Discussion about article: Games of chance: RTP and variance

Great read! It covers fair play, RTP, and responsible gambling well. Many overlook bonus restrictions and how volatility affects short-term wins. Would love to see more on crypto casinos. Thanks for sharing

Hello, I'm glad you like our guide. That's what it's all about, to give players as much information as possible. Is RTP important to you for slots or other games and do you choose based on that? Do you play the ones that have more or less volatility?😀

We should take a look at the licenses of casinos and the fact that Curacao ones doesn't require to publish RTP in the slots, consider also a big difference in Pragmatic slots where casinos are just setting 94% RTP for Gates of Olympus, Big Bass "x" and other popular slots while honest casinos are applying the standard RTP of 96,5%. Be aware of that guys, its pure scam.

Is it also in the Terms of the license itself that they don't have to show the RTP on the slots? That's probably something I would personally like to see if I played slots somewhere. So how do you know that some casinos have low RTP on pragmatic if you can't see it? Have you asked them?

I will show you here 3 screenshots, 2 from casinos in Belgim and 1 under Curacao license; first of the screenshot you see is casino NapoleonGames.be - the second one is also a casino with Belgian license Starcasino.be and the RTP is correct: 96.5%. On the 3th screenshot you see as well Gates of Olympus but from Europa777.com operated by TriMat Gaming B.V. under the laws of Curaçao.

Hello, I guess this is what Jaro has been talking about. Some providers offer casinos a different set of RTPs so the casino can pick up their choice. Hence, it is always best not to rely on expected RTP, but check out the games just like you did.

94% is terrible RTP, and avoiding the value completely is not very convenient either, if I may voice my opinion.

Considering the game provider allows such picks, it is not about the correct RTP anymore.

​The worst thing one can encounter is the complete concealment of RTP. I came across this even in a Belgian casino. The slot Book of Dead does not display any RTP information in its slot details. I wrote to the casino for clarification. While I am not an expert in the field of licenses and laws that Belgian operators must comply with, it seems to me that this is rather illegal.​

A very useful article!  

Thank you, Casino Guru, for such a detailed and interesting piece. We believe it will be valuable for all players to read.  

We’ve actually been using the article pretty much every time a colleague of ours needs to know more about the RTP who isn’t typically a part of a team that deals with games. Saves up tons of time.

Great article and thoughtful responses here. I think RTP and volatility are great tools for players to better understand what to expect, but at the end of the day, playing should still be about enjoyment. I like that many casinos are now more transparent about this info, helping people make informed choices. A good balance between fun and fairness goes a long way in building trust.

Hello. Excellent article, but there are a few clarifications. Why do you believe volatility cannot be expressed numerically? Why aren't you satisfied with standard deviation as a measure of volatility? For example, Thunderkick provider in their documentation indicates standard deviation as volatility, although the player cannot see this figure in the slot itself.

I believe that using words like 'high' or 'low' is manipulation. Let's also write about RTP that it's high and low, because

The RTP of slots is a bit more complicated. You can hit many various winning combinations and win many different multiples of your bet. Due to this, it's not that simple to describe slot RTP by one number, and game providers only use loose descriptions like "small", "medium", and "high" for their slot machines.

Variance of the game can also be described by the statistical distribution of winnings.

It's important to emphasize that this uses a specific numerical value, which can be used to accurately describe volatility rather than relying on subjective descriptors."

Hi! Great article. So, if you’re on a tight budget and want entertainment, go low variance. If you’re feeling brave and chasing those jackpot fireworks, high variance is your playground...just buckle up, it can be a bumpy ride!

Good info, thanks! Gonna try the roulette tactic at weiss bet👌

Hello,

The casino Europa777 doesn't have an official license and actually offers a lot of what i called fake slots.

I am surprised that sites like casino guru or lcb didn't notice it. I mean when you search for a game it will appear several times and i personally can recognize a fake slot. Also, i have received a free spin feature several times, then suddenly their game will bug and when you go back to the game, the free spin feature is gone and you are just like when you open game. You contact them to say it but they don't even reply. The real slot will save your progress and when you go back, it will just continue where it was.

Casino Guru members, can i open a complaint because i played a fake slot? For example i know that the game Book of ra 6 i played is fake. I compared it with the real one and i am 1000% sure that i played a fake version of it. They have many other slots which are fake.

Hello!

I'm not sure we can investigate such situations because we don't have access to game assets, and because we're not a licensing authority, we can't demand an investigation in collaboration with providers. 

As far as I know, those complaints have not been accepted. I cannot promise you alternative events.

It seems to be a different game version. PP allows this. There are many different versions, even graphically enhanced official versions, of such popular slots. In some cases, the RTP varies, Zeus may wear different outfits, or the name might be altered to reflect the casino brand.

You may, however, use this "update us" button to submit your findings to the Data Team.

Hello Radka,

yes i know that some games have different variant but not those i play. And normally the fixed lines are not paid differently, for example there is no 2 versions of the game Ancient Egypt classic from Pragmatic play, although during free spins feature normally a line formed by the expanding symbol will not pay, but on their slot it pays. Also there are an incredible number of dead spins.

On their game book of dead, there are 4 versions of them when we search for it. One is real because when i try to access it, a message pop up saying that i cannot play it because i am in Switzerland due to regulations and it is true. Although the other ones i can play and i know all of the 3 are fake. One has always the same teasing, having the relic passing by 1 place. Also, in the past they used to have the old versions with the books and not with the relics, which is also a proof it is fake.

On the game immortal romance, during wild desire feature, you will never get more than 2 wild reels and you will never have them on the first 3 reels, only on reels 4 and 5. I have played this game for a decade and it is very suspicious that out of 100 wild desires feature it is always the same. In plus, normally the game will save your progress and each free spin feature, you can unlock Troy, Mickael and Sarah but on their slot if i leave the game and come back, it all starts from beginning and you have to have 14 free spins features again to unlock Sarah.

I will conclude by saying that i had several free spins feature, the game crashes and when i go back on the game, the free spin feature is gone and it is like i opened the game for first time. The real slot will always save your progress and the free spin feature will continue when you go back on the game, but there i had like 5 free spins feature which were gone. I contacted the support, they told me they will contact provider to see problem, it has been a week i have no answer. Another thing to prove that it is fake is that when free spins will come on the game Rage Lion, there will always be like a sort of lag or freeze of the game and you know you will get it.

I am not saying that all of the games are fake but honestly they have a lot of fake ones. You can try to go and search for random games, you will see they will appear up to 5 times. Play your favorite game dear and compare to the real one.

Hello!

Thank you for the very detailed observations. You should share your findings with the game providers, since only they can compare the title with the original files and issue an official statement. In some cases modifications can occur during distribution through third parties, which may explain differences you noticed, but we cannot officially verify that ourselves; we have no access to the source codes. Data Tam may, however, find this information useful.

For unlicensed casinos, the provider remains the only formal contact to resolve this.

Your report will still help other players stay informed, of course.

Hello dear,

the casino accepted to refund my deposit and is doing an investigation about the issue reported. Since i got my money back, i hope everything will be fixed in the future. As i can see those mentioned slots have been removed.

👏👏👏

Hello there, what an amazingly positive outcome. Just to understand this correctly, did you inform the gameprovider or did the casino take action on its own? In any case, the result is very good news, and I thank you for that.
