Launched in 2020, Winz.io is a hybrid casino that supports both cryptocurrency and fiat payments. It is operated by Dama N.V. (company registration no. 152125, Curaçao) and uses Friolion Limited in Cyprus for certain payment processing. Thanks to Dama’s size, Winz.io has access to a wide range of game providers, secure payments and established infrastructure.

Winz.io is licensed by the Curaçao Gaming Control Board (OGL/2023/174/0082), replacing its former Antillephone N.V. license. Curaçao licensing supports crypto transactions but offers lower consumer protection than regulators like the UKGC or MGA.

Pros & Cons

Why Choose Winz.io?

Winz.io offers the flexibility of managing both crypto and fiat currencies within a single account. Its ‘wager-free’ bonuses, such as the Wheel of Winz and daily cashback, allow players to keep their winnings without having to meet the usual 30–50x wagering requirements.

The deposit turnover rules are low and straightforward. The casino features thousands of slots, hundreds of live dealer tables and exclusive titles such as ‘Winz to the Moon’.

The interface is fast and easy to navigate, with mobile performance matching that of the desktop site.

Casino Bonuses and Promotions

Winz.io offers multiple interesting promotions. All winnings from welcome offers, cashback, and tournaments are paid in real money with no hidden rollover. This makes the platform stand out compared to most competitors.

Welcome Bonus Offer

The best currently available Winz.io promo code is VIPGRINDERS. New players who use it when they sign up can unlock a wager-free welcome package worth up to €10,000 (or 100 mBTC). The bonus is part of the Wheel of Winz, which guarantees prizes on every spin.

To get any welcome offer, you have to deposit at least €25 (or the equivalent in crypto). You can make eligible deposits in 12+ cryptocurrencies (BTC, ETH, USDT, SOL, etc.) or in fiat directly on the platform.

Wheel of Winz

Beyond the welcome spin, Winz.io also hosts weekly Wheel of Winz events where players can win up to €30,000 across three periods.

Players can deposit €50 or more (Bronze), €100 or more (Silver), or €200 or more (Gold) with the relevant bonus code to spin the wheel and win prizes of up to €10,000 cash.

VIP & Loyalty Program

Winz.io has a dual rewards system for its regular players. The first is the WinzUp Program, a loyalty program with four tiers: Bronze, Silver, Gold, and Diamond.

As you progress through the levels, you unlock more benefits. These include daily rakeback between 5% and 10%, weekly cashback of up to 15%, and level-up bonuses starting from 2% per milestone.

All of these rewards are paid as real cash with no wagering requirements, making it one of the most player-friendly loyalty programs online.

Sports Betting Markets

Winz.io offers betting on over 38 different sports, including both popular and niche options. Core sports markets feature soccer, basketball (NBA, WNBA), tennis (including major tournaments), cricket (like the IPL and ICC T20 World Cup), ice hockey (NHL, AHL, SHL), rugby, volleyball, and boxing, along with lesser-seen markets such as lacrosse, chess, floorball, water polo, and political or novelty events (e.g., Oscars, weather).

Leagues and Tournaments Covered

Winz.io offers many betting options, including match winner, totals (over/under), handicaps (spread betting), outright winners, correct scores, multi-bets (accumulators/combo bets), and player or half-time bets for many sports.

It offers a reliable sportsbook experience, but it doesn’t have Bet Builder features or a wide range of advanced prop markets. This makes it less ideal for bettors who want highly specialized or customizable bets.

The platform includes basic statistics, and for eSports, they provide live streams via Twitch.

Odds at Winz.io are competitive and stay the same across most betting markets. However, they are shown only in decimal format, with no option to switch to American or fractional formats as of 2025.

Sports Betting Odds

Winz.io markets its sportsbook as offering exceptional odds, but independent analysis reveals a more nuanced picture.

The bookmaker’s margin on major football moneyline markets can reach almost 10%, which is much higher than the industry average of 4-5% for popular, high-liquidity events. Also, totals (over/under) markets often have an extra 1% margin compared to standard rates.

Overall, Winz.io’s odds are good enough for casual bettors but not as good for those who want the best value or want to maximize their profit. Its margin is about 6%, which is average or slightly below some of the best sportsbooks.

Casino Games

Winz.io has a large collection of casino games with over 7,500 options, making it easy for players to find something they like.

The collection includes many categories:

Slots

The largest part of the library has everything from classic 3-reel slots to modern Megaways and Cluster Pays games. Popular titles include Book of Dead, Wolf Gold, Starburst, and a special “Buy Bonus” section for instant access to bonus rounds.

There’s a wide variety of games, including several types of blackjack, roulette, baccarat, and poker, as well as specialty games like Sic Bo, Keno, and bingo. The casino also has popular games like Aviator and Plinko.

Jackpot Slots

Progressive jackpots like Mega Glam Life and Aztec Fire 2 offer growing prize pools that are shared across the whole network.

Exclusive Games

Winz.io has unique titles made just for them by partners like BGaming and Red Tiger. These include Winz to the Moon, Winz.io Bonanza, and Moonwalkers. Some of the games may have a slightly higher chance of losing.

Popular live game shows like Crazy Time, Monopoly Live, and Crazy Coin Flip are also featured. Professional dealers interact with players via live chat, creating an immersive, social atmosphere similar to that of land-based casinos.

Winz.io works with over 60 top game providers. This means that there are always new games to play, and you can find popular and new games. Key providers and notable games include:

User Experience

Winz.io is easy to use, works well on any device, and has a quick registration process.

The site has a simple, easy-to-use design with a menu that makes it easy to access Slots, Live Casino, Sports, and Promotions. A search bar allows you to quickly find a game. Most RNG games let you try them for free.

There isn’t a mobile app made just for that, but the website works well on all modern devices. It supports all games, including live dealer streams.

Registration is fast and easy. You just need an email address, a password, and you can choose your preferred currency.

KYC verification is delayed until withdrawals reach €2,000 (or 7 BTC) or there is suspicion of fraud.

When triggered, KYC requires uploading a government-issued photo ID, proof of address (like a utility bill or bank statement within 3-6 months), and proof of deposit ownership. Verification is usually finished within 24 hours.

Payment Methods

Winz.io offers a flexible payment system that supports many traditional currencies and cryptocurrencies.

Winz.io supports over a dozen of the most popular cryptocurrencies, including Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC), Bitcoin Cash (BCH), Dogecoin (DOGE), Tether (USDT), Ripple (XRP), Binance Coin (BNB), Cardano (ADA), Tron (TRX), USD Coin (USDC), and Solana (SOL).

You can also use many different types of fiat currencies, including popular ones like EUR, USD, AUD, CAD, NZD, and others such as RUB, NOK, JPY, BRL, INR, ZAR, KZT, and CHF.

The table below shows the main details for the different ways to pay at Winz.io. It compares the limits for fiat (dollar) and cryptocurrency (like Bitcoin) options:

Customer Support

Winz.io offers 24/7 live chat as the primary support channel, with email (support@winz.io, info@winz.io), a contact form, and a detailed FAQ for other queries.

Live chat is praised for fast, helpful responses and efficient handling of routine issues. However, there are serious complaints about how high-value disputes are managed.

Some users report account locks and fund confiscations over unproven fraud claims, with poor communication during dispute resolution.

Overall, support is reliable for basic issues but has notable weaknesses in handling complex or high-stakes disputes.

Players are responsible for complying with gambling laws in their jurisdiction.

Game fairness is ensured through licensed providers and Provably Fair games that allow result verification.
