Winningz Casino Review: Bonuses, RTP and Complaints

1x2 Gaming in the casino showed itself quite decently: most slots showed stable RTP rates of about 95%, which is quite in line with the norm. Only one of the tested machines noticed a decrease in RTP, which still leaves the overall impression rather positive.

• 3 Crazy Tikis – RTP 95.13%

• 3 Dragon Pots – RTP 95.3%

• 3 Lucky Minecarts Hold And Win – RTP 93.1% (normal 95.6)

• 420 Blaze It – RTP 95%

• Arriba Heat Megaways – RTP 95.06%

• Smoking Hot Fortunes – RTP 95.2%

But AvatarUX was an unpleasant surprise: almost all the tested machines had a noticeable decrease in RTP compared to the original indicators. The drop reached 2% in some games.

• 80spop – RTP 94.01% (normal 96)

• Animals Strike – RTP 93.98% (normal 96.1)

• Arcanapop – RTP 93.96% (normal 96)

• Beastly Burglars – RTP 94% (normal 96.04)

• Big Catch Craze – RTP 94% (normal 96)

• Bountypop – RTP 96.2%

BGaming was also among those providers where a decrease in RTP was found in almost all slots. The drop in indicators is systemic: almost every slot showed a return rate below the declared normal values.

• Alice Wonderluck – RTP 94.03% (normal 96.2)

• Alien Fruits 2 – RTP 94.14% (normal 96.3)

• Alien Fruits – RTP 94.04% (normal 95.97)

• Aloha King Elvis – RTP 94.98% (normal 94.9)

• Aztec Clusters – RTP 94% (normal 96)

• Beast Band – RTP 94.33% (normal 96.83)

Slots from Evoplay, on the contrary, pleasantly surprised. In most games, the RTP was consistently kept at the level of about 96%, which corresponds to the norm. Only one machine showed a decrease, but in general, Evoplay in the casino looks quite reliable.

• Ace Round – RTP 96.01%

• Animal Quest – RTP 96.11%

• Anubis' Moon – RTP 96%

• Bandit Bust Bonus Buy – RTP 96%

• Battle Rooster – RTP 96.01%

• Battle Tanks – RTP 94% (normal 96)

Fugaso showed excellent results. All tested slots met their maximum declared RTP values, no decreases were recorded. It turned out to be quite safe to play slot machines from this provider in the casino.

• Almighty Hot Wins – RTP 96.50%

• Book Of Midas – RTP 96%

• Book Of Anime – RTP 97%

• Cash Busters – RTP 97.30%

• Deluxe Fruits 100 – RTP 96.50%

• Devil's Diamond Rush – RTP 96.30%

GameArt also showed itself on the positive side. All tested machines kept the RTP around 96%, which indicates that fair conditions for players are maintained.

• 10 Lucky Sevens – RTP 96.14%

• 20 Hot Super Fruits – RTP 96.29%

• 20 Super Sevens – RTP 96.65%

• 5 Lucky Sevens – RTP 96.11%

• 7s Fury 40 – RTP 95.99%

• Big Fruit Show – RTP 96.34%

Gamzix confidently showed good results. In none of the slots did we notice an underestimation of the RTP. The provider offers stable conditions for its users.

• 3x3 Hold The Spin – RTP 96.09%

• 40 Sweet Fruits – RTP 96.01%

• Bonanza Donut – RTP 96.73%

• Book Of Cairo – RTP 96.1%

• Buffalo Ice – RTP 96.32%

• Dogs And Tails – RTP 96.02%

Unfortunately, Hacksaw Gaming seriously disappointed in this testing: almost all tested slots recorded a noticeable decrease in RTP. Almost every slot instead of the standard 96% was around 94%, which deprives players of a significant part of possible winnings.

• Amazing Miceketeers – RTP 94.25% (normal 96.3)

• Aztec Twist – RTP 96.36%

• Barrel Bonanza – RTP 94.32% (normal 96.31)

• Blade Master – RTP 94.25% (normal 96.23)

• Born Wild – RTP 94.25% (normal 96.2)

• Buffalo Stack'n'sync – RTP 94.38% (normal 96.36)

Kalamba Games stood out pleasantly from the others: we did not notice any decreases in the slots of this provider. All slots worked at full efficiency, and in some cases even exceeded the usual 96%, which is rare in today's checks.

• 9 Blazing Cashpots 50k – RTP 95.49%

• 9 Blazing Cashpots – RTP 97.06%

• Age Of Dragons – RTP 96.76%

• Age Of Huracan – RTP 96.62%

• Age Of Ice Dragons – RTP 96.76%

• Agent 51 – RTP 96.17%

The situation with Mascot Gaming looks depressing. Absolutely all tested slots turned out to have an understated RTP. Indicators are below 93%, while the normal level should be around 95% and above.

