BiggerZ Bonus Offers

The available promotions at BiggerZ are divided into casino and sports sections. I noticed that there are not plenty of fixed offers, as the operator seemingly focuses on tournaments and competitions. Here is a short overview of the available offers at BiggerZ.

BiggerZ Betting Offers

BiggerZ has a sports first deposit bonus and a combo boost feature that boosts the odds if certain criteria are met. During big tournaments, you can also expect the operator to launch tournaments. For example, when I was reviewing the operator, the World Cup 2026 was active, and there was a competition with a $1,000,000 prize pool shared across 1,000 players who had placed the most successful bets on it.

BiggerZ Betting Welcome Bonus

New bettors who register and deposit at least 20 USDT will be eligible to get a 50% OnlyWin Freebet of up to 500 USDT. “OnlyWin” means that if the bet is won, punters receive only the winning amount, without any wagering requirements attached. The free bet can be used on all events and betting markets, but odds need to range between 1.30 and 2.0. 

BiggerZ Free Bets

Apart from the betting welcome bonus, there are no other fixed promotions that include free bets at BiggerZ. The only additional feature available is enhanced odds, through which punters who place combo bets of at least three events can get boosted odds. Total eligible odds must be 1.30, and the odds boost depends on the number of selections.

BiggerZ Casino Offers

The casino section at BiggerZ has a first deposit bonus, a 50% cashback for VIP Players and a referral bonus as fixed offers. There are no free spins or reload bonuses for players to claim, but there are several ongoing tournaments, including Pragmatic’s long-standing Drops & Wins.

BiggerZ Casino Welcome Bonus

Players who register and deposit at least 10 USDT can get a 150% first deposit bonus of up to 1,500 USDT. A promo code “WO” needs to be used apart from making the qualifying deposit. Wagering requirements of 40x apply to the offer, and it is valid for 14 days before expiring.

BiggerZ Casino Free Spins

At the moment of writing this review, I didn’t find any free spins promotions at BiggerZ. The T&Cs of the operator have a section where it is stated that free spins may be offered as rewards to a certain category of players, but I didn’t receive such prizes during my live tests.

BiggerZ VIP Cashback

VIP players who make deposits worth at least 5,000 USDT during the week at BiggerZ will be eligible for a 50% cashback up to 500,000 USDT. This cashback bonus for casino players comes with 3x wagering requirements. 

BiggerZ Referral Program

All registered players will have a unique referral link that they can send to friends. Once they register and make a deposit of at least 60 USDT, referrers can get a 20% bonus of up to 50 USDT. The referred friend will also get a 10% offer on their first deposit. Bonuses part of the referral program come with 40x wagering requirements and are valid for 7 days.

Rakeback and Cashback for Regular Players at BiggerZ

Players’ loyalty levels will determine their daily and weekly cashback deals. Users at the first, Beginner, level will be eligible for 2% and 3% daily and weekly cashback, respectively. As they climb the VIP ranks, they can get up to 15% and 10% daily and weekly cashback. As for the rakeback deal, it is up to 7%, regardless of the current VIP level.

BiggerZ Arena

The BiggerZ Arena is where all daily missions, tournaments, and Weekly Races are stored. These competitions can frequently change, but just so you know what you can expect, here are a few active leaderboards at the moment of writing this review:

• Weekly Race: Players who opt for the Weekly Race can earn Coins through missions and campaigns to climb a leaderboard. The prize pool is 100,000 USDT.
• Drops & Wins: Any Pragmatic slot is eligible for this tournament, for which the prize pool is 2,000,000 USDT every month. Players need to bet 0.2 USDT on games to participate.

• Challenges: Completing sports and casino challenges set by the operator can see users get bonus money and Coins. Some of the example challenges include placing single bets on over/under markets, making a certain number of spins on a slot game, or placing eligible bets on a current competition. Coins can be exchanged for prizes in the Store.

