SlimKing Sign Up and Login

You register in three steps, log in with your username and password, and send documents only when verification is triggered.

Opening an Account

We ask for an email address or username, a password, your country and currency, and your name, address and phone number. You must confirm that you are at least 18, and we verify your age. You can opt in to the Sport Welcome Bonus during this process.

SlimKing Login and Password Recovery

Your SlimKing login uses your username and password. If you lose access, email [email protected] and we will help you reset your password.

Verification

We request Customer Due Diligence documents when an account reaches the triggers set by international anti-money-laundering regulation.

Deposits and Withdrawals

We accept 15 deposit methods. The minimum is €10 for most options, while €20 unlocks our bonus offers.

Visa and Mastercard deposits arrive instantly with no fee from us. Withdrawals are currently processed by bank transfer.

VIP Programme and Tournaments

Regular play is rewarded two ways: a five-tier VIP ladder and our tournament schedule.

Five VIP Levels

Our ladder runs from Level 1 to Level 5. Benefits include on-site promotions, 24/7 live chat access, personalised offers, higher withdrawal limits, cashback and a personal VIP manager. We do not operate a separate points-based loyalty scheme.

Tournaments

Our tournament formats are Slot Highlights, Spin Arena, Live Stakes and Sports. Casino prize pools range from €1,100 to €2,500, while sports tournaments carry a €1,500 pool.

Mobile Play

There is no iOS or Android app to download. Our responsive site adapts to your screen, so the lobby, cashier and sportsbook open in your mobile browser.

Sports Betting

Our sportsbook covers pre-match, live and in-play betting plus virtual sports. The most popular markets are football, tennis, Dota 2, Counter Strike, ice hockey, rugby, baseball, American football, table tennis and basketball. Horse racing, live streaming and cash-out are not available at the moment.

Support, Security and Safer Gambling

Live Chat is staffed 24/7 and you can write to [email protected]. We support English, German, Spanish, Polish, French, Greek, Italian, Danish, Czech, Hungarian, Finnish and Portuguese.

For safer gambling we offer self-exclusion, while deposit limits and loss limits are not part of our tools at present. You must be 18 or over to hold an account.
