Overview
Detailed Review
What Is Zonko and How Does It Work?
Zonko is a sweepstakes casino that launched in 2026. It is operated by Mamba Limited, a company incorporated in the Isle of Man.
Like all sweepstakes casinos, Zonko uses a dual-currency model to operate legally in most US states. You play with two types of coins: Gold Coins (GC) and Sweeps Coins (SC).
Gold Coins are for fun play only. You cannot redeem them for cash prizes. You get GC through purchases, bonuses, or daily login rewards.
Sweeps Coins are the currency you use to enter sweepstakes contests for real cash prizes. When you win with SC, you can redeem those winnings for cash. The redemption rate is 1 SC = $1.
You can get Sweeps Coins through mail-in requests (the Alternative Method of Entry or AMOE), through certain bonuses, or as part of purchase packages. This "No Purchase Necessary" method is a core legal requirement for sweepstakes casinos.
We give Zonko an expert score of 4.18 out of 5. This score is based on our analysis of its bonuses, games, banking, safety, support, and mobile experience.
As a new casino, Zonko compares to established sites like Pulsz and Stake.us. It has a smaller game library than those competitors but offers a simpler bonus playthrough requirement. Its sister site is Spinfinite.com.
Zonko Bonus & Promotions
Zonko offers several promotions for new and existing players. The bonuses are structured around the dual-currency system.
Welcome Bonus
New players receive 3,000 Gold Coins as a no-deposit welcome bonus. This is a standard offer that lets you explore the games without spending money.
First Purchase Bonus
Making your first purchase unlocks a bonus package. According to our editorial research, a $20 purchase grants you 60,000 Gold Coins plus 50 FREE Sweeps Coins.
You also get a spin on a Welcome Wheel, where you can win up to 15 additional Sweeps Coins. We found conflicting reports from third-party reviews claiming a $20 purchase gives 112,000 GC and 75 SC. We are using the editorial data as our primary source.
Daily Login & Ongoing Promotions
Zonko has "Daily offers" for returning players. One promotion is called "Instant Powerboost," which grants 25 FREE Sweeps Coins and 52,000 Gold Coins over your first 8 days of play.
The site also hosts tournaments and missions for new players, jackpot games, and a weekly scratchcard event called "Winfinite Wednesday."
Understanding Playthrough Requirements
Zonko has a playthrough requirement of 1x on bonus Sweeps Coins. This is a key term you need to understand.
A playthrough requirement (also called a wagering requirement) is the number of times you must bet the bonus amount before you can withdraw any winnings from it. Think of it like earning frequent flyer miles. You need to 'spend' a certain amount before you can 'cash in' your bonus.
A 1x requirement means you must wager the value of your bonus Sweeps Coins one time. For example, if you receive 50 bonus SC, you must place bets totaling 50 SC before any winnings from those coins become eligible for cashout. This is a very low and player-friendly requirement compared to many other casinos.
Use our Bonus Calculator to compare the real value of Zonko's 1x playthrough offer against competitors with higher requirements.
Zonko VIP & Loyalty Program
Zonko has a structured VIP Rewards program with seven tiers. As you play, you earn stars that can be exchanged for Sweeps Coins and unlock mystery gifts.
Tier Name Requirement Key Rewards Tier 1 Entry Level Basic star earning, access to missions Tier 2 Earn 100 Stars Increased star multiplier, mystery gift Tier 3 Earn 500 Stars Higher multiplier, better mystery gifts Tier 4 Earn 2,000 Stars boost, exclusive gifts Tier 5 Earn 10,000 Stars VIP-level perks, premium gifts Tier 6 Earn 50,000 Stars High-tier benefits, large SC exchanges Tier 7 Earn 250,000 Stars Top-tier status, best rewards and exchange rates The program uses a star-based progression system. You earn stars by playing games with both Gold Coins and Sweeps Coins. These stars are permanent and do not reset, allowing you to climb the tiers over time.
Our honest assessment is that the grind to the highest tiers is, as is common with VIP programs. The ability to exchange stars for Sweeps Coins provides a clear, tangible benefit, which is a positive feature. For casual players, the lower tiers offer some extra value, but the highest rewards are designed for the most dedicated players.
Zonko Games & Offerings
Zonko's game library is reported to contain approximately 525 titles. This is a solid number for a new casino, though smaller than the libraries of market leaders which often exceed 700 games.
The collection is focused primarily on slots and jackpot games. There is also a category for fishing games and scratch cards.
Our research indicates the range of table games is limited. You may find blackjack- and roulette-inspired games, but a full suite of classic table games is not present.