BiggerZ Design & UX

By testing BiggerZ’s website, I instantly noticed the modern, minimalistic design without any flashy colours and overcomplicated features. The menu on the left side contains all the most important features and sections of the operator, such as game library shortcuts, promotions, tournaments, and challenges. 

On the top of the homepage, BiggerZ displays all its bonus banners in a moving menu, and just below them, there are interactive sections for Casino, Sport, and Predictions, which show how many active users visit them.

I noticed one small issue in the game lobby interface. The game categories, alongside the Search bar, are on top of the game icons. Now, there is no navigation arrow to browse these sections, which are blocked by the Search tab. 

This fails to signal to players that additional game categories exist beyond the few displayed ones, which leads to poor discoverability. I hope it is just a temporary bug which will be fixed in due course.

BiggerZ Mobile App

BiggerZ has a progressive web app that can be installed on any Android or iOS device. Once you open the operator's website on mobile and scroll down the main menu, you will notice a "Download App" button. Tap on it, and a short guide will appear on how you can install the app and add it to your homescreen. This is not a native app; there are no performance issues I can report. As far as mobile casinos go, BiggerZ ticks all the major boxes.

BiggerZ Customer Service

Customer support at BiggerZ is available via live chat and email. I tested the former, and the agents lived up to my expectations. After entering my name and email address, I was asked to choose a language and explain my issue. Once I did that, an agent joined the conversation and provided a timely response. An interesting feature I discovered on the site is called “Guide”, where users can find useful information on World Cup betting news, crypto gambling guides, and game suggestions.

BiggerZ Casino Payment Methods

BiggerZ Casino predominantly accepts cryptocurrencies as payment methods. The likes of BTC, LTC, BCH, ETH, USDT, and USDC are among the supported options, and the minimum deposit is 5 USDT. 

The casino also allows users to "buy crypto" by using fiat options like Visa, MasterCard, Apple Pay, Google Pay, and bank transfers. Players can just transfer money with these options, and BiggerZ will convert the sum into digital currencies in their accounts.

As for withdrawals, the minimum amount is 10 USDT, and there are no withdrawal commissions charged, bar one exception. If you haven’t wagered the deposited amount at least once, BiggerZ will deduct an 8% fee from the payout.

Withdrawals are usually processed instantly, but “bigger” payout requests may require additional reviewing time. The operator hasn’t specified what “bigger” means and how long these delays can take.

KYC is not asked for before players make a deposit, but ID checks are triggered before the first withdrawal. Photo ID, address confirmation, and a video call may be asked of players before their payout request is approved.

Note that you will only be allowed to withdraw to the payment method you used for deposits. If you request a withdrawal to a different option, the casino will need to approve it and conduct additional security checks.

I noticed that BiggerZ doesn't impose any maximum withdrawal limits to players, which can be a welcome sight for high rollers.

Is BiggerZ Safe?

BuggerZ is owned and operated by a company called CDK Play INC SRL. The operator is licensed by the Government of the Autonomous Island of Anjouan, and its licence number is ALSI-202504023. I was able to confirm the active licence in Anjouan’s Licence Register, where both the owner and the domain were listed. The licence was obtained in 2025, and it expires in 2027.

BiggerZ Review Conclusion

BiggerZ is a modern crypto casino with several appealing features, but it also contains some notable flaws. I was quite happy with the gamification elements on the site, such as the ongoing tournaments, challenges, missions, and leaderboards. The operator keeps up to date with all sporting developments, too, as at the moment of writing this review, I was able to participate in a World Cup 2026 leaderboard.

Still, there is no going away from the disadvantages of the operator. The user interface issues in the lobby are well-documented, and it is something BiggerZ needs to work on if it is to keep players engaged through smooth navigation. Some of the bonuses, including the casino welcome offer, have high 40x wagering requirements, which can make monetisation difficult for casual players.

I’d also like to see a few more fixed free spins or deposit matches for existing players. Overall, my experience with BiggerZ was mainly positive, and I quite liked the inclusion of unique features like "Predictions" (bets on non-sporting events) and "BiggerZ Touch” (a list of exclusive instant win games available only at this casino).
