KnuckleKings Casino Review

Licence and operator

KnuckleKings is owned and operated by 3-102-949193 SRL, registration number 3-102-949193, San José, Catedral District, 11th Street, No. 664, Costa Rica. The T&Cs (last updated by the operator on 11 September 2026) and the site footer both name this company. The footer says knucklekings.com is licensed and regulated by the Government of the Autonomous Island of Anjouan, Union of Comoros, under licence number ALSI-202608032-FI2.

Anjouan is an offshore licence. A named regulator and a published licence number are better than nothing, but this is not the level of player protection you get from the UK Gambling Commission or the Malta Gaming Authority, and there is no comparable complaints process. The footer lists a contact email (contact at knucklekings.com). You must be 18 or older.

Who can play

Section 4.1.3 of the T&Cs lists the countries where you may not open or use an account. The main markets on that list are Germany, Austria, France and its overseas territories, the Netherlands and its overseas territories, Spain, the United Kingdom, the USA and its territories, Australia and the Union of Comoros.

Also excluded: Iran, Myanmar, North Korea, Western Sahara, Burundi, the Central African Republic, Eritrea, Guinea-Bissau, Haiti, Libya, Nicaragua, Somalia, South Sudan, Sudan, Venezuela, Yemen, and any country under comprehensive international sanctions.

The T&Cs also exclude every country on the FATF black and grey lists, as FATF updates them. On the FATF lists of 19 June 2026 that adds Angola, Bolivia, Bosnia and Herzegovina, Bulgaria, Cameroon, Côte d'Ivoire, the Democratic Republic of the Congo, Iraq, Kenya, Kuwait, Laos, Lebanon, Monaco, Nepal, Papua New Guinea, Syria, Vietnam and the British Virgin Islands. FATF revises these lists several times a year, so check the current version.

Ukraine is not excluded as a whole: only the Donetsk, Luhansk, Zaporizhzhia and Kherson regions are. The minimum age is 18, or higher where local law requires it. Section 3.4 bans VPNs, proxies and any similar tool that hides your real location, so do not try to get around a country block.

Welcome package

The bonus terms (last updated by the operator on 18 September 2026) describe a Welcome Package of four deposit bonuses in a row. Each needs a deposit of at least €20. No bonus code is needed: after a qualifying deposit, the bonus appears under My Bonuses and you activate it there.

First deposit: 100% up to €500. Second deposit: 75% up to €500. Third deposit: 50% up to €500. Fourth deposit: 25% up to €500.

Worked example from the bonus terms: you deposit €100 and get a €100 bonus. Wagering is 35 times the bonus only, not the deposit, so you need to bet €3,500 in total. Unless a promotion says otherwise, the most you can withdraw from bonus winnings is 10 times the bonus, here €1,000; anything above that is removed when you withdraw. You have 30 days to finish the wagering.

While a bonus is active, the maximum bet is €5 per spin or round. Betting more can cost you the bonus and its winnings. At €5 a spin, €3,500 of wagering means at least 700 spins.

Not every game counts in full. Poker, roulette and video poker count 10% towards wagering; other eligible games count 100%. Some games can be excluded or have their own rate.

No free spins are published with this offer. The usual rules apply: one bonus per player, household and IP address, bonuses cannot be combined unless stated, and abuse can cost you the bonus and winnings.

How we score it: Root Score 7.4

Root Score is Bonusjungle's score for a welcome offer, calculated only from its published terms. For KnuckleKings we average the match of the first three deposits: (100% + 75% + 50%) ÷ 3 = 75%. We then use the €500 cap, 35× wagering on the bonus only, the fact that your own deposit is not tied up by the wagering, and the 10× cap on bonus winnings. Those inputs give 7.4. The fourth deposit (25%) is not part of the average.

Root Score does not measure game choice, payout speed, support quality or how long identity checks take. It also does not move with any commission we may earn.

Payments, withdrawals and identity checks

Deposits, as listed on the payments page: crypto (Bitcoin, Ethereum, Tether, USD Coin, Solana, Litecoin, Tron and Polygon) is instant with a €10 minimum; Visa and Mastercard are instant with a €20 minimum; SEPA bank transfer takes 1–3 days with a €20 minimum. No deposit fees are listed.

Withdrawal times, according to the operator's help FAQ: crypto within 1–2 hours, Visa and Mastercard 3–5 business days, SEPA 1–3 business days. These are the operator's claims; we have not timed a withdrawal. You must complete identity verification (KYC) before your first withdrawal. The FAQ says this means a government photo ID, a selfie holding it and a recent utility bill or bank statement.

Limits in the T&Cs: the minimum withdrawal is €10 per transaction (section 8.1), although the help FAQ says €20. The maximum is €10,000 per month, or €5,000 per month if your balance is at least 10 times your total deposits (section 8.6). Withdrawals are free if you have wagered your deposit at least once; otherwise the operator can charge 8%, at least €4 (section 8.2). Money goes back to the method you deposited with (section 8.4).

Strengths and limits

Strengths, based on the published terms: a clear first-deposit offer of 100% up to €500; wagering on the bonus only, with a worked example in the operator's own terms; a named company and a published licence number; crypto plus cards and SEPA, with no listed deposit fees; a clear monthly withdrawal limit in the T&Cs.

Limits: the 10× cap on bonus winnings limits what a bonus can pay out; the €5 maximum bet makes €3,500 of wagering slow; 30 days is not long; Anjouan is an offshore licence; VPNs are banned; many countries cannot play, including Germany and every FATF-listed country; no free spins; the minimum withdrawal is €10 in the T&Cs but €20 in the FAQ; withdrawal times are the operator's figures, not ours.

Who it suits and who should skip it

It may suit adults in an accepted country who want a crypto-first casino that also takes cards and SEPA, who are happy with 35× wagering on the bonus, a €5 maximum bet and a 10× cap on bonus winnings, and who accept an offshore Anjouan licence.

Skip it if you live in a country on the list above, if you want a UK- or Malta-style licence, if you would need a VPN to play, if you expect free spins, or if €3,500 of wagering within 30 days on a €100 bonus is more than you would comfortably bet. Gamble only with money you can afford to lose. 18+.
