Sirwin Casino Bonuses for 2025
Sirwin crypto casino offers a range of bonuses for both new and existing players. While there isn’t a Sirwin casino no deposit bonus available at the moment, there are several other hot promos you can take advantage of. We’ll break down each offer in detail below.
100% Welcome Bonus
The Sirwin sign up bonus gives new players a 100% match up to $1,000 on their first deposit. This means if you deposit at least $5, Sirwin casino will double it, giving you extra funds to explore the platform’s 7,000+ games, including slots and live casino options.
You don’t need a Sirwin casino bonus code to claim this offer. However, you must select the bonus option on the website right after your deposit is credited to your balance. This has to be done before you start playing any games. If you skip this step or play before activating the bonus, you’ll miss out.
Keep in mind the following key terms:
- Wagering requirements: The bonus amount must be wagered 50x, and the deposited amount at least once before requesting a withdrawal
- Live Casino wagering: applies to roulette only, with specific restrictions on odds and bet spreads (e.g., no bets at odds of 1 to 2 or 1 to 3, and a max of 12 numbers covered)
- Maximum withdrawal: 30x your deposit when playing with bonus funds
- High-risk players: flagged by Sirwin’s Risk department may be subject to up to 10x deposit wagering before withdrawals are approved
Overall, the 100% Sirwin sign up bonus is a solid way to kickstart your experience at this top online casino. Since there’s no Sirwin promo code to claim this bonus, just select the bonus before you start playing any games. Otherwise, you’ll lose the opportunity to claim the welcome offer.
15% Casino Cashback
Sirwin Casino offers a cashback bonus that gives you back up to 15% of your losses on both live casino and online slots. This is a great option if you’re playing regularly. There’s no Sirwin coupon code needed to claim this offer.
If your balance drops below $1, you can request cashback within 48 hours of your loss. Once approved, the cashback is credited to your account, and you can use it to play any Sirwin crypto games or withdraw it directly. There are no wagering requirements on the cashback itself.
The cashback percentage depends on how much you’ve lost over a certain period. Losses between $1 and $99,999 qualify for a 10% cashback, while losses over $100,000 earn you 15%.
This bonus can’t be combined with other offers; only one cashback request is allowed every 24 hours. It’s quite a good deal if you want to minimize risk while enjoying Sirwin crypto games.
Key Terms:
- No wagering requirements on cashback. Funds are withdrawable or can be used for betting right away
- Cashback applies to losses on live casino and Sirwin crypto slots only
- Balance must be under $1 to qualify, and the cashback request must be made within 48 hours of your loss
- Cashback amounts are capped at 40 times the bonus received when withdrawing
- Members whose withdrawals exceed deposits in the last 24 hours are not eligible
5% Deposit Bonus
Sirwin casino offers a 5% deposit bonus available through all payment methods. This bonus is a simple way to boost your balance with minimal effort. To claim it, you need to make a minimum deposit of $5. Once your deposit is credited to your account, select the bonus option on the website before playing any games. No Sirwin bonus codes are required for this offer.
This bonus works across slot games, live casino, and sports betting. Wagering requirements differ depending on where you play. Slot players have the easiest terms, while live casino and Sirwin crypto betting options come with higher requirements. It’s an added incentive for regular players looking for consistent rewards at Sirwin casino.
One important point to keep in mind is that members whose withdrawals have exceeded their deposits in the last 24 hours aren’t eligible for this bonus. So, if you’ve recently cashed out more than you’ve put in, you’ll need to wait before claiming the offer.
Key Terms:
- Sirwin Crypto Slots: No wagering on the bonus. Deposit must be wagered 1x
- Live Casino: Wager deposit 1x and bonus 10x. Some bets are excluded
- Sports Betting: Wager deposit 1x (minimum odds 1.50) and bonus 10x (minimum odds 1.90 for singles; 1.50 per leg for combos)

Sirwin Sportsbook Bonuses for 2025
While the selection of sportsbook bonuses is smaller compared to the casino offers, Sirwin crypto sportsbook still delivers a solid deal for sports bettors. Cashback on betting losses is a rare find at offshore casinos, making this offer stand out if you’re into regular sports wagering.
5% Sport Cashback Bonus
The 5% Sport Cashback Bonus gives you a second chance by refunding a portion of your losses on sports bets. This offer applies exclusively to sports betting and is available without any wagering requirements, meaning you can either withdraw the cashback or use it to place new bets on Sirwin crypto betting markets.
One of the unique aspects of this cashback is how it’s handled at withdrawal. It won’t affect your withdrawal if you’ve only claimed one cashback in the last 24 hours. However, if you’ve received multiple cashback discounts, those bonuses will be deducted from your balance when you cash out.
Key Terms:
- Cashback applies only to sports betting losses
- Cashback funds can be withdrawn or used immediately
- Your balance must be below $1 with no unsettled bets to qualify
- Requests must be made within 48 hours of losses
- Only one bonus per deposit is allowed, and bonuses can’t be combined
