What Are Free Spins for Existing Players?
Free spins for existing players are bonus spins offered to accounts already registered with an online casino. Unlike welcome bonuses aimed at new sign-ups, these run as ongoing campaigns that reward players for staying active, rather than as a one-off deal.
UK players may receive them in several ways:
- Loyalty or VIP rewards, where points you earn from playing can be swapped for free spins.
- Promotional emails or account offers, sent to selected players rather than everyone.
- Seasonal promotions, tied to holidays or other calendar events.
- Game promotions, spins awarded for playing selected slots, usually new releases.
For example, a casino may credit 10 free spins for existing customers on a promoted slot during a weekend campaign or after completing a short in-game challenge.
Free spins for existing customers can disappear within 24 hours, so check the promotions page when you log in.

Why Online Casinos Offer No Deposit Free Spins for Existing Players
Online casinos run these promotions mainly for retention, to keep players from drifting to a competitor's site. A player who stays active is worth more to a casino long-term than one who signs up once and disappears.
Casinos also use free spins for existing customers to bring back players who've gone quiet, sometimes months after they last logged in. For you, it means bonus spins on games you already enjoy, without having to make a new deposit or sign up somewhere else.
Different Types of Free Spins No Deposit for Existing Players
Though they look similar, most existing player bonuses have slight differences, whether in the bonus terms and conditions or the linked casino games. Each type below works slightly differently, so it's worth knowing which one you're looking at before you claim.
Tournaments
Online casinos run entertaining tournaments and competitions – sometimes in collaboration with the best game developers. Depending on the promo, you will most likely need to play games and collect points to get free spins.
Players can usually join tournaments by opting in through the casino promotions page and playing the selected slot games during the event period. Points are typically awarded based on gameplay activity, with leaderboards ranking participants. Perfect if you have a competitive streak.
Log in and Daily Free Spins
Certain casinos offer small daily free existing customers can get just for logging in or being active. These offers tend to track gaming streaks automatically and provide free spins, often without any need for the players involved to claim them.
They can also come in the form of a free spins code existing customers can enter to claim. This is unlike the automatic crediting, as the casino sends an email with the code or notifies you via a message in your account. The code tends to be time-sensitive, making it necessary to keep checking the messages.
The wagering requirement and game restrictions should be checked before using any bonuses or promotional offers. Eligible slots may also be limited to selected titles.
For example, say you get 20 free spins worth £0.10 each and win £5. With a 10x wagering requirement, you'd need to place £50 in bets (£5 x 10) before you can withdraw. If you keep playing at £0.10 a spin, that's 500 spins. Any wins along the way are added to your balance, and you can withdraw once you've wagered the full £50.
Bonus Spins for Adding a Card
You can receive free spins for adding your debit card details, where a casino credits spins once you've added a debit card to your account. Your card won't be charged, this is purely a verification step.
More casinos are adding this option to their existing-customer offers. You'll usually need to opt in and validate the card yourself, rather than it happening automatically. Read the terms carefully, as e-wallets are often excluded from these offers, so Neteller and Skrill usually won't qualify.
Bonus Spins for a Deposit
You can also claim free spins for existing customers by making the minimum deposit shown on that specific promotion. The spins are usually tied to one particular slot.
For smaller promotions, up to around 50 spins, you might only need to deposit £10 to £20 to qualify. Not every payment method counts though, so check the terms before you withdraw any winnings.
Seasonal Promotions
Seasonal promotions are free spins or bonus offers tied to specific tiSeasonal promotions are free spins or bonus offers tied to specific times of the year or calendar events.
Examples of themed promotions include:
- Christmas
- Halloween
- New Year
- Chinese New Year
- Summer bonuses
- First-of-the-month rewards
- Sports events
These promotions usually come with standard terms such as game restrictions, expiry periods, and wagering requirements. Players should always check the eligible slots and that free spins valid before they play.
Free Spins Code Existing Customers
A free spins code existing players offer means that rather than automatically getting your spins, you will first have to enter a code on the promotions or cashier page. The casino sends the free spins code via its marketing emails or promotions page. Without the code, the offer remains locked.
The difference between no-deposit and deposit codes lies in what you commit first. A free spins existing customer no deposit code is executed without the need for a payment, whereas a deposit code involves funding your account first. No-deposit versions are rarer because the casino carries the full cost without any deposit to offset it.
Whether you're looking for no-deposit codes or deposit-based free spins, stick to licensed operators with a solid reputation. If you fancy trying somewhere new, our casino UK new page is a good place to start.
How to Activate a Casino Promo Code for Existing Customers
Activating free spins codes for existing players is usually straightforward, but the process can vary depending on how the code is delivered. Codes may come directly from the casino, through affiliates like Mr. Gamble, or via promotional emails.
If your code comes from the casino's own promotions page, this is what to do:
- Log in to your existing account
- Go to the promotions or cashier section
- Enter the promo code in the designated field
- Confirm and claim the bonus
If the code arrived by email, here's how to use it:
- Open the email containing the bonus code
- Click the link or copy the code
- Log in to your account and enter the code if required
- Check that the spins or bonus have been credited
If you're activating a code through Mr. Gamble, follow these steps:
- Click 'PLAY' to visit the casino's site
- Complete any registration or login required
- Enter the promo code when prompted, or follow the on-page instructions if there's no separate code to enter
- Confirm the bonus has been applied before you start playing
How Many Free Spins Can You Get As an Active Customer
Not all free spins for existing customers are worth the same amount of play. Here's what each spin count typically gets you.
- 5 free spins. It doesn't sound like much, but 5 free spins is enough to try a new game and decide if you'd want to play it with your own money.
- 10 bonus spins. This is arguably the most common amount you'll see offered to existing customers.
- 20 free spins. Some casinos offer 20 free spins no deposit deals, though they're harder to find than 5 or 10 spin offers.
- 25 free spins. A middle-ground amount, more play than 10 spins, without being as rare as 50. Some casinos reward loyal players with 25 no deposit free spins through weekly promotions.
- 50 extra spins. If 5, 10 or 20 spins aren't enough, look for casinos offering 50 spins to existing players. It's one of the more generous amounts you'll find.
Best Slots to Play With Your Free Spins for Existing Customers in the UK
Free spins are usually tied to specific slots rather than any game you choose, and UK players tend to have firm favourites among providers like NetEnt and Microgaming. Here are some of the most popular slots that free spins for existing customers are usually offered on.
- Starburst is a NetEnt video slot with a simple 5-reel, 10-payline setup. You line up matching gems across a payline to win, and landing a wild expands it and can trigger a multiplier as well as a respin.
- Gonzo's Quest follows Gonzalo Pizarro into the South American jungle, with the Avalanche feature clearing winning symbols to bring in new ones and build up multipliers.
- Chilli Heat is a Pragmatic Play slot with a free spins bonus round, jackpots and a Money Respin feature.
- Big Bass Splash, also from Pragmatic Play, is built around a fishing theme, with multipliers, scatters, retriggers and free spins on offer while you fish.
- Gates of Olympus 1000 puts you up against Zeus, with high volatility and multipliers that build up during the free spins round.
- Book of Dead, from Play'n GO, follows adventurer Rich Wilde through Ancient Egyptian tombs, with expanding symbols and scatters during free spins.
