What we don't like

• The welcome bonus wagering requirement is considered above industry standard at 40x the bonus + deposit

• Only self-exclusion and cooling off periods available as part of the site's suite of responsible gambling options

CleanWins Casino Overview

Overview of Available Bonuses at CleanWins Casino

CleanWins offers a comprehensive suite of bonuses mostly targeting online slot players; however, there is a live casino cashback. The welcome bonus, reloads, and daily free spins Wheel of Fortune offers exclude bets on non-slot games. Two cashback offers cover slots and live dealer gaming, and you’ll also come across a ‘Happy Hour’ spins session, aimed at helping players climb the site’s VIP ladder.

Step-by-step Registration & Bonus Activation Guide

1. Click Register in the top-right corner and complete the sign-up form with accurate personal details.
2. Once you have an account, make your first deposit of at least €20 and enter the bonus code WELCOME2000 in the cashier.

• 💡Expert Tip: Make sure all the information provided when you sign up matches the documents you typically use to pass KYC checks.

Welcome Bonus - 200% up to €2,000 + 200 free spins (+extra 50 FS)

The CleanWins welcome bonus is worth claiming if you play online slots. 100% of your bets contribute towards the wagering requirement. The offer’s percentage match is also perfect if you’re looking to get started with a high bonus balance, thanks to a 200% match, which doubles the amount most competitors offer, plus there’s an opportunity to add an additional 50 free spins to the headline bonus offer.

• First Deposit: 200% deposit match up to €2,000 + 200 free spins worth €20 (€0.10 per spin) on Big Bass Bonanza - Bonus code (WELCOME2000)
• Extra 50 Free Spins: You’ll earn another 50 free spins on top of the 200 advertised in the headline welcome bonus if you deposit via Open Banking/Instant Bank Transfer.

We claimed the welcome package using the promo code, but as per most bonuses, our bonus funds were not immediately available. The rules are that it only becomes active if you lose your first deposit within the first 10 days of your first deposit. As we hit a winning streak during our first 2 weeks, the bonus expired.

Main Bonus Rules

• 🤔 Quick Summary: Many of the CleanWins welcome bonus rules are industry-standard, such as the €20 minimum deposit, €5 max bet, and real money bets do not move the wagering requirement progress bar. However, given the high wagering requirement, we feel the 10-day validity period is short. Bearing all this in mind, our advice is to use this offer if your strategy is to have a bonus balance in place so you can play for longer if you happen to lose your real money balance before the validity period expires.

Reload Bonus Offers, Cashback Bonus and Other Promotions

Slot players can claim free spins daily with their first deposit of the day. It’s not exactly free spins every day, because you have to deposit, but it’s nice to know that when you are planning your next deposit, the option is there. Also, if you have a bad week playing slots or live dealer games, some of your losses are returned with 0x wagering.

• Daily Wheel Of Fortune: Every day on your first deposit, you’ll qualify for the chance to win up to 300 spins with one spin on the CleanWins ‘Wheel Of Fortune’, which comes with three levels.

• Level 1 (€20 - €99.99 deposit): Up to 70 free spins or up to 140 spins if your spin lands on the ‘Reward x2’ segment
• Level 2 (€100 - €299.99 deposit): Up to 100 free spins or up to 200 spins if your spin lands on the ‘Reward x2’ segment
• Level 3 (€300+ deposit): Up to 150 free spins or up to 300 spins if your spin lands on the ‘Reward x2’ segment
• Weekly Slots Cashback (0x wagering): The slot cashback returns 10% of your losses from the previous week. If you lose €50 up to €10,000 playing slots, you’ll qualify for the €5 minimum up to the €1,000 maximum cashback, paid in cash with no wagering requirement.

• Live Casino Cashback (0x wagering): As a live casino player, you’ll have 5% of your net losses returned for any losses from the week before. The minimum amount returned is €5, and the maximum amount is €200. As with the slots cashback, there is no wagering requirement.

• Weekly Reload: Deposit €20 with the bonus code WEEKLY250 for a 50% deposit match up to €250 available once a week, and the wagering requirement is only 25x deposit + bonus wagering requirement.

