dort im System manuell festlegen konnte, wie häufig und in welcher Größenordnung der Automat eine Gewinnausschüttungen erzogen soll.

Lässt sich das technische Prinzip hierbei etwas vergleichen?

Was denkt ihr darüber?

Vom Online Poker beispielsweise weiß ich, dass die hierfür notwendigen Server die diese Spiele letztendlich steuern, die allerstrengsten Auflagen und Richtlinien besaßen, um einen ungewollten Zugriff von Außerhalb in jedem Fall zu unterbinden, und praktisch gesehen, auch überhaupt nicht möglich sein sollte.

Ich denke ähnlich läuft es ja auch bei der staatlichen Lotterie und ähnlichen Veranstaltungen ab, bei denen ja ebenfalls nichtmals der Anbieter selbst den Zugriff hat oder in irgendeinerweise Einfluss aufs Spiel nehmen könnte...

Würde mich über Antworten auf meine Fragen zu diesem Thema sehr freuen und bin jetzt schon auf eure Meinungen gespannt.

Grüße und jedemenge fette Scatter an alle. 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.

Hello batistahector490,

I'm very pleased that my post caught your attention and has now led to some rather interesting conversations. The thing with me is that I wouldn't describe myself as an experienced player, and some of my observations are probably selective perceptions. Overall, as far as I know, I find it rather difficult to make statements that speak as evidence for or against these percentages.

In poker, this was always referred to as a necessary sample size.

I have no idea how high it should or would have to be for slot machines to ultimately have truly meaningful values... I think with less than 10,000-100,000 spins, any of these patterns that you can see can be considered a product of randomness, right?

But to be honest, I find this topic quite fascinating.

I have always loved exploring the mathematics behind the simplest strategic games.

I am therefore already looking forward to hearing more about this from your perspective.

Because, if you really look at it closely, I would still consider myself an absolute beginner in this field.

Best regards

Hallo batistahector490,

es freut mich sehr dass mein Beitrag deine Aufmerksamkeit erregt hat und hier nun zu ziemlich spannenden Unterhaltungen führt. Das Ding bei mir ist, dass ich mich selbst nicht als erfahrenden Spieler bezeichnen würde und vermutlich manche meiner Beobachtungen mit Sicherheit auch selektive Wahrnehmungen sind und ich es insgesamt, stand meines Wissens betrachtet, auch eher für Schwierig halte, Aussagen zu treffen, die als Beweise für oder gegen diese Prozentzahlen sprechen.

Beim Pokern sprach man hierbei immer von einer hierfür notwendigen Samplesize.

Keine Ahnung wie hoch die bei Slotmachines sein sollte bzw. müsste um letztendlich wirklich Aussagekräftige Werte zu haben... Ich denke unter 10.000-100.000 Spins lässt sich jedes dieser Muster, die man hierbei erkennen kann, als Produkt der Zufälligkeit betrachten, oder?

Finde dieses Thema aber um ehrlich zu sein auch ziemlich faszinierend.

Schon früher habe ich es geliebt die Mathematik hinter den einfachsten Strategischen Spielen zu erforschen.

Freue mich deshalb auch jetzt schon darüber, mehr hierzu aus eurer Sicht zu erfahren.

Weil, wenn man es wirklich genau nimmt, ich mich selbst noch zu den absoluten Anfängern auf diesem Gebiet zählen würde.

Liebe Grüße

Wow, this post of yours really fills my heart with warmth..

Thank you very much for your kind words and I am glad that the impression I have had in the meantime has been confirmed by other players like you.

To be honest, I have to admit to myself that I was also quite naive and naive in dealing with certain situations... So a not insignificant part of the blame for this lies with me.

But this is exactly where my thoughts begin again.

Example:

• I go to a live casino (not your run-of-the-mill arcade) and sit down at a slot machine and play. Regardless of whether I win or lose, how would the next machine know how my previous session went? And then, after a big win, let me lose dozens of games in a row? The machine itself doesn't have any relevant data for this.
• In online casinos, however, this impression quickly becomes apparent and is sometimes even confirmed directly, as long as you do not deviate from your previous strategy and simply continue playing the same way.

I read somewhere that there's a law in Germany to protect (prevent) players from gambling addiction, which requires casinos to impose a limit on the playing time per device (I think it was a maximum of 5 hours).

And I could swear that I have now experienced this exact result myself several times.

• In the game Jammin Jar2 e.g.

At a certain point, the machine suddenly stops making any cluster connections...

• Here, too, the question automatically arises as to how this player protection law, which doesn't even exist in all other countries, is passed on by the casino to the respective player provider and incorporated into the results.

Wow, dieser Beitrag von dir erfüllt mein Herz wirklich mit Wärme..

Ich danke dir vielmals für deine lieben Worte und bin froh, dass der Eindruck den ich zwischenzeitlich selbst hierbei bekam, von anderen Spielern wie dir, ebenfalls bestätigt wird.

