In this review, we check casinos from our list to determine how honest and reliable they are for players. Our goal is to identify which casinos adhere to the declared RTP (Return to Player) rates and which ones deliberately lower them, deceiving players. Casinos that do not maintain fair standards are added to our blacklist. In this review, we will cover 4Kasino, Onedun Casino, Betcoin, Sportaza, Hugewin, Batery.win, Slingo, Del Oro Casino, Fortune Play, and Dream.Bet. We will analyze the RTP and identify which ones are trustworthy and which should be avoided.

4Kasino Check

Starting with 4Kasino, the RTP checks on this platform revealed both positive and negative aspects. Slots from Bgaming, Endorphina, EvoPlay, Kalamba, Mascot, NetEnt, and Pragmatic Play showed stable and high RTP values. However, RTP reductions were found in slots from Microgaming, Play’n GO, and TrueLab.

Onedun Casino Check

Next up is Onedun Casino. Here, providers like 1x2 Gaming and Evoplay stand out with significant RTP reductions, reaching 88% on Keno Pop and 93% on Clash Of Pirates. Reductions were also noted with Red Tiger Gaming. However, providers like BGaming and Thunderkick show high RTPs, which slightly balances the overall picture, but we would recommend avoiding slots with low RTPs.

Betcoin Check

In the case of Betcoin, the check revealed mostly high RTP values, with some exceptions. Slots from 1x2 Gaming, Bgaming, Endorphina, Gamomat, Kalamba, Netent, Platipus, Pragmatic Play, Push Gaming, and Thunderkick demonstrated high and stable RTPs, indicating the casino's fairness. However, RTP reductions were found in some slots from Hacksaw Gaming and Nolimit City, raising concerns. Despite this, overall, Betcoin supports a transparent and fair policy, making the chances of winning real.

Sportaza Check

Moving on to Sportaza, this casino shows a reduction in RTP across many providers, such as Nolimit City, Red Tiger, Push Gaming, and Pragmatic. Notably, Play’n GO Gaming’s RTP drops to 91%, severely affecting the chances of winning. This casino has been added to the blacklist.

Hugewin Check

Next in the review is Hugewin. The situation here is slightly better but still problematic. Significant RTP reductions were recorded with Hacksaw Gaming, Nolimit City, and Pragmatic Play. TrueLab also showed substantial deviations from the norm. Otherwise, most providers, such as Avatar UX and BetSoft, display high and stable RTPs, making Hugewin partially reliable, but caution is advised when selecting slots.

Batery.win Casino Check

Next, let's consider Batery.win Casino. Slots from providers like AvatarUX, Bgaming, Endorphina, Evoplay, and Play'n Go demonstrated fair and stable RTPs. However, significant RTP reductions were found in slots from Hacksaw Gaming, Kalamba, Microgaming, Push Gaming, Quickspin, Thunderkick, and Yggdrasil. This seriously affects players' chances of winning, making Batery.win less reliable.

Slingo Check

The situation here is quite alarming: providers like Hacksaw Gaming, Netent, and Nolimit City show significant RTP reductions, casting doubt on the casino's fairness. Reductions to 92% with Hacksaw Gaming and Nolimit City make playing these slots highly disadvantageous. Slots from BGaming show high RTPs, but this does not save the overall picture. Slingo also goes on our blacklist.

Del Oro Casino Check

Now let’s discuss Del Oro Casino. RTP reductions were found in slots from Evoplay, Nolimit City, and Pragmatic Play. This indicates dishonest actions by the casino, significantly reducing players' chances of winning. Despite good performance from some providers, Del Oro does not provide fair gaming conditions overall.

Fortune Play Check

The Fortune Play check revealed serious RTP issues with providers like Evoplay, Hacksaw Gaming, Nolimit City, and Pragmatic Play. RTP reductions are significant and often reach 94%, which is not encouraging for players. Even Red Tiger Gaming and TrueLab face similar problems. In the end, playing here is risky, and we add Fortune Play to our blacklist.

Dream.Bet Check

Finally, let’s review Dream.Bet. The check showed that slots from Bgaming, Play'n Go, Microgaming, and Yggdrasil demonstrated significant RTP reductions. For example, Play'n Go slots had an RTP of around 87%, significantly lower than the normal values of around 96%. Winning at Dream.Bet is almost impossible, and we are sending it to the blacklist.

Conclusion

After thoroughly checking the RTP at various casinos, we can draw several conclusions. 4Kasino and Betcoin showed high and stable RTPs in most of their slots, with a few exceptions.

However, not everything is rosy, and casinos like Sportaza, Slingo, Fortune Play, and Dream.Bet are added to our blacklist as they showed the most significant deviations from declared RTP values. We recommend players avoid these casinos to avoid risks and avoid losing money due to dishonest practices.

Dear readers, always check RTP and the reputation of casinos before starting to play. Follow our recommendations and be careful when choosing a platform to play on, so your chances of winning are fair and justified.
