Monster Win Casino came to our attention, and we decided to conduct an independent fairness check - we studied dozens of slots from popular providers to find out if the platform underestimates the RTP in games. Such hidden manipulations directly affect the player's chance of winning and may indicate an unfair policy on the part of the casino. In this article, I will detail which providers and games turned out to be fair, and where serious problems were identified.
Bgaming RTP
Let's start with the Bgaming provider. The situation here is depressing: in almost all slots, a clear fact of a decrease in RTP was recorded. Games that are usually distinguished by good returns are given out an order of magnitude less at Monster Win Casino. About 30 slots were tested - and a decrease was recorded in most of them. This is not just a minor difference, but a noticeable drawdown in percentage, which makes the game process much less profitable for the user. Such an approach only creates distrust in the platform.
-
Alice Wonderluck – RTP 94.03% (normal 97)
-
All Star Fruits – RTP 94.05% (normal 97.04)
-
Disco Party – RTP 94% (normal 97.03)
-
Sakura Riches 60 – RTP 94.05% (normal 96)
-
Treasure Of Anubis – RTP 97.13%
-
Wild Clusters – RTP 96.71%
ELK RTP
But with ELK, the situation looks much more clear, although not for the better. Absolutely all tested slots have the same low RTP - 94%. This is not a decrease from the maximum values, but just initially low settings. That is, Monster Win Casino does not seem to violate anything here, but it is difficult to call such values an honest return - you play with minimal chances of winning.
-
Catemple – RTP 94%
-
Nitropolis Tv – RTP 94%
-
Orbitfall – RTP 94%
-
Oxygen 2 – RTP 94%
-
Tropicool 3 – RTP 94%
-
Tropicool 4 – RTP 94%
Evoplay RTP
Then it got worse. Evoplay slots have recorded a massive decrease in RTP. The check showed that almost all popular games give 92% instead of the required 96%. It seems that honest versions of slots have simply been disabled here and only the most unprofitable options for the player have been left. Half of the tested slots showed a decrease, which directly indicates manipulation with the settings. With this approach to RTP, it is almost impossible to win.
-
Candy Luck – RTP 92.07% (normal 96.02)
-
Chosen By The Gods – RTP 92.15% (normal 96.1)
-
Dragon Balls – RTP 92% (normal 96)
-
Fruit Fantasy 100 – RTP 92% (normal 96)
-
Hellfire Joker – RTP 92.15% (normal 96.08)
-
The Easter Catch – RTP 92.10% (normal 96.1)
Fugaso RTP
Here's an example of how it should be in a good casino: all proven slots from Fugaso work with the maximum available RTP rates. There is not a single decrease, all values are within the normal range.
-
Book Of Tattoo 2 – RTP 96.5%
-
Clash Of Gods – RTP 96.5%
-
Hercules Power Wild – RTP 96.20%
-
Magic Spinners – RTP 96%
-
Titan Power Wild – RTP 96.20%
-
Trinity Diamond Link Running Wins – RTP 96.15%
Gamomat RTP
But with Gamomat everything is extremely sad. Unlike Fugaso, the situation is the opposite: in absolutely all tested slots, the RTP drops to around 92%. This is a systematic approach, without exceptions. Slots that give good return percentages elsewhere have become drastically "impoverished" here. Such a massive reduction is a direct signal that in this section of the platform, the player will simply not be given a chance.
-
Fancy Fruits Flaming Link – RTP 92.11% (normal 96.1)
-
Great Grizzly – RTP 92.14% (normal 96.12)
-
Royal Seven Deluxe – RTP 92.14% (normal 96.1)
-
Sevens And Books – RTP 92.14% (normal 96.09)
-
The Book Beyond – RTP 94.13% (normal 96.15)
-
Vegas Joker – RTP 92.14% (normal 96)
Hacksaw RTP
This provider also has a lot of questions about the situation. Most of the tested slots have a reduced RTP. In some games, the difference with the norm reaches more than 2%, which turns into significant losses with a long game.