Hierzu muss ich mir selbst allerdings auch ehrlich gesagt offen eingestehen, zum Teil aber auch ziemlich blauäugig und naiv mit den jeweiligen Situationen umgegangen zu sein... Also auch ein nicht unerheblicher Teil der Schuld hierfür bei mir selbst zu finden ist.

Aber genau hier an der Stelle fangen ja dann auch wieder meine Überlegungen an.

Beispiel:

• Ich gehe ich ein Live Casino (also keine 0815 Spielotheken) und setze mich dort an einen Spielautomat und spiele. Egal ob ich hierbei in diesem Fall nun gewinne oder verliere, woher sollte der nächste Automat nun wissen, wie meine Vorherige Session verlaufen ist.. Und mich nach einem großen Sieg nun zig Spiele in Folge verlieren lassen... Hierzu liegen der Machine ansich ja überhaupt keine relevanten Daten vor.
• Beim Online-Casino hingegen drängt sich einem schnell dieser Eindruck auf und wird zum Teil ja sogar auch direkt bestätigt, sofern man von seiner vorherigen Strategie nicht abweicht und einfach genauso weiterspielt.

Habe irgendwann mal gelesen, dass es in Deutschland ein Gesetz zum Schutz (Vorbeugung) des Spielers vor Spielsucht geben soll, das dem Casino auferlegen soll oder gar muss. Die jeweilige Spielzeit pro Gerät auf (ich glaube es waren max. 5h) zu limitieren.

Und ich könnte schören, exakt dieses Ergebnis, selbst nun mehrfach am eigenem Leib erfahren konnte.

• Beim Spiel Jammin Jar2 z.b.

Ab einem gewissen Zeitpunkt, führt die Machine plötzlich einfach keinerlei Cluster Verbindungen mehr aus...

• Auch hier stellt sich mir dann wieder automatisch die Frage, wie dieses Spielerschutzgesetz, welches es ja auch noch nicht einmal in allen anderen Ländern gibt, durch das Casino an den jeweiligen Spieleranbieter weitergegeben und in die Ergebnisse einfließen gelassen wird..

Many players don't really understand how casino games work. However, if they feel like they're losing too often, they're quick to claim the casino is cheating. I think we all understand that's a flippant statement and a first reaction to simple frustration. These days, many believe a casino is good when they win and bad when they lose. They look for any possible coincidence to support this view—for example, "It's obvious because I recently won big." Folks, coincidence isn't proof. It's just the human mind searching for an explanation for frustration to suppress the fact that gambling isn't as fun anymore because of losses. In my opinion, it's more of a sign of a growing problem.

That's exactly what I meant when I wrote, about admitting a large part of this guilt to myself. You should have some self-reflection in this regard... Sure, it's always nicer to blame someone else for your mistakes... I've done that to some extent in my previous answers, too.

But I've always been a big fan of criticizing myself and blaming myself for certain mistakes.

For this reason, I particularly love sports such as golf, darts and table tennis.

Where it all depends largely on your own hand and eye coordination and you play much more against yourself than against your actual opponent.

Viele Spieler verstehen nicht wirklich, wie Casinospiele funktionieren. Wenn sie jedoch das Gefühl haben, zu oft zu verlieren, behaupten sie schnell, das Casino sei Betrug. Ich glaube, wir alle verstehen, dass das leichtfertig gesagt ist und als erste Reaktion auf einfache Frustrationen empfunden wird. Heutzutage glauben viele, ein Casino sei gut, wenn sie gewinnen, und schlecht, wenn sie verlieren. Sie suchen nach jedem möglichen Zufall, um diese Ansicht zu untermauern – zum Beispiel, dass es offensichtlich ist, weil ich kürzlich einen großen Gewinn erzielt habe. Leute, ein Zufall ist kein Beweis. Es ist nur der menschliche Verstand, der nach einer Erklärung für Frustration sucht, um die Tatsache zu verdrängen, dass das Spielen aufgrund von Verlusten nicht mehr so viel Spaß macht. Meiner Meinung nach ist es eher ein Zeichen für ein wachsendes Problem.

Genau das meinte ich gerade auch als ich schrieb, mir selbst einen großteil dieser Schuld einzugestehen. Soviel Selbstreflektion sollte man hierbei ja schon irgendwie haben... Klar, ist es immer schöner, jemand anderen für seine Fehler verantwortlich zu machen... Habe ich zum Teil in meinen vorherigen Antworten auch gemacht.

Aber ich war schon immer großer Freund davon, mich selbst zu kritisieren und für gewisse Fehler verantwortlich zu machen.

Aus diesem Grund liebe ich beispielsweise auch besonders Sportarten wie Golf, Darten oder Tischtennis.

Wo es großteils auf die eigene Hand- und Augenkoordination ankommt und man viel mehr gegen sich selbst als seinem eigentlichen Gegenspielern spielt.

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.🙂