Software Providers & Game Categories
The specific software providers powering Zonko's games are not clearly listed in our available sources. The database lists "Slots" as a provider, which is a category, not a developer.was a false positive in some data and is not confirmed for this sweepstakes casino.
Without a verified provider list, we cannot assess the quality or fairness of the game software with the usual depth. This is a transparency gap.
The games are organized into categories for easier browsing, though some third-party reviews note that game filtering options are limited.
There is no information available about demo play functionality, average RTP (Return to Player), or progressive jackpot networks.
If you prioritize game variety and known providers, use our Comparison Tool to see how Zonko stacks up against casinos with audited game libraries from companies likeand NetEnt.
Banking: Deposits & Withdrawals
Zonko accepts several methods for purchasing coin packages. You can use Visa, Mastercard (debit cards only), American Express, and Bank Transfer (ACH). The site also supports Apple Pay and Google Pay for convenient mobile purchases.
The minimum purchase amount to trigger the first-purchase bonus is $20.
Redemptions/Withdrawals
Cashing out your Sweeps Coins winnings is a straightforward process, but it has specific thresholds.
The minimum redemption amount is 100 Sweeps Coins, which equals $100. This is a high minimum compared to many competitors that allow redemptions starting at $50 or even lower.
According to third-party sources, there may be cashout limits of $2,000 per day and $40,000 per month.
Processing times for redemptions are not instant. Standard redemptions can take up to 10 business days to complete. For Visa and Mastercard redemptions, the timeframe is reported to be 3 to 10 business days.
Method Min Max Processing Time Visa/Mastercard Redemption 100 SC ($100) Not Verified 3-10 business days Standard Redemption 100 SC ($100) Not Verified Up to 10 business days We have no information on whether Zonko charges fees for redemptions or what the KYC (Know Your Customer) verification process entails.
Check our Withdrawal Tracker for community-reported data on how long Zonko redemptions actually take once the site has more user history.
Is Zonko Legit? Safety & Trust
Evaluating the safety of a sweepstakes casino requires looking at different factors than a licensed gambling site. Sweepstakes casinos operate under US sweepstakes law, not gaming licenses, so we assess corporate transparency, legal compliance, and operational history.
Zonko is operated by Mamba Limited, a company incorporated in the Isle of Man. This corporate identity is disclosed, which is a good first step for transparency. We found an unverified claim from a third-party review that the operator is Forever Winning LLC in Delaware, USA. We are using the information from the casino's own website as the primary source.
The site has a dedicated Responsible Social Play page and publishes its Sweeps Rules and Terms of Use. These are essential documents that outline how the sweepstakes operates and your rights as a participant.
Zonko uses SSL encryption to protect data transmission on its website. This is a standard security measure for any site handling personal information.
On Trustpilot, Zonko has 7 reviews. The rating and common themes from those reviews could not be determined from our source data. As a new site, it has not yet built a substantial public reputation.
We found no record of major controversies, lawsuits, or regulatory actions against Zonko or Mamba Limited. The absence of negative history is positive, but the site's newness means its operational track record is still being established.
The site restricts play in several US states and all Canadian provinces, which shows an effort to comply with local laws. The restricted US states are California, Connecticut, Delaware, Idaho, Louisiana, Michigan, Montana, Nevada, New Jersey, New York, and Washington.
Customer Support
Customer support is a notable area of concern for Zonko based on available information.
The site does not offer live chat or telephone support at this stage. This means you cannot get instant answers to urgent questions.
The primary channel for support is email. An email address, support@zonkocasino. com. We have no data on typical email response times or the quality of the support team's answers.
We could not locate a help center or FAQ section on the site. A FAQ is a basic tool that helps players solve common problems without contacting support.
The lack of multiple, responsive support channels is a weakness, especially for players who may have questions about redemptions or account verification. Established competitors typically offer 24/7 live chat.
Mobile Experience
We have no specific data on Zonko's mobile experience. Our research brief does not confirm whether Zonko has dedicated iOS or Android apps, or what their App Store or Google Play ratings might be.
The site supports Apple Pay and Google Pay, which suggests it is optimized for mobile browsers. However, we cannot assess mobile browser performance, game count parity with the desktop site, or the overall user experience on smartphones and tablets.
Until more information is available, players should assume they can access the site via a mobile web browser, but the experience may vary.
Where Is Zonko Available? Legal Status
Zonko is a sweepstakes casino, which is a legally distinct model from online gambling. It is available in most US states but has specific geographic restrictions.
You cannot play Zonko if you are physically located in the following US states:
California
Connecticut
Delaware
Idaho
Louisiana
Michigan
Montana
Nevada
New Jersey
New York
Washington
Zonko is not available in any Canadian province or territory. This includes Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland and Labrador, Northwest Territories, Nova Scotia, Nunavut, Ontario, Prince Edward Island, Quebec, Saskatchewan, and Yukon.
