Big Boost Review

Big Boost is an online casino offering more than 7,700 casino games, including a live casino. You can find a wide range of slots, table games, specialty games, and not least many of the very biggest jackpots online. As a new player, you’ll also get off to a great start with Kingbonus’ exclusive no-sticky welcome bonus that both doubles your money and gives you 200 free spins. 

The Big Boost website is also user-friendly, so you won’t have any trouble finding your way around the various services and games. You can play with EUR as your account currency. Your deposits, however, can be made with both regular payment methods and cryptocurrency. 

The licence Big Boost operates under is from the gaming authorities in Curaçao. If you need help, you can get it around the clock, both via email and live chat.

Big Boost online casino will be particularly well suited for players who prefer playing with real money and who like to use cards for deposits and bank transfer for withdrawals.

Bonuses and Promotions at Big Boost

At Big Boost, you can get a great start to your gaming experience by claiming an exclusive bonus only for players who sign up via the Kingbonus link. Beyond this, you can expect offers via email or SMS, so make sure you’ve opted in to accept communication from the casino. Let’s take a look at the various casino bonuses Big Boost offers.

Welcome Bonus for New Players

The exclusive welcome bonus from Big Boost is available by clicking the “Claim Bonus” button on this page. You’ll then get a no-sticky bonus that gives both a match bonus and free spins. Here’s the offer:

  • 1st deposit: 100% bonus up to €1,500 + 200 free spins
    min. deposit: €20

All free spins are credited on the slot Book of Dead from Play’n GO. This is one of the most popular video slots of all time, and the value per spin is €0.10. To play them, you’ll need to activate the bonus from the “Rewards” section of your player account.

It’s the no-sticky bonus mechanic that makes the welcome bonus from Big Boost good. No-sticky means the bonus money is kept separate from your own real money, so your deposit isn’t tied up in bonus terms or specific requirements. The fact that you also get 200 free spins is good, even though the value per spin is on the low end of the scale.

If you want to claim a bonus without tying up your own deposit, the no-sticky welcome bonus from Big Boost is a good choice.

Bonus Terms for the Big Boost Welcome Bonus

The welcome bonus from Big Boost is no-sticky, which means you don’t start wagering the money until after you’ve lost your own deposit, if it comes to that. The wagering requirement that must be cleared before the bonus money is converted into cash is 35x. The maximum bet while playing with bonus money is €5 per round. There’s no limit set on how much you can win from your bonus.

Ongoing Promotions and Loyalty Programme

There are surprisingly few ongoing casino offers at Big Boost. The promotions section on their site is fairly full, but for the most part it’s information about tournaments, payment methods, or other forms of news they post there. 

The only recurring casino bonus we found was a 10% cashback offer. This offer is only available on Thursdays, and also only applies to deposits you make on that day. The bonus money you get will be credited on Friday, and the wagering requirement is set at 10x.

Big Boost Exclusive
The Big Boost promotions section shows various forms of news, and you can also find information about the weekly cashback bonus.

There’s no loyalty programme either, but that doesn’t mean you’ll never get bonus offers at Big Boost. If you want something extra, you’ll instead need to make sure you’ve opted in to receive promotional offers via email. You’ll then get bonuses based on your player segment, which means VIP players can get bonuses tailored to high rollers. 

Deposits and Withdrawals at Big Boost

There’s a fairly good selection of deposit methods at Big Boost, and you can use Revolut, regular bank cards, e-wallets, a prepaid voucher, and cryptocurrency. The selection of withdrawal methods, however, is far smaller, as only bank transfer and cryptocurrency are available when you want to withdraw money. So if you’ve used a fiat method to deposit money, you’ll need to use bank transfer to withdraw your winnings. 

When it comes to transaction limits, these are flexible. The minimum deposit is either €10 or €15, while the maximum goes up to at least €2,500. The minimum for withdrawals via bank transfer is €40, which is higher than the minimum for fiat withdrawals at most online casinos. In the table below, we’ve put together an overview of transaction limits and expected transaction times.

Withdrawals, Verification, and Payout Limits at Big Boost

At Big Boost, the withdrawal rules include a maximum cap of €100,000 in winnings per day. If you win more than this, the excess amount will be removed from your account. This limit applies to all players, with the exception of players considered true VIP players by the casino’s management. Winnings stemming from progressive jackpots are also exempt from the rule. 

