RTP Check for Casinos in the Ranking: CasinoDays, Drip Casino, Novibet, and Others
Online casinos are becoming increasingly popular, and it’s essential for players to know how fair they are. In this article, we will check the casinos from our list to find out how trustworthy they are. We will investigate the real RTP (return to player) figures and identify casinos that deceive players by reducing these figures. Casinos that deceive players are added to our blacklist.
CasinoDays Check
Let’s start our review with CasinoDays. Providers like Fantasma and NetEnt showed stable RTP figures without reductions. However, Microgaming had significant reductions: Immortal Romance – RTP 92.1% (standard 96.86), Thunderstruck II – RTP 92.05% (standard 96.65). Slots from Nolimit City and Pragmatic Play also have significantly reduced RTPs. Push Gaming’s RTP is variable, while Red Tiger and Stakelogic are even worse. Thus, CasinoDays clearly reduces RTP, which sends it straight to the blacklist.
Drip Casino Check
Moving on to Drip Casino, the situation looks more favorable. Slots from Bgaming, Endorphina, Evoplay, and Play'n GO maintain high RTPs. However, there are reductions with Push Gaming and Nolimit City. Overall, Drip Casino offers fair conditions, but be cautious with provider choices.
Novibet Check
Now let’s look at Novibet. The check showed that there were no RTP reductions, and the casino provides fair conditions for play.
Slotnite Check
Providers like Bgaming, Elk, Microgaming, NetEnt, and Thunderkick demonstrated high and stable RTP values. However, slots from Blueprint, Hacksaw, Nolimit City, Pragmatic Play, Push Gaming, and Play'n GO were found to have reduced RTPs, significantly lowering winning chances. As a result, Slotnite raises doubts about its fairness, and I cannot recommend it for playing.
Rollino Casino Check
An analysis of Rollino Casino revealed numerous issues. Although providers like Bgaming, Elk Studios, Endorphina, Mascot, NetEnt, and Yggdrasil showed stable RTPs, slots from Evoplay, Hacksaw Gaming, Nolimit City, Play'n GO, Pragmatic Play, Push Gaming, and Red Tiger had significant RTP reductions. Particularly alarming is the reduction in Play'n GO slots to 87%. Consequently, Rollino Casino lands in our blacklist, and I do not recommend playing at this casino.
Cobber Casino Check
Now let’s move on to Cobber Casino. Almost all tested providers showed reduced RTPs. For example, Candy Monsta by Bgaming – RTP 87.04% (standard 94.06), Book Of Fastpay by Evoplay – RTP 92% (standard 96). Slots from NetEnt and Yggdrasil were also significantly reduced. Given these figures, winning at Cobber Casino is almost impossible, and this casino is added to the blacklist.
JVSpin Check
The RTP check of this casino revealed that most slots maintain their original values, which is a positive sign for players. Providers like Apollo Games, BGaming, Endorphina, EvoPlay, Fugaso, Mascot, Pragmatic Play, Quickspin, and True Lab demonstrated stable RTPs. The only exception was Red Tiger, where some slots had their RTPs reduced to 92.69%. Therefore, JVSpin can be recommended for playing, except for Red Tiger slots, which are best avoided.
Spinarium Check
Spinarium showed good results in the check. All tested slots from providers such as 1x2 Gaming, Bgaming, Big Time Gaming, Endorphina, Hacksaw, Kalamba, Nolimit City, Pragmatic Play, Push Gaming, Quickspin, TrueLab, Wazdan, and Play'n Go maintained their original RTP values. This indicates the honesty and transparency of the casino, and it can be recommended for playing.
CasinoVibes Check
Next, let's look at CasinoVibes. Providers like Bgaming, Evoplay, Fugaso, Merkur, NetEnt, and Nolimit City maintained high RTP values. However, slots from Hacksaw Gaming, Push Gaming, Play’n GO, and Microgaming were reduced. Especially notable are Beast Below – RTP 94.27% (standard 96.29) and Action Cash™ Lightning Bounty – RTP 94.24% (standard 96.2). CasinoVibes offers good conditions for play, but avoid slots with reduced RTP.
Bet Grouse Check
Lastly, let's review Bet Grouse. Providers like 1x2 Gaming and Blueprint showed stable RTPs, but Hacksaw Gaming, Microgaming, and NetEnt have reduced figures. Particularly unpleasant is the reduction by QuickSpin, for example, Beastwood – RTP 87.15% (standard 96.04). Given the numerous reductions across different providers, Bet Grouse is also not recommended for fair play and is added to the blacklist.
Conclusion
Based on the review of several online casinos, it can be concluded that very few establishments offer fair playing conditions. Most casinos resort to manipulating RTP, significantly reducing players’ chances of winning. In today’s review, several casinos, such as CasinoDays, Rollino Casino, Cobber Casino, and Bet Grouse, failed the check and were added to the blacklist.
We continue to monitor and check online casinos to ensure fair conditions for all players. If you have experience or information about RTP reductions in other casinos, share it with us! Your safety and fair play are our priority.



YellowPikmin Yes, I remember the Avengers slot... I caught such drifts there. I still regret that I did not take a screenshot, now you can't prove it.


AccurateShark28 And I bet on six different WTA matches – I won $180 with $10. But there are few days like this :)



thekidgamer52 PSG are really like a tank now. But finals are always nerves. Too often, the favorites fly from the "outsiders". I would take Inter with a handicap, the odds are good, the risk is justified.



Banditmask FILTH! There are simply no words. Forty pieces, so take and squeeze! Poor dude, I can imagine his condition.



CoreSleyes Dead or Alive 2 is still a legend. I have been playing it since 2019. There is still no feeling that it is outdated.
I’d ban all of them altogether.
Will there be a review of honest ones?
You’d be better off doing something useful instead of playing at these casinos.
As always.
I wonder if any of these casinos will actually respond to such accusations? Or will they stay silent, as always?