-
Clover Club – RTP 94.25% (normal 96.23)
-
Dorks Of The Deep – RTP 92.21% (normal 96.21)
-
Infernus – RTP 94.23% (normal 96.2)
-
The Bandit – RTP 92.17% (normal 96.34)
-
Life And Death – RTP 92.33% (normal 96.3)
-
Wanted Dead Or A Wild – RTP 94.55% (normal 96.38)
Mascot RTP
Slots from Mascot have also suffered from the greed of the platform. In half of the games, deviations from the standard RTP values were recorded.
-
Cancan Saloon – RTP 95.27% (normal 96.7)
-
Lions Pride – RTP 94.16% (normal 95.9)
-
Northern Heat – RTP 94.84% (normal 95.95)
-
Rekill – RTP 92.2% (normal 95.9)
-
The Rite – RTP 94.29% (normal 96)
-
Wild Spirit – RTP 94.16% (normal 97)
Netent RTP
Against the background of the previous ones, Netent looks almost like a model of honesty. All verified slots work at normal RTP levels – without underestimating or hiding tricks. Even those games where the value is just below 96% are the highest possible settings, so no complaints. This proves once again: it is possible, if there is a desire.
-
Flowers Christmas – RTP 96.32%
-
Go Bananas – RTP 96.91%
-
Jimi Hendrix Online Slot – RTP 96.91%
-
Magic Maid Cafe – RTP 95.97%
-
Space Wars Megaways Xxxtreme – RTP 96.14%
-
Twister – RTP 96.04%
Nolimit City RTP
But with Nolimit City, the situation is quite the opposite. Without exception, all tested slots at Monster Win Casino had a clear decrease in RTP. Each game is below the norm, on average by 4 percent. This is not even a reduction, but just an outright robbery. Moreover, even the top slots, which usually give good winnings, are underestimated. Players here cannot count on even an average return.
-
Duck Hunters – RTP 92.04% (normal 96.03)
-
Home Of The Brave – RTP 92.04% (normal 96.01)
-
Mental – RTP 92.02% (normal 96.08)
-
Munchies – RTP 92.05% (normal 96.02)
-
Stockholm Syndrome – RTP 92.06% (normal 96)
-
Xways Hoarder – RTP 92.04% (normal 96.04)
Pragmatic Play RTP
Pragmatic Play has an almost similar picture. All checked slots turned out to be underestimated.
-
Bandit Megaways – RTP 94.56% (normal 96.5)
-
Book Of Monsters – RTP 94.50% (normal 96.51)
-
Gates Of Olympus – RTP 94.50% (normal 96.50)
-
Sugar Rush – RTP 94.50% (normal 96.52)
-
Sweet Bonanza – RTP 95.5% (normal 96.51)
-
The Dog House Royal Hunt – RTP 94.52% (normal 96.53)
Red Tiger RTP
Red Tiger is a mixed picture. There are honest slots with normal returns, and there are those where underestimation is recorded. About half of the games tested turned out to be "cut", which raises suspicion: either the casino is testing where you can save money, or simply did not bother to set up the slots properly. A player can easily run into both an honest slot and a deception here.
-
Diamonds Up – RTP 95.69%
-
Los Muertos Locos – RTP 93.04% (normal 95.69)
-
Moon Spell – RTP 92.79% (normal 95.77)
-
Serpent King – RTP 95.7%
-
Tiki Fruits – RTP 96.05%
-
Trillionaire Megaways – RTP 95.68%
Thunderkick RTP
And finally, Thunderkick. Here the situation is more positive. Almost all slots run within the normal RTP. Only one game recorded a decrease, and that was not the most critical. In general, if you play at this casino, Thunderkick is perhaps one of the few safe options. It's great to see that at least somewhere Monster Win Casino resisted the temptation to cut everything.
-
1429 Uncharted Seas – RTP 98.6%
-
Explosive Skeleton 2 Reborn – RTP 94.11%
-
Gods Of Rock Reborn – RTP 94.09% (normal 96.05)
-
The Wildos 2 – RTP 94.19%
-
Ways Of Athena – RTP 94.21%
-
Zoom – RTP 96.2%
