Rainbet Casino Review: Bonuses, RTP and Complaints

Let's start with the AvatarUX provider. After checking, it became clear that at Rainbet Casino, all slots from this developer are available with honest RTP rates. In games like Cherry Pop, Monkey Pop and others, the values fully correspond to the maximum versions, without any reductions. It can be seen that Rainbet Casino does not interfere with the settings of AvatarUX slots and leaves the chances of winning at the standard level.

• Cherry Pop – RTP 96.11%

• Cherry Pop Deluxe – RTP 95.90%

• Floridaman – RTP 96%

• Hiphoppop – RTP 96%

• Hippo Pop – RTP 96.06%

• Monkey Pop – RTP 96.33%

In slots from BGaming, the situation also inspires confidence. I checked more than thirty games from this provider and did not find a single case with a decrease in RTP. All slots, including the most popular ones such as Bonanza Billion and Wild Card Gang, run at their maximum levels. Rainbet Casino here maintains full transparency.

• Alien Fruits 2 – RTP 97.17%

The Big Time Gaming provider at Rainbet Casino is also fine. In each of the tested slots - be it Bonanza or Extra Chilli - the RTP level fully corresponds to the declared maximum indicators. The casino does not try to reduce the chances of players, and this is really pleasing.

Endorphina at Rainbet Casino is also good. The proven slots of this developer honestly give an RTP of 96% and above. Rainbet Casino does not reduce the odds in Endorphina games, and this is an important point for those who value transparency in the gameplay.

• Crown Coins – RTP 96.06%

• Hell Hot 100 – RTP 96.07%

• Luxurylife – RTP 96.10%

As for Evoplay, it is worth paying attention to. One of the slots – Big Catch – has an RTP of 94%. This is a low value at first glance, but it is important to understand that this is the maximum value for this particular slot. Other Evoplay slots at Rainbet Casino operate at the advertised levels without reductions. In this case, the casino observes fair game conditions.

• Big Catch – RTP 94%

• Rush Riches – RTP 96.11%

• Tree Of Light Fabled Fruits – RTP 96.20%

In Hacksaw Gaming slots at Rainbet Casino, I did not find a decrease in RTP. All the games I've tested are running stably at their maximum settings. The players' chances here are honestly preserved, and the casino does not interfere with the operation of slots from this provider.

• Duel At Dawn – RTP 96.3%

• The Bandit – RTP 96.34%

• Le Pharaoh – RTP 96.18%

• The Viking – RTP 96.32%

Continuing to check, I did not find any RTP drops in Netent games either. From Aloha Cluster Pays to Dead Or Alive 2, all slots come in fair versions with high RTPs. At Rainbet Casino, players can enjoy the slots of this provider with peace of mind without fear of hidden manipulation.

• Aloha Cluster Pays – RTP 96.42%

• Big Money Wheel – RTP 96.07%

• Dead Or Alive 2 – RTP 96.8%

• Jungle Spirit Megaways – RTP 96.20%

• Lock And Pop – RTP 96.09%

The situation with Nolimit City at Rainbet Casino is also credible. I carefully reviewed many slots and saw honest RTP rates everywhere. The casino does not reduce the chances in these games and leaves the standard settings, which indicates the right approach to working with this provider.

• Dead Dead Or Deader – RTP 96.09%

• Duck Hunters – RTP 96.05%

• Fire In The Hole 3 – RTP 96.05%

• Kill Em All – RTP 96.06%

In Pragmatic Play slots, Rainbet Casino shows its best side. All games from this developer run at maximum RTP, including the popular Sugar Rush 1000 and Sweet Bonanza 1000. There are absolutely no signs of a decline here, and this is encouraging.

• Eye Of Spartacus – RTP 96.42%

• Fire Portals – RTP 96.06%

• Gates Of Olympus – RTP 96.50%

• Sugar Rush 1000 – RTP 96.53%

• Sweet Bonanza 1000 – RTP 96.53%

• Witch Heart Megaways – RTP 96.49%

While checking Print Studios slots, I noticed an interesting picture. In most games, the RTP is kept at the proper level, but one of the slots - Tarasque - has an RTP of 94.30%. Despite this, it is important to emphasize that this is the maximum possible for this game. There are no reductions here, Rainbet Casino has left the original settings of the provider.

