A Romanian online casino with a very large 5-deposit welcome package
Visit Winboss Casino →Winboss 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.

- A very large welcome package worth up to RON 10,000

Our verdict
Winboss Casino is operated by Crowd Entertainment Limited (Malta), holding ONJN Class I licence L1213823W001269, independently confirmed by a second review domain. New Romanian players get a very large welcome package up to RON 10,000 plus 1,500 free spins across their first 5 deposits. However, the 40x wagering requirement must be completed within just 7 days — a tight window that reduces the offer's practical value.
