An ONJN-licensed Romanian casino with a large multi-deposit package
Visit King Casino →King Casino welcome bonus in Romania
Context for Romania: Romania's check runs the opposite way to most people's instinct, and getting it backwards is the common mistake. The ONJN publishes both a blacklist of unlicensed domains and a WHITE LIST of licensed operators - Class I for operators, Class II for suppliers - and only the white list makes play lawful. A site being absent from the blacklist proves nothing: you will probably still be able to reach it, but playing there is unlawful unless it appears on the white list. The blacklist is large and actively enforced - 1,546 domains have been ordered blocked by ISPs, and Polymarket was added on 29 October 2025. Check any operator against the Class I list at onjn.gov.ro before depositing rather than trusting a licence badge or an affiliate page, this one included. The market is also tightening fast: Law 141/2025, in force from 1 August 2025, raised the annual authorisation tax from 21% to 30% of gross gaming revenue and the minimum annual fee from EUR 400,000 to EUR 480,000; operators need a permanent establishment in Romania and, where their servers sit abroad, mirror servers on Romanian soil giving ONJN real-time access. Advertising rules are moving too - celebrity and influencer endorsements are already banned across TV, radio and social media, Bucharest is removing gambling publicity from city-controlled outdoor sites from 1 January 2026, and the regulator's 2026 agenda proposes raising the gambling age from 18 to 21 plus restricting online promotions between 06:00 and midnight.

Our verdict
There is a date on this page that matters more than the bonus: the licence behind King Casino has passed its expiry and we cannot confirm a renewal. The brand runs on ONJN Class I licence L1160650W000194, held by Level Up Interactive Limited of Malta, which also covers Winmasters, PariuriPlus and 12xBet. That licence ran to 30 June 2026. Renewals in Romania are routine, and we are not telling you the operator is trading unlicensed - we have no evidence of that. But we will not go on describing a licence as current when its stated term has ended and we cannot see a replacement. Why we cannot see it is our problem, not the operator's, and we would rather admit it than imply a check we did not do: ONJN's own site returns 403 to us, so the authoritative Class I list is unreadable from here. That is also why we have not withdrawn the offer - an access failure on our side is not evidence about a company. One thing we are deliberately NOT repeating. Secondary sources describe ONJN complaints, an inspection, a fine and a proposal to suspend this operator's authorisation for up to six months in early 2026. We could not open the underlying page - it sits behind a Cloudflare challenge - and we have been caught before by a search summary asserting a regulatory action the source did not actually contain. So we record that such reports exist and that we have not verified them. That is the honest position: neither publishing them as fact, nor pretending we never saw them. Practical advice: check the Class I list at onjn.gov.ro yourself before you deposit.
How we rated it
Bonuses & value (18%)7.5
A large 4-deposit welcome package up to 4,000 RON, with an alternative of up to 1,700 free spins — flexible and generous.
Casino (36%)6.8
Genuine ONJN-licensed Romanian operator.
Customer support (18%)6.3
No major documented complaint pattern found.
Trust & licensing (27%)6
A real positive: genuine ONJN licence (L1160650W000194), which EXPIRED on 30 June 2026 with no renewal we could confirm. Held back because we could not confirm this brand on ONJN's Class I white list - the only check that establishes lawful play in Romania. The regulator's licensee page was unavailable and no independent source gave a Class I number. This records a gap in our verification, not a finding against the operator. Marked down because the licence we cite EXPIRED ON 30 JUNE 2026 and we cannot show a renewal - not an accusation, since renewals are routine and ONJN's register is unreachable from here, but we will not score a permission we can no longer verify as current.

About King Casino
King Casino is a Romanian brand running on ONJN Class I licence L1160650W000194, held by Level Up Interactive Limited (Malta), which also covers Winmasters, PariuriPlus and 12xBet. That licence ran to 30 JUNE 2026 - a date now in the past - and we have not been able to confirm a renewal. Renewals are routine and this is not a claim that the operator is trading unlicensed, but we will not describe the licence as current when we cannot see that it is. The reason we cannot check is our own access problem, stated plainly: ONJN's site returns 403 to us, so the authoritative list is unreadable from here. Check the Class I list at onjn.gov.ro yourself before depositing.
