Slim King at a Glance

Bonuses and Promotions

Slim King runs separate welcome offers for the casino and the sportsbook, then supports existing accounts with cashback and reload deals. Each promotion carries its own terms and most require an opt-in rather than being applied automatically.

Primary Welcome Bonus

The Casino Welcome Pack is worth up to 350% up to €10,000 plus 500 free spins across the first four deposits. The first deposit returns 100% up to €2,000 with 150 free spins, the second adds 75% up to €2,500 with 50 free spins, the third repeats 75% up to €2,500 with 100 free spins, and the fourth closes the package with 100% up to €3,000 and 200 free spins. Each stage needs a minimum €20 deposit, and free spins arrive in daily batches rather than one block. The offer is for new customers only and must be claimed before any bets are placed with the qualifying deposit.

Additional Promotions

The Sport Welcome Bonus gives new customers a 100% match up to €200 on their first deposit, selected during registration and valid between 21/04/2026 and 31/12/2026. Casino Weekly Cashback returns 15% of net losses up to €3,000 every week. The Weekly Reload Bonus pays 77% up to €700 plus 50 free spins on the first deposit made between Monday 00:00 and Thursday 23:59 UTC and requires a weekly opt-in, while a Weekend Reload Bonus of 50% up to €700 plus 50 free spins covers the rest of the week. Tournament prize pools run alongside these offers.

Bonus Conditions Explained

The Casino Welcome Pack carries wagering of 30x on deposit plus bonus and 30x on free spin winnings, with a 10-day window. The maximum bet while a casino bonus is active is €5, cash-out from the welcome pack is capped at 3x the bonus amount, and winnings transferred from free spins are limited to €50. The Weekly Reload Bonus uses 35x wagering on deposit plus bonus and on free spin winnings, allows a maximum win of 5x the bonus, gives three days for wagering and expires the free spins after two days. The Sport Welcome Bonus works differently: 7x wagering on the bonus amount using qualifying sports bets, a maximum transfer to the real balance of €1,000, activation within seven days of the deposit and 30 days to finish wagering. Cashed-out bets, voided bets, singles at odds below 1.90 and multi selections at odds of 1.51 or lower do not count towards sports wagering. Casino bonuses cannot be combined with other offers, and promotions may be modified or terminated at any time.

1. Register an account or log in with your existing username and password.
2. Opt into the casino or sports welcome offer during registration.
3. Open the cashier and select a payment method.
4. Enter an amount of at least €20 to qualify for a welcome bonus.

Payment Methods and Limits

Slim King processes payments in euros and lists its limits before a deposit is confirmed, both on the payments page and inside the bonus terms. The table covers every published method, including the single withdrawal route.

Deposit Options

Every method starts at €10, so the entry point is the same for cards, bank accounts, vouchers and coins. Visa and Mastercard payments are instant and fee-free with a €2,000 ceiling per transaction. Bank options give the highest limits: Sparkasse, VR-Banken and Deutsche Bank each accept up to €9,000, while the general Bank Transfer route is capped at €4,000. Revolut has the lowest ceiling at €999, Paysafecard reaches €2,000, and the seven crypto options each allow up to €5,000. Bonus eligibility begins at €20, not €10.

Withdrawal Options

Bank Transfer is the only withdrawal method published. Minimum and maximum payout amounts, processing times and fees are not stated, so we suggest confirming current figures with support before requesting a payout. Higher withdrawal limits are one of the VIP benefits, and customer due diligence checks may be requested once an account reaches the triggers set by international anti-money laundering rules.