Other winnings can be withdrawn as long as you’ve wagered your deposit at least once. Generally, the casino will process withdrawals within 24 hours, but if there’s high demand it can take up to 48 hours. The applicable withdrawal limits can be found in this table:

Withdrawals per dayWithdrawals per weekWithdrawals per month
€5,000€20,000€50,000

To get fast withdrawals from the casino, your player account needs to be verified. This process can be completed in just a couple of minutes. You’ll receive information about which documents the casino requires from you, and then you upload them directly to your player account. Alternatively, you can also send them via email. 

All players will be asked to verify their identity and home address. In addition, you may be asked to verify deposit and withdrawal methods. If you’ve used a Visa card for deposits and withdraw winnings to your bank account, you’ll need to submit an image of your Visa card (with sensitive information covered) and a bank statement showing your name and account number. Exact information about what should be shown and what should be covered will be provided as soon as the casino asks you to complete the verification.

Games at Big Boost

The Big Boost casino holds 7,700 casino games, the vast majority of which are slots. There are, however, also other game types, such as RNG table games, crash and mine games, scratch cards, and other specialty games. In the casino lobby, you’ll find many different game groupings, and they’ve chosen to sort games by game type, features, and prize pot. 

Beyond RNG casino games, Big Boost also has a live casino, where you’ll find games from a range of studios. You can play all the classic table games as well as modern variants of live dealer games. In the live casino too, the games are split into logical categories so you can see the entire selection of the game type you’re after.

Game Providers

Among the 104 game providers at Big Boost, there are both big, well-known names and smaller or recently launched providers. This gives an interesting selection that covers the vast majority of game types and provides good variety in terms of volatility, bonus features, game mechanics, and other aspects that each of the various providers focuses on to a greater or lesser extent. 

The studios Big Boost lists at the top of its provider overview are Play’n GO, Relax Gaming, Inspired, Kalamba Games, Hacksaw Gaming, and Push Gaming. If you have a favourite, you can choose to view only their games, and you’ll find filtering by provider by selecting Studio in the search field.

Slots and Jackpot Games

You’ll find slots in the vast majority of the game groupings in the menu. If you want to try some of the most popular titles, you can look in the Recommended, New Releases, Popular Games, or Local Favourites categories. For special features, you can try the Bonus Buy, Megaways, Epic Wins Over 10,000x, or Drops & Wins categories. This game grouping means all players should be able to find the slots they like best. 

There’s also a dedicated category for jackpot games, where you’ll find several of the world’s very biggest progressive jackpots on online slots. For example, there are a number of games in the Mega Moolah series, where the jackpot at the time of writing is more than €11 million. If you prefer the WowPot games, you can now win more than €2 million. It’s easy to identify the games with the biggest prize pots, as each title is marked with a jackpot sum. 

Live Casino and Table Games

The live casino has more than 500 games, supplied by studios like Evolution, OnAir Entertainment, Pragmatic Play, Stakelogic, Ezugi, and Inspired. Even though only a few of these have a truly large selection, having several on board is important for quality. Each studio has its area of specialty, and together they create a variety that’s impossible to achieve with fewer providers. 

The game grouping is also good, and you can choose between the categories Popular Live Games, Roulette, Game Shows, Live Poker, Blackjack, Lottery, Baccarat, Dice Games, Other Live Games, Drops & Wins Live, and All Games. Within the table games, you can expect to find all the traditional games with classic rules, as well as modern variants played with different rules or some form of bonus features. 

Licence, Security, and Responsible Gambling

It’s the Curacao Gaming Control Board that has licensed Big Boost. The licence itself, with licence number OGL/2023/159/0076, is issued to White Star BV., the company that owns and operates the casino. This licence is considered one of the safer ones available. Some of the licensing requirements are that the casino must keep player funds separate from its operating accounts, that the games must be fair, and that the casino must have responsible gambling tools.

To ensure fair play, the providers they work with must be licensed, and the games must be certified as fair by third-party testing companies. The casino’s software and random number generator must be certified in the same way. Big Boost meets these and all other requirements set by the Curacao Gaming Control Board.

Responsible gambling is a topic that has been given a dedicated page at Big Boost. There you’ll find information about what it means to play responsibly and tips on how to stay in control while gambling. Players who have a problematic relationship with gambling can also find a link to support organisations.

