UnionBet Review
UnionBet is a new online casino, and it offers a gaming site that’s well set up for international players. The whole website is easy to use, you can play with a familiar currency, and you can use traditional payment methods. The site also looks elegant, with dark tones accented by purple, and it’s well organised so you can find your way around with ease.
One of UnionBet’s biggest draws is its no-sticky welcome bonus, which doubles your deposit. As an active player, you can also take advantage of various bonus offers through the in-house store, and there are of course promotions for both casino games and sports betting.
Game-wise, you can expect just over 3,500 casino games, supplied by 37 carefully selected providers. The sportsbook is also strong, letting you place pre-match and live bets across all the most popular sports and leagues.
UnionBet provides a safe playing environment thanks to a gaming licence from the Kahnawake Gaming Commission, ensuring fair play and proper data protection.

Bonuses and Promotions at UnionBet
Both new and existing players can take advantage of casino bonuses and other perks at UnionBet, with offers covering both casino games and sports betting. Let’s take a look at what’s in store for you:
Welcome Bonus for New Players
As a new player at UnionBet, you can claim a no-sticky welcome bonus that doubles your money. On top of that, you’ll also receive free spins every day for 10 days. Here’s what your UnionBet welcome bonus includes:
- 1st deposit: 100% bonus up to €500 + 200 free spins
– min. deposit: €20
You’ll get 20 free spins per day, over 10 consecutive days. The first 20 spins are credited as soon as your deposit is made, and the remaining ones are added in 24-hour intervals. The spins can be used on the following slots: Sweet Bonanza 1000, Zeus Vs. Hades – Gods of War, Reactoonz, Money Train 4, Gates of Olympus 1000, Big Bass Bonanza, Royal Coins 2 Hold and Win, Book of Power, Bill and Coin 2, and Sweet Rush Bonanza.
Comparing this welcome bonus to similar offers at other casinos, UnionBet stands out positively in two ways: the bonus is no-sticky, meaning your own funds aren’t tied to the bonus, and the free spins are awarded on popular slots, often with a value of €0.20 per spin instead of the usual €0.10.
The welcome bonus from UnionBet is solid and well worth claiming because it’s no-sticky and the free spins carry a high value.
Bonus Terms for the UnionBet Welcome Bonus
You start out playing with your own funds, and if you win you can choose to cancel the bonus and withdraw your winnings. If your own funds run out, however, you’ll then start playing with bonus money, which is tied to a wagering requirement. To convert the bonus into real money, you’ll need to wager it 40 times, while the wagering requirement on free spin winnings is just 30x. The maximum bet per round when using bonus money is €5, and there’s no cap on withdrawals.
Alternative Welcome Bonuses
If you prefer sports betting over casino games, there’s a sports welcome bonus you can take advantage of. With this offer, you’ll receive either a €50 or €100 free bet. Here’s how it breaks down:
- Deposit €50 – €99: Get a €50 free bet
- Deposit €100 or more: Get a €100 free bet
The minimum odds you can use your free bet on are 1.80. The full free bet amount must be placed on a single bet, and if you win, your winnings will be paid out as cash with no wagering requirements attached.
In addition to your free bet, you’ll also get boosted odds on a selected match. You’ll be able to see which one once your deposit has been made.
Ongoing Promotions and Bonus Shop
Beyond the welcome bonus, there aren’t all that many ongoing casino promotions to take part in. The only standing offer listed on the site is a 10% cashback on net losses. That said, you can also claim bonuses through the shop, using coins you collect by playing. In the bonus shop, you can choose between free spins on various slots, bonus money, or cash.

There are no fixed reload bonuses for sports betting either. The offers you can take advantage of include acca boosts, free bets, and early payouts.
Deposits and Withdrawals at UnionBet
The selection of payment methods at UnionBet isn’t particularly extensive. They don’t support cryptocurrency, and there are no e-wallets available either. That means deposits can only be made using Visa and Mastercard. Alternatively, you can use a Revolut card or pay via Apple Pay or Google Pay. Bank transfer is also supported, both for deposits and withdrawals. It’s worth noting that when you use Revolut, your card is used for deposits, while withdrawals are sent to your Revolut account.
When it comes to transaction limits, the minimum starts at €20, both for deposits and withdrawals. This is fairly standard compared to other casino operators. The maximum limits, particularly for withdrawals, are however set on the lower side. You’ll find all transaction limits and an overview of available payment methods in the table below.
| Payment method | Limits | Transaction time | Limits | |
|---|---|---|---|---|
| Deposit | Withdrawal | |||
| Visa & Mastercard | €20 – €2,350 | Instant | – | – |
| Revolut | €20 – €2,350 | Instant | €20 – €2,900 | 1–3 days |
| Apple Pay & Google Pay | €20 – €1,700 | Instant | – | – |
| Bank transfer | €20 – €2,350 | Within 24 hours | €20 – €2,900 | 1–3 days |
Withdrawals, Verification, and Payout Limits at UnionBet
UnionBet is a fast-payout casino, where you can expect all withdrawal requests to be processed within 24 hours. How long it takes for the money to actually reach you can vary, since bank transfers (the only available withdrawal option) can take anywhere from a few hours to a few days.
