Casino bonuses and promo codes
At SpinMills, we understand that a rewarding start and consistent value are essential to your gaming experience. That’s why our bonus system is structured to give players in the UK a fair, transparent, and exciting journey across every stage—from the very first deposit to high-tier VIP perks.
As a fully licensed online gambling platform, we operate under a valid gaming license that ensures player protection and fairness. All of our casino bonuses are tailored for UK residents, meaning you’ll only see offers relevant to your region and currency. Our promotional banners are clearly displayed on-site, showing exact bonus amounts, eligible games, and expiration times. Whether you're spinning on slots or competing in live tournaments, we provide value in every interaction.
The following sections explain each bonus type in detail, based on what’s currently active for UK users. We update these regularly, and all bonuses are available through desktop and mobile. Screenshots of current offers are available on our promotions page and within your account dashboard after login.
Bonus Types
SpinMills provides a structured bonus system built around deposit incentives, loyalty milestones, and limited-time extras. Every promotion we release includes clear terms and contributes to your broader player journey. We know that not everyone plays the same way—so our bonuses are flexible.
Players can benefit from:
- Welcome rewards with free spins
- Reload offers such as Friday bonuses
- Cashback on net losses
- Slot missions with real prizes
- Live casino tournaments
- Loyalty progression through our VIP program
We also issue occasional promo codes that unlock special events or hidden promotions. Some are public, others sent directly to player inboxes. You’ll find deposit bonuses ranging from 20% to 100% and, occasionally, even a no deposit bonus—these are often time-sensitive.
Our system rewards regular play. You collect points every time you wager, gradually unlocking VIP levels. Higher tiers come with exclusive bonuses, gifts, and real cash events. Whether you're a casual player or a seasoned high roller, our gambling site licensed by international regulators ensures your rewards are fair and your information secure.
Welcome Bonus
The SpinMills welcome package is designed for new players ready to start strong. You’ll receive a 100% bonus for newbies up to £500, plus 200 free spins. Spins are delivered in daily batches of 20 across 10 days, each tied to high-RTP games like Cursed Seas or Forge of Fortunes.
To activate the bonus, a minimum deposit of £20 is required. Bonus funds and winnings from free spins are subject to a 35× wagering requirement. This offer is available across desktop and mobile devices, and no bonus code is needed—just opt-in during registration.
First Deposit
The SpinMills first deposit bonus is the core of your welcome journey. As soon as you make your initial deposit of at least £20, we double your amount with a 100% match, giving you up to £500 in bonus funds. In addition, you receive 200 free spins, distributed in sets of 20 per day over 10 days.
You don’t need any SpinMills bonus code to activate this offer—just tick the bonus box during registration. Bonus funds must be wagered 35×, and free spins winnings have the same condition. This minimum deposit threshold ensures broad accessibility while still offering excellent value. The SpinMills bonus applies automatically once the transaction is confirmed.
Second Deposit
The second step in your welcome journey comes with another valuable boost. When you make your second deposit, SpinMills rewards you with the second SpinMills bonus, often a 50% or 75% match up to £250, depending on the week’s promotion.
This bonus is typically activated automatically, but always check whether a SpinMills bonus code is required for that week. Your reward amount depends on how much you deposit, starting at a minimum of £20. Spins or cashback may also be included as part of this second-tier bonus, and standard wagering applies.
Special Bonus / Loyalty Package
Our SpinMills bonus system is most rewarding for returning players. Beyond your welcome package, we offer consistent weekly rewards, including free spins, match bonuses, and special promotions tied to seasonal events or game releases.
Loyal users enjoy loyalty reward for gamblers who actively engage with the platform. Once you begin earning VIP points, you enter our five-tier VIP program:
- Bronze: 20% deposit bonus + 20 free spins/month
- Silver: 30% bonus + 50 spins + faster withdrawals
- Gold: 40% bonus + 100 spins + personal VIP host
- Platinum: 50% bonus + 200 spins + exclusive gifts
- Diamond: 75% bonus + 500 spins + luxury event invites
Each level brings new perks, and your SpinMills bonus code access may include exclusive spins, cashback, and birthday rewards. Loyal players also receive faster withdrawal speeds, priority support, and invites to private VIP tournaments.
Tournaments
We love giving our players a competitive edge. At SpinMills, our weekend tournaments bring live games to life. Join our Friday-to-Sunday Live Casino Tournaments and compete for cash pools of up to £5,000. Titles like Speed Roulette, Blackjack Azure, and Lightning Baccarat are usually in play.
Leaderboard rankings are based on win streaks and total bets. If you place in the top 20, you’ll receive bonus funds with low wagering (often just 1×) or direct cash prizes. Every tournament comes with a unique SpinMills bonus for top performers, and participation is open to all real-money players.
Promo Codes
We issue SpinMills promocodes as part of seasonal campaigns, holidays, or platform updates. These codes give players access to extra spins, cashback, or limited-time enhancements to existing deals.
Where to find them?
- On our official promotions page
- Via email newsletters
- Occasionally through affiliate partners or social media
While most bonuses don’t require a code, we may release unique no deposit bonuses through private channels. Keep your notifications turned on, and don’t forget to check your “My Offers” page regularly.
No Deposit Bonus
Some of our most appreciated offers are no deposit bonuses, and SpinMills occasionally releases them during key promotions or player anniversaries. These allow you to try out new games or test the platform—no funding required.
Typically, this bonus includes 10–20 free spins or a small amount of bonus credit (£5–£10). They come with a modest wagering requirement (25×–35×), and are only available to newly registered or returning verified players.
Because they’re time-sensitive and limited in volume, we recommend checking your dashboard regularly. When available, they offer a great risk-free opportunity to explore and win.
