SlimKing
We built Slim King (written by many UK players as SlimKing) as a casino and sportsbook under one account. Below, in plain English, are our bonuses, games, payment limits, VIP levels and how your pounds are handled.

Currency: Euros and Your Pounds
Accounts at Slim King are held in EUR, the only currency we support. When you fund an account in pounds, your bank or card issuer converts GBP into euros at its own rate and may add a conversion charge, and the same applies in reverse when a withdrawal reaches your GBP account. Because rates move, the pound figure on your statement will not match the euro amount in our cashier, so check the GBP total your bank quotes before confirming a payment. All caps, minimum deposits and maximum bets below are euro figures.
SlimKing Sign Up and SlimKing Login
Opening and accessing an account takes a few minutes. Registration runs across three short steps, age verification applies from the outset, and anti-money laundering checks are requested once an account reaches the relevant triggers.
How SlimKing Sign Up Works
Step one is an email or username and a password, step two your country and currency, step three personal details such as name, address and phone number. You must be at least 18 to open an account, and we verify age. Customer Due Diligence checks are requested when an account reaches the triggers set by international AML regulation.
SlimKing Login and Password Help
The SlimKing login uses your username and password. If you forget your details, password recovery runs through our support email at [email protected].
Your First Deposit
- Register or log in.
- Open the cashier or deposit section.
- Choose a payment method and enter an amount (minimum €20 if you want a bonus).
- Complete the payment.
- Your bonus is credited immediately or activated in the "My Bonus" section, which is how the Welcome offer works.
Minimum deposits are shown before you pay, on the payments page and in the bonus terms: €10 for most methods, €20 to claim a welcome offer.
SlimKing Bonus Offers
Our promotions split into a four-part casino welcome pack, a sports welcome bonus, weekly cashback and two reloads. Each carries its own wagering requirement, maximum bet, win cap and time limit, all quoted in euros. Welcome offers need a qualifying deposit of at least €20, and bonuses cannot be combined.
Casino Welcome Pack and SlimKing Free Spins
New customers can claim 350% up to €10,000 plus 500 SlimKing free spins across the first four deposits: 100% up to €2,000 + 150 FS, then 75% up to €2,500 + 50 FS, then 75% up to €2,500 + 100 FS, then 100% up to €3,000 + 200 FS. The minimum deposit is €20 and free spins are credited in daily batches. Wagering is 30x (deposit + bonus) and 30x on free spin winnings, with a €5 maximum bet, a cash-out cap of 3x the bonus, €50 maximum transfer from free spin winnings and 10 days to complete play. It must be claimed before any bets are placed with the qualifying deposit.
Sport Welcome Bonus
Opt in during registration for 100% up to €200 on your first deposit, with a €20 minimum. Wagering is 7x the bonus on qualifying sports bets; cashed-out and voided bets are excluded, as are singles under odds of 1.90 and multiple selections at odds of 1.51 or lower. The maximum transfer to your real balance is €1,000. You have 7 days from the deposit to activate the bonus and 30 days to complete wagering. The promotion runs from 21/04/2026 to 31/12/2026.
Cashback and Reloads
Weekly cashback returns 15% of net losses, up to €3,000 each week. The Weekly Reload gives 77% up to €700 plus 50 free spins on your first deposit between Monday 00:00 and Thursday 23:59 UTC, with 35x wagering on deposit plus bonus and on spin winnings, a €5 maximum bet, a 5x bonus cap on wins, 3 days to wager and spins that expire after 2 days. The Weekend Reload is 50% up to €700 plus 50 free spins. Reloads need an opt-in each week and are open to all registered users.
Is There a SlimKing No Deposit Bonus?
We do not currently list a SlimKing no deposit bonus. Every offer above requires a qualifying deposit, so no promotion here gives money without a payment, and no bonus removes the risk of losing your stake.