The limits on how much you can withdraw per day, week, or month aren’t disclosed. UnionBet does, however, reserve the right to cap payouts at €20,000 per 30-day period. This is decided at their discretion, so be prepared for large winnings to potentially be paid out over several months.
Before you can make your very first withdrawal, you’ll need to verify your account. This is done by completing a KYC verification, which requires you to confirm both your identity and your address. You may also be asked to verify that the payment methods used for deposits and withdrawals legally belong to you.
To make sure the KYC process goes as quickly as possible, it’s important to follow the document requirements carefully. That means making sure all corners of the documents are visible, that your ID is valid, and that your proof of address has been issued within the last 3 months.
Games at UnionBet
Looking at the game library at UnionBet compared to what you’ll find at other online casinos, the selection here is fairly modest. The casino only offers just over 3,500 casino games, split between RNG titles and live dealer games.
There are only three categories in the casino game menu: Slots, Crash Games, and Table Games. However, if you head into the lobby and scroll down the page, you’ll find a number of additional subcategories. You can choose between Bonus Buy, The Book Always Wins, Megaways, All About the Bass, Joker, The Wildest West, Egypt, High Variance, Medium Variance, Asia, Crash Games, and Jackpots.
The relatively small casino game library is partly offset by the fact that UnionBet also offers sports betting. In fact, we’d argue the sportsbook is the strongest aspect of the overall game selection.
Game Providers
The reason the casino game selection is so limited is that very few game providers are featured. UnionBet has chosen to partner with only 37 of them. This means there’s no guarantee your favourite providers will be available at this casino.
That said, we have to give UnionBet some credit for putting together an interesting mix of providers. Rather than only offering games from the biggest names, they’ve also included a number of smaller and up-and-coming studios. So you can find games from names like Pragmatic Play, Play’n GO, Hacksaw Gaming, Relax Gaming, and Betsoft, alongside Avatar UX, Backseat Gaming, PenguinKing, Armadillo Studios, and Shady Lady.
Slots and Jackpot Games
It’s impossible to pin down exactly how many slots are in the library, since you can’t view the full selection in one list. We’d estimate around 3,000 of them, however. What is certain is that you’ll find both simple, classic slots and complex, modern video slots. That gives you access to just about every game mechanic and bonus feature you can think of.
Even though not every type of slot has its own category, we appreciate the way UnionBet has organised things. The fact that they’ve created categories based on game type and mechanic, as well as theme, is a nice touch and something we’d love to see more casinos do.
If you want to play jackpot games, you’ll find 30 of them in the dedicated category. That’s a small selection, far below what we’re used to seeing elsewhere. We were also disappointed that only fixed jackpots seem to be on offer, as we didn’t recognise any titles featuring a progressive jackpot. The jackpot games might just be the most disappointing aspect of UnionBet.
Live Casino and Table Games
You’ll find live games from Evolution and Pragmatic Play, with a total of 200 titles listed in UnionBet’s live casino. Although we’d usually prefer to see more live studios on board, these two are the biggest in the industry, so that’s a solid foundation. Together, they cover all the popular table games as well as an exciting range of game shows.
There are four categories in the live casino menu: Roulette, Blackjack, Game Show, and Baccarat. If you scroll further down the lobby, you’ll also come across two additional game types: poker and dice. This works well, as long as you’re after one of the more common game types. If you’re looking for something else, like Andar Bahar or Bac Bo, finding it isn’t quite as intuitive. You’ll need to use the search bar to track down the specific titles you want.
Sports Betting and Odds
There’s not much to fault about UnionBet’s sportsbook, as it’s actually pretty strong. You’ll find a list of more than 25 different sports, with markers indicating which ones offer live betting. Beyond the sports themselves, the biggest leagues and tournaments are also prominently displayed, so you can easily check odds for matches in the Premier League, La Liga, NHL, NBA, the Australian Open, the EHF Euro, or the World Cup.
All the usual sports are represented, led by football. Hockey, tennis, basketball, handball, esports, and table tennis round out the most popular options. If you choose to bet on live matches, there are plenty of betting markets available, but you’ll need to be quick when placing your bets, as the odds are dynamic and constantly changing.
