Onnela Kasino is a new Trumo online casino operated by Simba N.V. with a Curacao license (license OGL/2024/1788/1030). The site proudly markets itself as 100% Finnish owned, with a clean minimalistic blue-yellow design.
Onnela doesn't give traditional deposit bonus instead, they offer daily 10% cashback with 10x wagering requirements. It is better on long-term.
Our Onnela Casino review goes through all the details you need to know from payments to pros & cons, so keep reading.

More info:
Instead of deposit bonuses, Onnela offers a flat 10% daily cashback.
This is straightforward but comes with strict 3-day wagering and expiry. Good for consistent players, but less rewarding for bonus hunters.
Onnela Kasino keeps things very light when it comes to promotions. At the moment, there are only two offers on the table: the 10% daily cashback and Pragmatic Play’s Drops & Wins campaign with daily tournaments and weekly prize drops.
That’s it: no reload bonuses and no free spin packs. For a brand-new casino this feels a bit barebones, but since Onnela just launched, I’ll let it slide. There’s potential for them to expand with more unique promos down the line, and for now, at least, the cashback system and Drops & Wins give active players something to look forward to.
Onnela Kasino does have a loyalty program, and it’s one of the more traditional ladder-style setups. Every €1 wagered on slots gives you 10 XP, which moves you up through different levels starting from Sinkki (Zinc) and eventually going all the way up to Timantti (Diamond. In total the program has 11 tiers.
The higher you climb, the better the perks: free spins, mega spins, and x amount of euro worth of free spins tied to your activity. For example, free spins are credited to Book of Dead (Play’n GO), but they come with the standard strings attached:
It's nice to see Onnela trying to give back through a tier system, but the wagering requirements are high and all the free spins goes to Book of Dead slot.
Onnela Kasino keeps things very simple, maybe even a too simple. The lobby is straightforward with just the essentials: Slots, Live Casino, and Promotions. Navigation is smooth, and you’ll find categories like Featured, Top Picks, and Bonus Buy that make browsing easy.
The design uses a dark-blue background with bright gold highlights, giving it a clean look without too many distractions.
On mobile, the site performs just as well as on desktop. Buttons are large, menus are minimal, and you can get from login to spinning in under a minute.
Onnela Kasino offers a solid library of over 3,500 games from 36 different providers, which is a respectable starting point for a new site. The collection covers all the basics: slots, jackpots, live dealer tables, and some instant win titles.
You won’t find every big-name studio here, though. For example, Nolimit City and Yggdrasil are missing, which might disappoint fans of those providers. On the flip side, Onnela includes some more unusual studios like Shady Lady.
A nice touch is that you can also play games for free before depositing. Just pick a slot and hit Play for Fun.
To give you an idea of the game setup, we checked the RTP values for a handful of popular titles:
Onnela Kasino’s live section is straightforward. You’ll find tables from Pragmatic Play Live, Iconic21, Live88, and Betgames TV, covering the essentials like roulette, blackjack, baccarat, and a few game shows. The big downside is the absence of Evolution Gaming, which is usually the gold standard for live casinos.
Onnela Kasino is operated by Simba N.V., a company registered in Curacao under license number OGL/2024/1788/1030. This license allows them to legally offer online casino games in many countries.
In terms of safety, the site uses SSL encryption to protect all personal and financial data, ensuring your information stays secure when depositing, withdrawing, or simply browsing. All transactions are processed through verified payment providers, and games come from recognized studios.
Onnela Casino is operated by Simba N.V., the same company behind a couple of other casinos that share a very similar look and feel. These sites use the same payment methods and overall design, making them instantly familiar if you’ve tried one of them before.
The key difference is that the sister casinos also include traditional welcome bonuses.
If you’re curious, you can check out the sister casinos listed here:
✅ 100% Finnish branding
✅ Simple cashback system, no confusing bonuses
✅ Instant withdrawals (when not under review)
✅ Easy and minimalistic site
❌ Curacao license
❌ No Evolution in the live casino
❌ Cashback has 10x wagering
❌ No responsible gambling tools
Onnela’s responsible gambling section it is not the best:
Only general advice (time limits, playing smart, etc.) and external links (GamblingTherapy).
This is a clear weak spot compared to EMTA licensed casinos or MGA. The lack of in-account tools makes it less trustworthy.
Onnela Kasino markets itself as a Finnish-friendly site with simple navigation and daily cashback. The promotions section is unfortunately really empty, but the casino is new and we believe there will be promotions. However, the lack of Evolution tables, limited responsible gambling tools, and Curacao licensing make it less competitive compared to regulated Nordic casinos.
For Finnish players who want a straightforward Trumo casino with cashback instead of bonuses, Onnela can be worth a try. But if you value tax-free winnings and stronger player protection, EMTA-licensed casinos like Kassuuu are the safer bet.
