The main Slimking bonus is the Casino Welcome Pack: 350% up to about £8,600 plus 500 free spins, spread across the first deposits, with a minimum deposit of about £9. Sports bettors can choose a 100% match up to about £170 instead. After the welcome period, the casino runs a Weekly Reload of 77% up to £600 + 50 free spins, a Weekend Reload of 50% up to £600 + 50 free spins and 15% weekly cashback up to £2,600, plus a coin-based Store, Challenges, Collections, Tournaments and a Lucky Wheel. Wagering requirements and maximum bet rules are listed on each offer and should be checked before claiming. Slimking is not licensed by the UK Gambling Commission, so UK rules on bonus terms do not apply.
All promotions are advertised in euros on the site; the pound amounts on this page are approximate equivalents and will move slightly with the exchange rate.

Slimking welcome bonus for casino players
The Casino Welcome Pack is the default choice at registration: it is preselected in the bonus dropdown at the top of the sign-up form. The 350% headline figure is the total match across the package, and the 500 free spins are released alongside the deposit bonuses. The exact split per deposit appears in the offer terms under "Read more" on the Bonuses page.
To see how a deposit match works, a 100% match on a £100 deposit adds £100 in bonus funds, so the balance shows £200. A 150% match on the same deposit adds £150, giving £250. Bonus funds and free spin winnings stay locked until the wagering requirement is met, and only then can they be withdrawn.
Key conditions checklist
Before the first deposit with the welcome pack, the following points in the offer terms deserve a close look.
- Minimum deposit for each stage of the pack.
- Wagering requirement and whether it applies to the bonus only or to deposit plus bonus.
- Maximum bet per spin while wagering.
- Games that are excluded or contribute less than 100%.
- Time limits for activating the bonus, using free spins and finishing wagering.
- Any cap on winnings from free spins.
Slimking sports welcome bonus
Sports bettors can switch the registration dropdown to the Sport Welcome Bonus: 100% up to about £170. A £100 first deposit becomes £200 to bet with, and a deposit of £170 or more takes the full amount. The sport and casino welcome offers are alternatives, so choosing one rules out the other on the same account.
Weekly Reload Bonus
The Weekly Reload adds 77% up to about £600 plus 50 free spins. A £200 deposit gives £154 in bonus funds, for a total of £354, while a deposit of around £780 reaches the £600 cap. The reload runs on a weekly cycle and has its own terms on the offer page.
Weekend Reload Bonus
The Weekend Reload adds 50% up to about £600 plus 50 free spins. A £200 deposit gives £100 extra, and the full £600 is reached with a deposit of about £1,200. It suits players who deposit mainly at weekends, while the weekly reload offers a higher percentage for mid-week deposits.
Casino Weekly Cashback
Weekly cashback returns 15% of net losses in the Casino section, capped at about £2,600. A week with £200 in net losses returns £30; £1,000 in net losses returns £150. Live casino, sports and virtual sports do not count towards the calculation, so the cashback is aimed squarely at slot and RNG game players.
How Slimking Challenges, Collections and the Store work
Slimking runs a coin economy alongside the cash bonuses. Coins are earned by completing tasks and spent on rewards, which makes regular play add up even without a deposit bonus.
- Open Challenges from the Bonuses page and check the week's casino and sport tasks.
- Complete tasks such as spinning Gates of Olympus Super Scatter or Big Bass Splash at a minimum bet of about £0.25; each casino task pays 3 coins.
- Finish 20 casino challenges for a 50-coin bonus, or 30 sport challenges (minimum stake about £13, odds 1.5-2.0) for 50 coins.
- Unlock cards in Collections; completing the Football Clubs set releases a cash reward of about £4.
- Spend coins in the Store on free spins, bonus money or sports free bets.
Store prices give a sense of value: 10 free spins on 2 Wild 2 Die, Wanted Dead or a Wild or Book of Ra Deluxe cost 50 coins; bonus money costs 50 coins for about £4, 90 coins for £9, 150 coins for £17, 220 coins for £26 and 320 coins for £43. A sports free bet of about £9 costs 90 coins. Larger bundles give slightly more value per coin.
Slimking tournaments
The Tournaments page lists active and finished events, each with a prize pool, a minimum qualifying bet and a countdown. The table shows typical formats.
| Tournament | Section | Prize pool | Minimum bet |
|---|---|---|---|
| Sports | Sport | About £1,300 | About £9 |
| Slot Highlights | Casino | About £950 | About £0.45 |
| Rotating casino events | Casino | Shown on each card | Shown on each card |
The "See details" panel under each tournament explains the scoring method, eligible games and the prize split between leaderboard places.
Slimking bonus terms and wagering rules
Each offer has its own terms, and the details are shown behind the "Read more" button. The table summarises the parameters that matter most and where to find them.
| Parameter | What to check |
|---|---|
| Wagering requirement | Listed on each offer; check whether it applies to bonus or deposit + bonus |
| Eligible games | Slots usually count in full; table and live games often excluded or reduced |
| Maximum bet during wagering | Per-spin cap; exceeding it can void bonus winnings |

How to claim a Slimking bonus
Claiming the welcome offer starts at registration, while reloads are claimed from the Bonuses page.
- Click REGISTER and pick the Casino Welcome Pack or the Sport Welcome Bonus in the dropdown.
- Use "I have a promocode!" only if a valid code is available.
- Complete both registration steps.
- Open the cashier and make a deposit of at least the minimum stated in the offer.
- Check that the bonus and free spins appear in the account.
- For reloads, open the Bonuses page, read the terms and deposit within the offer window.
Which Slimking bonus to choose
The best offer depends on how and how much a player plans to play.
- Slot players with a larger budget: the Casino Welcome Pack gives the most value, but the high match also means a larger wagering volume.
- Sports bettors: the 100% Sport Welcome Bonus up to £170 fits better, since casino bonus funds usually cannot be used on sports.
- Mid-week depositors: the 77% Weekly Reload beats the 50% weekend offer on percentage.
- Players who prefer no wagering pressure: skipping the welcome bonus and relying on cashback and Store rewards keeps withdrawals free of bonus restrictions.
- Regular low-stakes players: Challenges and the Store reward volume rather than deposit size.
Slimking VIP programme
The VIP programme has five levels. Level 1 includes on-site promotions and 24/7 live chat access; Level 5 adds personalised offers, higher withdrawal limits, cashback and a personal VIP manager. Progress depends on activity within a set period, and the VIP manager at higher levels can tailor bonus offers to playing habits.
