Cosmoswin Casino Welcome Bonus
The Cosmoswin Casino welcome bonus, or the Supernova bonus rewards new players with up to $20000 and 100 free spins. The bonus amount you get is 100% of the amount you deposit, and the minimum deposit requirement is $100. Aside from this, players should wager the bonus and the deposit 40 times within 14 days, with a minimum stake of $5.
One of the things we most like about this bonus is that it can be used in many game categories, such as slots, table games, live casino, and others.
Cosmoswin Casino Welcome Package
Cosmoswin’s “Orion’s Belt” welcome package also rewards with $20,000, and can be claimed with the first 3 bonus purchases, as follows:
- 100% up to $5,000 on your first purchase
- 75% up to $5,000 on your second purchase
- 125% up to $10,000 on your third purchase
The Cosmoswin welcome bonus package and the deposit should be wagered 40 times within 14 days, and you should have at least $20 on your casino balance. The bonus can also be used on many categories of games, excluding those from Mascot Gaming.
Cosmoswin Casino Cashback
Cosmoswin Casino offers cashback based on your losses, in the following order:
- 10% cashback for losses of $50 and more
- 15% cashback for losses of $200 and more
- 20% cashback for losses of $1,000 and more.
Players can receive a minimum cashback of $5 and a maximum of $10,000 daily. However, to be eligible to receive cashback, you should make at least 20 bets, with no wagering requirements applied. Also, the cashback applies to all the available games, which is a huge advantage for players in this casino.
Cosmoswin Free Spins
Cosmoswin players can also grab 50 free spins weekly, on the Red Dragon vs Blue Dragon slot by Redrake. However, Cosmoswin free spins should also be wagered 40 times within 7 days, and you should have a minimum of $50 on your balance to use the offer. A single free spin has a value of $0.20, and the maximum stake that counts is $5.
Cosmoswin Reload Bonus
Players at Cosmoswin can get a reload bonus of 50% up to $100 once a week. As with the other Cosmoswin promotions, the reload bonus has wagering requirements of 40x within 7 days and requires $20 on your balance.
The weekly reload bonus applies to all the game categories, except for games by the provider Mascot Gaming.
Cosmoswin Bonus Shop
One of the most unique features of Cosmoswin Casino is the Cosmoswin Bonus Shop. The bonus shop allows players to buy a customised Cosmoswin no deposit bonus, even with money from winnings. The bonuses you can buy range from cashback, free spins, and scratch cards to different deposit packages, depending on the time and availability.
Cosmoswin Bonus Wagering Requirements – How Fair are They?
All the Cosmoswin bonuses have wagering requirements of 40x, which apply to the deposit and bonus amount. We consider this very high and unfair, as you must play through your deposit and bonus amount 40 times before you can withdraw any winnings.
Except for the very high Cosmoswin wagering requirements, the maximum stake that counts towards these requirements is $5, which complicates the situation further. For cashback bonuses, there are no wagering requirements, but the maximum reward is capped at $10000, which can be quite limiting for high-rollers.
Cosmoswin Casino Games
Cosmoswin offers a decent number of around 2500 games, including slot games, table games, and live casino. Even though the portfolio is not very versatile, you can still enjoy popular titles by providers such as Pragmatic Play, Booming Games, Betsoft, Evolution, and others. In this section, we cover each of the gaming categories in detail, so keep reading.

Cosmoswin Slots
The Cosmoswin casino slots category offers more than 2000 slots by over 30 popular iGaming brands. Some of the names you will see here are Quickspin, 1×2 Gaming, Spinomenal, Betsoft, and others.
Even though the desktop version is not well optimised, gamblers can play their favourite slots on the mobile version hassle free. To be more specific, you can access the “Slots” category directly from the home page, and filter slots by their provider to easily find your favourite title. Some popular titles include Big Bass Bonanza, Sun of Egypt 3 ,Wilds of Fortune, and Electric Sevens.
Cosmoswin Table Games
Cosmoswin Casino also has something for gamblers who enjoy table games. On this platform, you can find blackjack, poker, baccarat, and roulette titles from providers like Betsoft, Evolution, Evoplay, and Mascot Gaming. Some popular variations are Blackjack Vegas Strip, Oasis Poker, French Roulette, and American Baccarat Zero Commission.
Cosmoswin Live Casino
The Cosmoswin live casino section gives players the opportunity to play with human dealers and compete against other players without having to visit a land-based casino. In this category, you can find variations of roulette, blackjack, poker, and baccarat, as well as other popular games like Craps, Dream Catcher, and Crazy Time.
Other Games
Like mentioned above, gamblers can enjoy a vast collection of games at Cosmoswin Casino. Except for slots and table games, the casino also offers TV show games like Mega Wheel, Monopoly, Craps, Crazy Time, Sweet Bonanza Candiland, and many other titles. Under the “Providers” section, you will encounter names such as Pragmatic Play, and Evolution.
Cosmoswin Casino Payment Methods
We already mentioned that Cosmoswin is a crypto casino, and they only accept payments in cryptocurrencies. The platform supports cryptocurrencies such as Bitcoin, Ethereum, Dogecoin, Litecoin, DAI, Bitcoin Cash, and others. What we love about this platform is that there are no minimum or maximum Cosmoswin deposits and withdrawals. Deposits are instant, and withdrawals may take up to 2 hours if the KYC verification is passed.
However, what we didn’t like is that even though it’s a crypto casino, the base currency on the site is USD. This may confuse some players that they can play in other currencies, aside from cryptocurrencies.
Also, even though crypto players may be happy with the payment section, this platform is not suitable for players that prefer other payment methods. So, if you’re more interested in Paypal Casinos, Google Pay Casinos, or platforms that offer versatile payment methods, we suggest checking out the recommendations on our site.
Cosmoswin withdrawal procedure – How hassle-free is it?
Cosmoswin is among casinos that offer very fast withdrawals – up to 1 to 2 hours in cryptocurrencies. However, during our review, we came across both positive and negative comments about the platform’s withdrawal process.
Namely, some players claim that the casino paid out their winnings within the withdrawal period of 2 hours, while others complained about delays. On the other side, the comments about the customer support agents were rather positive, claiming that they’re very friendly and eager to help gamblers who have problems with withdrawals.