• Big Stack Lumberjack – RTP 96.18%

• Cash Defense – RTP 96.29%

• Holy Hand Grenade – RTP 96.45%

• Honey Hunters – RTP 96.61%

• Out Of The Ice – RTP 96.55%

• Tarasque – RTP 94.30%

But with Red Tiger, the situation at Rainbet Casino is frankly alarming. Almost all checked slots turned out to have an understated RTP. In almost all games from this provider, the values are reduced compared to the normal settings. For example, where players usually get around 95.7%, here the value is dropped to 93.7%. In Red Tiger slots, this casino sees a massive decrease in RTP, and this seriously reduces the chances of winning. Unlike other providers, dishonesty is clearly visible here.

• Cannonball Cash – RTP 93.76% (normal 95.7)

• Farmtastic – RTP 93.76% (normal 95.75)

• Nft Megaways – RTP 93.71% (normal 95.66)

• Pirates Plenty – RTP 93.71% (normal 95.12)

• Primate King – RTP 93.67% (normal 95.66)

• Serpent King – RTP 93.71% (normal 95.68)

In Relax Gaming slots at Rainbet Casino, everything is fair. Including the most popular Book Of 99 with a 99% return, all games are available with maximum RTP. The check showed that the casino does not reduce the odds in these slots. You can safely play, knowing that the indicators remain on the side of the player.

• Banana Town – RTP 96.12%

• Book Of 99 – RTP 99%

• Hellcatraz – RTP 96.46%

• Money Train 4 – RTP 96.10%

• Net Gains – RTP 96.10%

• Temple Tumble – RTP 96.25%

The Thunderkick provider at Rainbet Casino also passed the test successfully. Although a couple of slots have an RTP below 96%, it's important to understand that these are standard metrics for these games. I didn't find a drop, all the settings are fair, and the casino gives players a real chance of winning Thunderkick slots.

• 1429 Uncharted Seas – RTP 98.6%

• Divine Lotus – RTP 96.14%

• Eager Beavers – RTP 94.29%

• Hot Potato – RTP 96.16%

• King Of The Party – RTP 94.32%

• Midas Golden Touch – RTP 96.1%

After a full check of slots from different providers, I can say honestly and directly: it is quite possible to win at Rainbet Casino. In the vast majority of games – whether it's Pragmatic Play, Netent, Relax Gaming, Hacksaw Gaming, or others – the casino maintains a fair RTP and provides slots in their best versions. However, you should be extremely careful with games from Red Tiger. It is in them that the casino massively reduces the RTP, significantly worsening the chances of winning. If you plan to play at Rainbet Casino, it is better to avoid slots from this provider, as the chances are greatly reduced in them.

While there’s plenty to like on the surface—licensed under Curacao and backed by recognizable game developers—a closer look reveals both shining highlights and troubling blind spots. Let’s take a deep dive into what Rainbet Casino really offers.

Rainbet Casino operates under a Curacao license (No. 365/JAZ via RBGAMING N.V.), which, while common in the industry, doesn’t guarantee the highest level of player protection. Players should be aware that dispute resolution and oversight under this license tend to be limited. This makes it crucial to carefully read the terms and understand your rights before depositing funds.

The game library is one of Rainbet’s stronger points, with titles from major studios like NetEnt, Pragmatic Play, and Play’n GO. Slot fans will find a decent mix of classics and new releases, while table game lovers can enjoy blackjack, roulette, and baccarat. The live casino offers an immersive experience, but the absence of unique in-house games or niche titles means it may lack long-term appeal for seasoned players.

Although Rainbet regularly updates its game list, some categories like progressive jackpots and niche table games feel underdeveloped compared to competitors.

Rainbet's welcome bonus includes a 100% match up to $500 and 100 free spins, which is competitive. However, bonus terms are not clearly displayed up front, and players report confusion around eligibility and wagering requirements. The no-deposit bonus ($20 for new users) is a nice touch, but it’s locked behind several verification steps that aren’t immediately disclosed.

The Rakeback system is marketed as wager-free, which is commendable—but it only benefits high rollers who gamble large sums consistently. Meanwhile, daily promos and reload offers are average and lack transparency.

Rainbet supports a wide range of payment methods, from Visa and MasterCard to cryptocurrencies like BTC, ETH, LTC, and USDT. Deposit times are fast, especially for crypto users, but withdrawal times can be unpredictable.

While e-wallet withdrawals are processed quickly, bank transfers and card payouts may take up to 5 business days. Complaints about pending withdrawals and delayed KYC verification are common in online forums, raising concerns about Rainbet’s internal processing and support efficiency.

Rainbet offers 24/7 support via live chat and email. In theory, this should mean quick assistance—but in practice, wait times are inconsistent. Some users praise the professionalism of the staff, while others complain of generic, copy-paste responses and unhelpful replies.

There is no telephone support, and the FAQ section is minimal, forcing users to contact support for basic questions.