• Refer-a-Friend (0x wagering): Send your referral link, and if your friend signs up and deposits €20 or more, you’ll earn €5 cash, and your friend will receive 10 wager-free spins worth €0.10 per spin.

CleanWins VIP and Loyalty Program

If you play regularly, climbing the VIP rewards program is worthwhile. There are 5 levels, and if you reach Sapphire, you’ll earn additional online slots cashback percentage increases.

• Level 1 (Quartz)
• Level 2 (Emerald)
• Level 3 (Sapphire) 5% cashback on your net losses for the week
• Level 4 (Ruby) 10% cashback on your net losses for the week
• Level 4 (Diamond) 15% cashback on your net losses for the week

Advancing through the loyalty program enhances your casino experience with extras such as priority support and payment processing (for faster withdrawals, a dedicated VIP manager, birthday benefits and rising weekly cashback of 5%, 10% and 15% at Sapphire, Ruby and Diamond, respectively.

The Game Providers and iGaming Lobbies at CleanWins Casino

CleanWins' main focus is on video slots and live casino players, which are the t two main lobbies you’ll have available on the menu and the homepage. Naturally, the slot lobby features the largest number of games and software providers, as there’s always going to be far more available compared to live dealer games. Software providers with the largest game portfolios include Play’n GO, Pragmatic Play, Betsoft and Blueprint, while live tables are supplied by Lucky Streak and Vivo Gaming rather than a market leader such as Evolution.

Slot Machines, Jackpot Slots and Instant Games

At the top of the slot menu, many of the games listed we recognise not just because they are well-known, but also because they have won industry awards. Rise of Olympus, Big Bass Splash and Gonzo’s Quest Megaways have all won ‘Slot of the Year’ awards at different iGaming awards events. As for categories available, the slot sections mostly aim at high-volatility gameplay via ‘Megaways’, ‘Bonus Buy’ and ‘Book of Games’. Although you will find some of these games also offer medium volatility gameplay.

If you’re looking to spin the reels with the chance to win a progressive jackpot while earning multipliers from your usual bonus rounds and slot features, the jackpot category features progressive and fixed jackpot slots from Fazi, G Games and Gmzix.

The slots lobby also gave us access to a ‘Table games’ lobby, which is an odd place to put them. Nonetheless, if you are looking to play virtual baccarat, blackjack, poker and roulette with no time limits between each round, then there are 48 games listed in this section.

• 🤓 We particularly liked this game: Big Bass Bonanza stands out as the game used for the welcome bonus free spins, and during the time we played, the slot was almost always one of the first in the list. We like the mid-to-high volatility fishing-themed slot.

Live Casino as well as Table and Card Games

The CleanWins live casino focuses mostly on Blackjack and Roulette, as these are the two main lobbies available. If you’re looking for baccarat, dice games, or live poker, these are mixed into the ‘All Live’ section. Las Vegas Roulette, Portomaso (land-based roulette), and several auto-roulette wheels, alongside live blackjack (including Blackjack Prestige) and baccarat tables, are featured.

As Lucky Streak and Vivo Gaming are the only two studios, there are no game shows, and there’s not much in the way of high-stakes games, VIP rooms or high-roller limits displayed.

• 🤓 Top live casino game for beginners: For newcomers, one of the standard auto-roulette wheels makes for an easy starting point. There’s no pressure from a live dealer and betting is simple, making these tables a great way to prepare for the roulette tables featuring a live dealer croupier.

Deposits and Withdrawals

The cashier is neatly laid out and accessible from any page on the site, whether you connect via desktop or mobile. There’s also a good range of payment methods, including bank cards, e-wallets and bank transfer for euro deposits, plus you can deposit using a variety of cryptos.

Deposits

• Cards (Visa, Mastercard)
• Bank transfer (Open Banking, instant bank payment)
• Cryptocurrency (Bitcoin, USDT ERC20, USDT TRC20, USDC ERC20)

The minimum deposit is €20. The terms state that CleanWins absorbs most deposit transaction fees, so deposits are generally free, though your own bank may add charges and some methods apply currency-conversion fees.