The age requirement to play at Zonko is not specified in our sources. For sweepstakes casinos, the standard minimum age is usually 18, but some jurisdictions or site-specific rules may require players to be 21. You must check the site's Terms of Use for the official age policy.
Who Is Zonko Best For?
Based on our analysis, Zonko is best for specific player profiles and may not be the right fit for others.
Best for you if: You are a new sweepstakes player looking for a simple bonus with a low 1x playthrough requirement. You are also a good fit if you prefer a smaller, more curated game library and do not mind a higher minimum cashout threshold.
Also best for you if: You value corporate transparency and want to play at a site that clearly discloses its operating company (Mamba Limited).
Look elsewhere if: You need instant customer support. Without live chat, Zonko is not suitable for players who require quick answers. Try Stake.us or Pulsz instead, as they offer 24/7 live chat.
Also look elsewhere if: You want to cash out small wins frequently. The 100 SC ($100) minimum redemption is high. If you prefer lower thresholds, consider Chumba Casino, which has a $50 minimum redemption.
How to Sign Up at Zonko
Creating an account at Zonko is a standard process for sweepstakes casinos. Follow these steps to get started.
Visit the Zonko website. Ensure you are in a state where the site is legally available.
Click the "Sign Up" or "Register" button, typically found in the top corner of the homepage.
Fill out the registration form. You will need to provide a valid email address, create a password, and enter your personal details including your full name and date of birth.
Agree to the site's Terms of Use and Sweeps Rules. It is important to read these documents.
Verify your email address by clicking the confirmation link sent to the email you provided.
Once verified, you can log in. Your account will be credited with the 3,000 Gold Coin welcome bonus automatically.
The entire process should take only a few minutes. You will need to complete account verification (KYC) before making your first redemption, which usually involves submitting a photo ID and proof of address.
Final Verdict
Zonko presents a mixed profile typical of a newer sweepstakes casino. It offers a compelling 1x bonus playthrough and a respectable 525-game library, but it is hampered by a $100 minimum cashout and a lack of immediate customer support channels.
The operator, Mamba Limited, has incorporated in a credible jurisdiction like the Isle of Man, which is a positive signal for corporate governance. The site's adherence to sweepstakes law is evident in its published rules and its blocking of 11 restricted US states and all of Canada. However, its 2026 launch date means it lacks the multi-year track record of trust that sites like Chumba Casino have built.
For players who prioritize a simple bonus structure and do not require frequent small withdrawals, Zonko is a viable, if unproven, option. Players who need solid support, a wider game selection from known providers, or faster cashouts should consider more established alternatives.
Before depositing, I recommend reading Zonko's Sweeps Rules in full to understand the Alternative Method of Entry (AMOE) and all contest terms. This is the best way to verify its operational legitimacy.
Our Verdict
Zonko earns an expert score of 4.18 out of 5. As a new entrant in the sweepstakes space, it demonstrates legitimate foundations but shows the limitations typical of a young platform.
The casino's strongest point is its player-friendly bonus structure. The 1x playthrough requirement on bonus Sweeps Coins is among the lowest you will find. This makes bonus funds easier to convert to cashable winnings compared to sites with 5x or 10x requirements. The welcome bonus and first-purchase offer provide a standard entry point for new players.
However, Zonko has clear areas for improvement. The absence of live chat support is a drawback, especially when competitors like Stake.us and WOW Vegas offer 24/7 chat. The 100 SC minimum redemption is double the threshold of many rivals, locking out players who accumulate smaller wins. The game library, while decent, lacks the breadth and provider diversity of established leaders like Pulsz, which has over 700 slots from major studios.
Zonko is best for patient, casual players who prioritize simple bonus terms over instant support and low cashout limits. It is a viable option if you are comfortable with email-only support and do not mind waiting up to 10 days for a redemption. The transparent corporate identity of Mamba Limited is a positive trust signal.
If you are a high-volume player who needs responsive support, look to Stake.us. If you want a massive game selection, Pulsz is the better choice. If you need to cash out amounts under $100, Chumba Casino is a more suitable platform. Zonko occupies a middle ground as a straightforward, new sweepstakes casino that gets the core model right but lacks the polished features of its more mature competitors.

What is the minimum redemption at Zonko?
The minimum redemption amount at Zonko is 100 Sweeps Coins. Since 1 Sweeps Coin equals $1, this means you must have at least $100 in winnings from SC play before you can request a cashout. This is higher than many competing sweepstakes casinos.
