OneSlot Casino Review: Bonuses, RTP and Complaints

Slots from AvatarUX at OneSlot Casino pleased with stability. All tested games show an RTP of around 96%, which is in line with the developer's standard metrics. We did not find a single case of underreporting of returns, which suggests that the conditions in this section of the casino are fair.

• 80spop – RTP 96.01%

• Animals Strike – RTP 96%

• Arcanapop – RTP 95.9%

• Gods Gone Wild – RTP 96%

• Imperial Coins – RTP 96%

• Pixel Paws – RTP 96%

BGaming is traditionally famous for its generous slots with RTPs above 96%, and OneSlot Casino is no exception. Even if there is one slot with an RTP below 95%, this is a feature of the game itself, and not a decrease in return. Otherwise, the tested machines showed honest and high coefficients, without any understatement.

• Aloha King Elvis – RTP 94.98%

• Aztec Magic – RTP 96.96%

• Disco Party – RTP 97.01%

• Lucky Ducky – RTP 97.25%

• Lucky Lady's Clover – RTP 97.31%

• Sakura Riches 60 – RTP 97.16%

Slots from Evoplay at OneSlot Casino have shown standard results.

• Battle Rooster – RTP 96.01%

• Big Catch – RTP 94%

• Europe Transit Snowdrift – RTP 96.18%

• Talismans Of Fortune – RTP 93%

• Winter Star Bonus Buy – RTP 96.04%

• Young Wolf Song – RTP 96%

This is where the alarming trend begins: in almost all the tested slots from Hacksaw Gaming, we found a noticeable decrease in RTP. Under normal conditions, these machines should offer a return of around 96%, but in OneSlot Casino, the figures drop to 92% and even 88%. This is a tangible difference that significantly reduces the chances of players winning. Obviously, this provider in this casino has undergone a serious decrease in RTP, which makes its slots extremely unprofitable.

• Duel At Dawn – RTP 92.28% (normal 96.3)

• The Bandit – RTP 88.36% (normal 96.34)

• Le Viking – RTP 88.27% (normal 96.4)

• Rip City – RTP 92.32% (normal 96.22)

• Sixsixsix – RTP 92.17% (normal 96.23)

• Wanted Dead Or A Wild – RTP 94.55% (normal 96.38)

Unlike many other providers, NetEnt at OneSlot Casino was unable to maintain the declared RTP levels. Several popular slots recorded a decrease from 96% to 94% and even lower. This is especially evident in well-known games that traditionally have high returns, but in this casino they have become less profitable. This is another worrying sign for players.

• 101 Candies – RTP 94.07% (normal 96.06)

• Butterfly Staxx – RTP 96.80%

• Dazzle Me – RTP 93.05% (normal 96.90)

• Jumanji – RTP 96.33%

• Ms Robin Hood – RTP 94.12% (normal 96.08)

• Reel Rush – RTP 92.05% (normal 96.96)

In most of the slots from Nolimit City, we have seen honest RTP rates that correspond to the official data. The only exception is one slot in which the RTP is underestimated by 2%. Overall, the provider performs well, and most of the games can be considered safe to play.

• Blood & Shadow 2 – RTP 96.09%

• Outsourced – RTP 96.08%

• Punk Rocker 2 – RTP 96.06%

• Wixx – RTP 96.61%

• Xways Hoarder 2 – RTP 94.06% (normal 96.05)

• Xways Hoarder Xsplit – RTP 96.14%

Another provider that has been found to have a massive decrease in RTP. In all proven Pragmatic Play slots, the return is underestimated from 96% to 94-95%, which is disappointing. It's especially frustrating to see this in hits that are popular with players and are supposed to offer fair odds of winning. There is a clear trend towards a decrease in returns.

• Gates Of Olympus 1000 – RTP 94% (normal 96)

• Gates Of Olympus – RTP 94.50% (normal 96.50)

• Starlight Princess – 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 – RTP 95.51% (normal 96.51)

Quickspin also did not avoid a decrease in RTP at OneSlot Casino.

• Pearl O' Plinko – Mermaid Cove – RTP 94.19% (normal 96.17)

• Pied Piper – RTP 96.32%

• Pineapple Crush – RTP 87.15% (normal 96.13)

• Pirate's Charm – RTP 96.49%

• Primal Spirits – RTP 87.15% (normal 96.16)

• Rapunzel's Tower – RTP 96.25%

Red Tiger at OneSlot Casino turned out to be one of the most problematic providers. In almost all checked slots, a decrease in RTP from 96% to 93-94% was found. This is a significant difference that significantly reduces the probability of winning. This approach of the casino clearly does not play into the hands of players, but rather, on the contrary, makes the game less fair.

• Bounty Raid 2 – RTP 93.7% (normal 95.68)

• Case Closed – RTP 94.1% (normal 96.02)

• Cash Explorer – RTP 93.73% (normal 95.78)

• Dragons’ Lock – RTP 93.72% (normal 95.81)

• London Tube – RTP 93.74% (normal 96)

• Wings Of Ra Megaways – RTP 93.7% (normal 95.8)

Unlike many other providers, Thunderkick at OneSlot Casino has retained the original RTP values. All the slots tested showed honest performance, and one even exceeded 98%, which is an excellent result. You can play here without fear.

• 12 Bolts Of Thunder – RTP 94.21%

• 1429 Uncharted Seas – RTP 98.6%

• Eager Beavers – RTP 94.29%

• Esqueleto Explosivo 3 – RTP 94.22%

• Split Happens – RTP 94.16%

• Ways Of Athena – RTP 94.21%

Yggdrasil also did not fall under the wave of RTP declines. All tested slots showed the standard 96%, and there was not a single case of underreporting. In this section of the casino, the conditions are fair and transparent.

• 3 Gladiators Vs Caesar – RTP 94%

• Boilin’ Pots – RTP 96%

• E Force – RTP 96%

• Enchanted Waters – RTP 96%

• Trickstar Spins – RTP 94%

• Valley Of The Gods – RTP 96.2%

Analyzing the situation, it becomes clear that it will be extremely difficult to win at OneSlot Casino. Too many providers have been affected by the RTP decline, with Hacksaw Gaming, NetEnt, Pragmatic Play, Quickspin, and Red Tiger being hit particularly hard. Massive reductions in RTP to critical values of 88-94% make playing in these slots unpromising. Of course, some providers (Thunderkick, Yggdrasil, AvatarUX) have remained unchanged, but in general, OneSlot Casino clearly does not play in favor of its users. With such a level of understated RTP, it is almost impossible to win here, which means it is better to look for a more honest platform.