Withdrawal Duration, Limits, Verification and KYC

• Cards (Visa, Mastercard)
• Bank transfer (Open Banking, instant bank payment)
• Cryptocurrency (Bitcoin, USDT ERC20, USDT TRC20, USDC ERC20)

The minimum withdrawal is €20, and your cashout will be returned to the method used to deposit. A 1x rollover of deposits is required before CleanWins will approve a withdrawal, or there may be a charge up to an 8% fee. That same fee can apply to multiple withdrawals within 30 days. As for cashout limits, there are €5,000 per seven days and €15,000 per 30-day maximum.

All players must pass a KYC check before making their first withdrawal. If you’ve already submitted a cashout request, you’ll have 72 hours to supply documents. In some cases, the site may require that you provide KYC information before you begin betting.

• 💡Expert Tip: Send your passport, driving licence or national identity card, recent utility bill, a selfie, and proof of ownership of your payment method by email after you sign up. This way you can avoid problems later down the line when you want to process a withdrawal.

Website Design, Usability and Mobile Use

The site has a clean, dark-green theme with a simple top menu and a left-hand slide-out for game categories. We found that navigation is mostly logical, with the lobby split into slots and live casino and clear tabs for Top, New, Megaways, Bonus Buy, Jackpots and Table Games. The only point that did throw us was finding the ‘Table Games’ section containing virtual tables in the slot section, as mentioned in the CleanWins slot review section above.

As for performance, pages load quickly across mobile and desktop, which we tested using web browsers. Also, whether using a large PC monitor, smaller laptop screen or on mobile devices, the layout is responsive and scales to the browser without delay.

Casino App

We did not find a downloadable native app for iOS or Android. CleanWins is played through your device’s mobile browser, which works smoothly on phones and tablets.

Experience with Customer Support at CleanWins Online Casino

Support is offered mainly through live chat and email, with a Zendesk-powered chat widget on every page; behind it is a support team that offers 24/7 assistance. If you’re looking for fast self-help answers, unfortunately, there’s no FAQ section.

How to Contact CleanWins Customer Support

• (Live Chat): Open 24/7 for customer support in real time
• (Email): Send emails to [email protected]
• (Complaints): The T&Cs include a Complaints clause (section 21); grievances go to customer support and must be lodged within three days of a disputed wager.
• (ADR): If support cannot resolve a dispute, the terms escalate it to management and, ultimately, to arbitration; no independent ADR provider is named.
• ❓Contact with live chat: Can we claim bonuses using crypto deposits instead of euros?

Elia was the support agent that rep[lied, who connected within about a minute and confirmed that as long as we deposit the euro equivalent minimum, then yes, crypto can be used to claim any of the bonuses on the site. The reply was polite and accurate, though it arrived in stages with short waits. Overall, we are happy that the live chat proved helpful and the support agent knowledgeable.

Comparing CleanWins Casino with iGaming Competitors

We compared two online casinos, offering different-sized welcome bonus options, wagering requirements and payment terms.

OlympusBet Casino

100% up to €500 + 25 Free Spins

Play

4.1 / 5.0

EmirBet Casino

Play

3.8 / 5.0

CleanWins offers the largest welcome bonus at €3,000, while they all offer a 40x bonus rollover; CleanWins has the biggest value for the welcome bonus. Another point that stands out is that CleanWins does not offer sports betting.

Rounding Up Our CleanWins Casino Experience

CleanWins is certainly worth considering if you are a regular player looking for daily free spins bonuses, or at least free spins with every new deposit, and cashback on losing weeks without grinding through wagering requirements. The casino has a large enough game selection from software providers that have built a solid reputation in the iGaming industry. That said, it’s not the largest provider list we’ve seen, so there’s room to grow.

With regular bonuses mostly offering 0x wagering bonuses, and a reload with 25x (d+b) wagering, the casino’s welcome bonus wagering requirement is a bit of a stumbling point. The headline bonus looks great with its 200% match, which is double most rival casino sites, but the 40x (d+b) wagering requirement makes it more for show than a realistic chance of converting it into real money.

All in all, if you are fine with using the welcome offer as a backup to your real money balance while you get acquainted with CleanWins, and you’re more focused on the 0x wagering and weekly reload with a lower bonus rollover, head over to the casino from this review to find out more.
