Payment Methods
As a crypto casino, Cosmoswin exclusively accepts payments in cryptocurrencies. Supported cryptocurrencies include Bitcoin, Ethereum, Dogecoin, Litecoin, DAI, Bitcoin Cash, and others. One appealing aspect of this platform is that there are no minimum or maximum deposit and withdrawal limits. Deposits are processed instantly, while withdrawals may take up to 2 hours, assuming the KYC verification is successfully completed.
However, it is worth noting that despite being a crypto casino, the base currency on the site is USD. This may cause confusion for players who assume they can play with currencies other than cryptocurrencies.
Furthermore, while crypto enthusiasts will appreciate the payment options, Cosmoswin may not be suitable for players seeking alternative payment methods. If you prefer platforms offering versatile payment methods like PayPal Casinos or Google Pay Casinos, we recommend exploring the recommendations on our site.
Mobile
In today's smartphone-dominated era, the majority of players prefer accessing their favorite casino games through mobile devices. While Cosmoswin does not currently offer a dedicated casino app, their mobile website is well-optimized for an enjoyable gambling experience.
Upon visiting the homepage, the Cosmoswin login and register buttons are conveniently located in the header, remaining easily accessible regardless of scrolling. The game categories are also readily available and can be accessed effortlessly from the homepage. The bottom section of the webpage features buttons for the main menu, wallet, promotions and bonus shop, a search function for finding favorite titles, and live chat support.
Customer Support
Cosmoswin provides customer support 24/7 via live chat and a contact form. During our casino review, we encountered friendly and professional support agents who were eager to assist and resolve any issues.
However, it is worth mentioning that some players have reported less responsive support during nighttime hours. Additionally, customer support is currently available only in English and Japanese. This limitation may be seen as a disadvantage considering that Cosmoswin is an international platform catering to players from various regions.

Security and Licenses
Cosmoswin is owned by Final Enterprises N.V. and operates under the Master Curacao license number 1668/JAZ. It is important to note that a master license means that the Curacao government does not directly regulate the casino but delegates the regulation to independent entities.
It is unfortunate that there have been scandals and negative experiences associated with casinos operating under master licenses, including instances of licensing pirated software and scamming players. Therefore, it is crucial to exercise caution when engaging with such casinos and conduct thorough research before making any deposits on any platform.
The desktop version of the website is poorly optimized, challenging to navigate, and plagued with various bugs that need addressing. Additionally, the high wagering requirements of 40x can be restrictive and limiting for some players. Lastly, incorporating a wider range of payment methods would be beneficial in welcoming more players to the platform.

Scam Casino, Avoid I decided to self-exclude myself from the website due to lack of success. Customer service commended me for that but is refusing to send the $25 I had left in the account. Update: They keep saying my request is in process, hoping I give up. This is a clown show, please avoid this scam.
Possibly the worst online slot site I've ever tried. After going through the ridiculous amount of verification steps, I played a slot called 9 pots of gold. To start with, on 20p spins, I won around £70, which was great. Since I won that amount, I decided to use their win booster feature, which increased the stake to 40p with enhanced chances of winning. From then on, I lost £110 with very few wins in between. I only hit the bonus twice, one winning £2 and the other £6, off 10+ free spins with enhanced bonus odds at a 40p stake. Prior to this, on 20p without the win booster, I won over £15 twice on the bonus feature. I have never played a slot as rigged as this one. They shouldn't advertise a win booster feature that doubles the stake and actually decreases the odds of winning. I wouldn't waste your time and energy with this company.
Processing Withdrawals Slow. Online casinos frequently con players by delaying withdrawals and requesting excessive amounts of documentation for verification. Every online casino will need verification documents for KYC purposes, however con artists frequently reject the provided documents or drag out the procedure until the player gives up.
Aside fr om the deposit, there are no restrictions. Please add more limits that may be set through support to keep the player safe, such as a time lim it, loss limit, and cool down period.
They have a few decent slots, but I'm missing a few. I want withdrawals of more than 200 euros could be sent via e-wallets. However, with strong customer service, they will attempt to find a solution for you.