• 243 Fruity Zen – RTP 92.13% (normal 95)

• Across The Universe – RTP 91.57% (normal 95.1)

• Aloha! Tiki Bar – RTP 93.18% (normal 95.2)

• Bamboo Bear – RTP 92.04% (normal 97.2)

• Bastet And Cats Deluxe – RTP 91.77% (normal 95.69)

• Benny's The Biggest Game – RTP 92.36% (normal 95.4)

With Pragmatic Play, the situation also leaves much to be desired: all tested machines showed reduced RTP rates. And we are not talking about one or two slots, but about a system decrease in all proven examples.

• 3 Buzzing Wilds – RTP 94.05% (normal 96.03)

• 3 Dancing Monkeys – RTP 94% (normal 96.00)

• 3 Genie Wishes – RTP 94% (normal 96.53)

• 3 Kingdoms Battle Of Red Cliffs – RTP 94.01% (normal 96.5)

• 5 Lions – RTP 93.99% (normal 96.50)

• 6 Jokers – RTP 94.53% (normal 96.51)

Push Gaming looked decent, but it was not without a fly in the ointment: one slot still showed a decrease in RTP. In the rest of the machines, the return rate corresponds to the standard values of about 96%, which gives players a good chance of winning.

• 10 Flaming Bisons – RTP 96.26%

• 10 Pharaohs – RTP 94.47% (normal 96.36)

• 10 Swords – RTP 96.45%

• Big Bam Book – RTP 96.26%

• Boss Bear – RTP 96.26%

• Cats Of Olympuss – RTP 96.26%

And finally, TrueLab did not cause any complaints as part of our check. All slots showed high and honest RTP rates, as stated by the manufacturer.

• 100 Hot Slots – RTP 96.04%

• Apple Crush – RTP 96.10%

• Arctic Spins – RTP 96.08%

• Aztec Legend – RTP 96.02%

• Battle Rage – RTP 96.07%

• Book Of Huli – RTP 96.33%

Analyzing the data obtained, I can honestly say that it is possible to win at Winningz casino, but with reservations. Serious reductions in RTP have been found in providers AvatarUX, BGaming, Hacksaw, Mascot and Pragmatic Play, which reduces the overall attractiveness of the casino. At the same time, many other providers, such as Evoplay, Fugaso, GameArt, Gamzix, Kalamba, and TrueLab, have maintained fair playing conditions. Bottom line: if you choose slots from proven honest providers, the chances of winning are preserved and it all depends on luck. But if you accidentally get into a slot with a reduced RTP, it will be extremely difficult to beat the casino. I advise you to be careful about the choice of provider and carefully study the RTP before starting the game.

It promotes itself as a crypto-friendly platform that also caters to fiat players from Canada and Ireland. The welcome package is generous on paper — 100% up to €1,000 plus 100 free spins — but as we dig deeper, we found there are important caveats. Despite having a vast library of games and slick interfaces, there are underlying issues players should be aware of before committing real money.

Winningz Casino operates under a Curacao Gaming Control Board license — certificate number OGL/2024/1788/1030. While Curacao has recently revamped its regulatory standards, it still falls short of the strict consumer protections offered by more reputable bodies like the MGA or UKGC. Although the updated framework supposedly strengthens financial oversight and responsible gambling, the lack of mandatory tools for self-exclusion or deposit limits is concerning. Security-wise, SSL encryption is used across the site, but the slow complaint resolution period of up to 90 days is a red flag.

With over 5,000 games from 51 different providers, Winningz Casino clearly delivers in terms of variety. Players can enjoy everything from Megaways and Hold & Win slots to table games and live dealer titles. Popular developers like Pragmatic Play, Microgaming, and Evoplay are well-represented. That said, the live casino lobby feels underdeveloped, featuring only a handful of studios such as Pragmatic Play Live and BetgamesTV. For high rollers or players who enjoy a full spectrum of live games, the selection may feel limited and repetitive.

The welcome bonus is presented as a major attraction — a 3-part deal totaling 225% up to €5,000 (or CAD equivalent) plus 500 free spins. However, the wagering requirements are steep at 45x the bonus amount, and bonus rules are layered and at times inconsistent. Daily promotions like mystery bonuses, reloads, and cashback exist but rarely offer substantial value. The loyalty program is slow to progress and offers low cashback percentages even at high tiers, such as just 3% at the highest VIP level. Worse, some tiers still require players to wager cashback winnings.

Winningz supports both fiat (EUR, CAD) and multiple cryptocurrencies (BTC, ETH, USDT, XRP, etc.), making it appealing to a modern gambling audience. Deposits are fast and smooth, but the same can’t always be said about withdrawals. The pending time can stretch up to 72 hours, and KYC checks, though automated, may delay the first cashout. Withdrawal limits are reasonable at €20,000/month, but high-stakes players might find these restrictive. The casino enforces a 1x turnover on deposits before withdrawals, which is standard but worth noting.

Support is available via live chat and email, but only intermittently efficient. During our review, response times varied widely — from under 5 minutes to over an hour. The FAQ section is brief and covers basics, but doesn't dive into deeper policy explanations. While some self-help options exist, they’re hidden in the footer and aren’t easy to access. This makes navigating problems more frustrating than it should be.