When it comes to responsible gambling tools, unfortunately there isn’t much on offer. You can activate a pause on your account or choose to self-exclude. There’s no option to activate a playing limit, such as a deposit limit or loss limit, however. 

User Experience and Mobile Play

The Big Boost website itself supports EUR as a currency to cater even more to its players. It’s also easy to navigate the site, so you intuitively find your way to the games and services you’re after. The game categorisation is also good to start with, even though we would have liked a few more groupings based on game type. 

The experience you get playing from mobile is roughly the same as from desktop. You use the same website, and this will adjust to fit your screen size. The navigation is laid out slightly differently, but still very user-friendly. All games are available for all types of devices, and as long as you have a good and stable connection, you can play without disruptions like stuttering or slow loading.

Customer Support at Big Boost

You can get help at any time at Big Boost, and the fastest method for getting in touch with a support agent is by using the live chat. In addition, you can send an email, but you should then expect a somewhat longer response time. Note that the customer support contact details are a little hidden. Go to the help section on the site, click into a question, and then choose the option to get in touch below the answer. 

To test customer support, we got in touch four times; twice per contact method. Via the chat, we got a reply within one minute, while it took 20 minutes and almost 3 hours respectively to get a reply via email.

The purpose of contacting customer support was to test their response time, knowledge, and willingness to help us. We asked about various aspects of KYC verification and withdrawals, responsible gambling and various tools, and generally about security and licensing. The help we received was good, and the agents we were in contact with were friendly, even when we asked slightly awkward questions. For the most part, it seemed like we got personal answers, and not just pre-written standard replies.

How We Tested Big Boost

We tested Big Boost using Kingbonus’ standard methodology for online casinos. This methodology is designed to ensure a thorough casino test of every aspect, with a full 24 test aspects being examined. Below, we’ve described some of the most important aspects we tested.

  • Terms of service and registration: All rules and terms were read and compared against the industry standard. In particular, we looked for deviations that are unfavourable for players. We also signed up as a player so we had an active player account for the rest of the test.
  • Welcome bonus: We used the exclusive welcome bonus, but kept to a deposit of €50. We also reviewed the promotions section and took a thorough look at all the bonus and promotional terms.
  • Deposits, withdrawals, and KYC: Revolut, Visa, and the cryptocurrency Tether were the payment methods we used for our six deposits. We also made one withdrawal, to our Tether wallet. To be able to make a withdrawal, we also verified the player account. 
  • Games and casino lobby: The game portfolio was carefully reviewed, and we evaluated the selection in each of the categories offered. In addition, we took a thorough look at all the game providers.
  • Customer support: Contact with customer support was made four times, and we used both the live chat and email. We asked questions of varying difficulty to evaluate knowledge, friendliness, response time, and the quality of the answers we received.
  • Responsible gambling tools: We chose not to activate a pause or self-exclusion on our account, since we needed access to be able to carry out our test. So we limited ourselves to reading through the responsible gambling page and asking the support agents for advice about the pause function.

Who Is Big Boost Best Suited For?

Big Boost is a casino site that suits quite a few players, but also lacks some aspects that are important to others. Our assessment of which types of players should choose Big Boost and which should look for a different online casino can be found here:

Best suited for:

  • Players who want an online casino with a user-friendly site
  • Players who are primarily interested in playing slots
  • Players who want fast withdrawal processing and good withdrawal limits

Less suitable for:

  • Players who want more options for withdrawing winnings
  • Players who want a better selection of regular promotional offers

Our Verdict and Rating of Big Boost 

Big Boost is an online casino with many good aspects. We’re particularly pleased that their welcome bonus is no-sticky and that the website is well suited to its players. The fact that the gaming licence is safe and that customer support is good is also something we appreciate. Furthermore, we have to say that the categorisation of slots is good and that it’s great to see they offer many of the web’s very biggest progressive jackpot games. The fact that withdrawals are mostly processed within 24 hours is also a big advantage.

Among the downsides, it’s first and foremost the limited selection of withdrawal methods that’s disappointing. We also have to point out that the total game selection is smaller than what the vast majority of online casinos offer. The fact that there’s no option to limit deposits, losses, or session time is also a drawback we noted.