Licence, Security, and Responsible Gambling
UnionBet is a new online casino owned and operated by DCentral Enterprises S.R.L. The company is registered in Costa Rica and licensed in Canada, through the Kahnawake Gaming Commission. This gaming licence is well-recognised in the industry, and it places strict requirements on casino operators, particularly regarding data security and fair play. That means players can enjoy a safe gaming experience at UnionBet, with all games certified and approved.
UnionBet also makes it easy for you to play responsibly. By heading to your account profile, you can set a deposit limit that controls how much you can deposit per day, week, or month. The limits take effect immediately, and if you later choose to lower the limit, that change will also apply right away. To raise the limit, however, you’ll need to wait 7 days.
You can also pause or close your account, but only by contacting customer support. You can put your account on hold for one or seven days, or close it for two, three, or six months. If you opt for a self-exclusion, your account will remain closed unless you reach out and request to reopen it after the self-exclusion period has ended.
User Experience and Mobile Play
Navigation on the UnionBet website is generally good, as it’s easy to find your way around the various services and game categories. The site also supports euros as a currency, which is convenient for international players.
What isn’t quite as good is the fact that you can’t view the entire game library in one place. Plenty of categories have been added, but seeing every title at once isn’t possible, so a complete overview is missing.
Playing on mobile, however, is no problem at all, as the experience is very similar to the one you get on a larger screen. You always play through the browser on your phone, and the site adapts to your screen size. Since no extra software or app is required, both iPhone and Android users get the same smooth experience.
Customer Support at UnionBet
The live chat at UnionBet is available 24/7, so you can always get quick help. Every time we tested the chat, we got assistance within just a few minutes. Another option is to send an email, but this contact method takes a bit longer. When we tested email support, it took around an hour to receive a response.
During our UnionBet test, we reached out four times: three times via chat and once by email. We asked both straightforward and tricky questions to evaluate the knowledge of the support agents we spoke with. The answers we received were thorough and the agents were friendly. Some of the more common questions were met with pre-written standard replies, but for the most part the agents seemed to provide tailored responses.
How We Tested UnionBet
We tested UnionBet using Kingbonus’ standard methodology for online casinos. We did this to make sure we covered every aspect of the casino and could provide a review that’s as objective and accurate as possible. Here’s a breakdown of what we did:
- Terms of service and registration: Reading through the terms and conditions is always our first step. After that, we created a player account, both to see what the process is like and to have an account to use throughout the rest of the test.
- Welcome bonus: We claimed the welcome bonus by depositing €50. We then started playing to verify that the bonus really is no-sticky. Unfortunately, we weren’t able to clear the wagering requirement. As part of the bonus testing, we naturally also read through all bonus terms and reviewed the ongoing promotions on offer.
- Deposits, withdrawals, and KYC: A total of four deposits were made. We first used a Visa card and then made three deposits with our Revolut card. Two withdrawals were processed, and both went to our Revolut account. The KYC verification was also completed.
- Games and casino lobby: We tried all the different game types at UnionBet, though we mostly stuck to slots. We also did a thorough walkthrough of the various categories, including the game providers.
- Customer support: We contacted the customer support team four times. We tested the agents’ knowledge and also evaluated response times, the quality of their answers, and how friendly and welcoming they were.
- Responsible gambling tools: Responsible gambling was tested mainly by reviewing the tools on offer and the information available on the site. We didn’t actually set any playing limits, as we wanted to keep the account open for further testing.
Who Is UnionBet Best Suited For?
UnionBet is a solid online casino, but even the best casinos aren’t right for every player. Below you’ll find our take on which types of players UnionBet suits best and which it suits least.
Best suited for:
- Players who want fast withdrawals of their winnings
- Players who want to claim true no-sticky bonuses
- Players who prefer to use traditional payment methods
Less suitable for:
- Players who prefer to use cryptocurrency
- Players who want a large game selection
Our Verdict and Rating of UnionBet
After a thorough review and test of UnionBet, we can conclude that this operator has plenty of strong points. First and foremost, we’d highlight the no-sticky welcome bonus, which lets you claim the offer risk-free. We also like that the sportsbook is as solid as it is, and that the security is reliable thanks to the Kahnawake licence. The fast withdrawals are another big plus we want to mention as one of UnionBet’s strengths.
That said, there are some downsides too. What stood out most to us was the limited game selection. 3,500 casino games is just a fraction of what you’ll typically find at the top online casinos. The 40x wagering requirement is also on the high side, and many players will likely miss having regular reload bonuses. Perhaps the biggest drawback at UnionBet is that they don’t support cryptocurrency or e-wallets for deposits and withdrawals.
Overall, we can recommend UnionBet as a solid online casino, but it likely won’t suit every player. If having access to a wider range of payment methods and a larger game library matters to you, we’d suggest checking out other operators in our casino list.
