A genuinely ONJN-licensed Romanian casino with a clean direct record, though its operator's sister brand carries documented complaints

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
Game World Casino holds a genuine ONJN licence (L1213822W001268), operated by Megabet International SRL, a Bucharest-based company established in 2020 that reported strong 2024 growth (net sales up 54.54%, total assets more than tripling). casino.guru gives Game World Casino itself a High 8.5 Safety Index with no relevant complaints found - a genuinely clean individual record. We want to flag something directly rather than stop there: we specifically confirmed via Game World's own Terms and Conditions that Megabet International SRL also directly operates the Mega.Bet brand - this isn't a coincidental name similarity but the same operator group. Mega.Bet carries documented complaints about sports-betting disputes and account-verification delays, where funds were held while an account was placed 'under review'. On the product side, the welcome package is genuinely strong: 100 free spins with no deposit required, plus up to 6,000 RON or 999 free spins spread across 3 deposits. A genuinely licensed Romanian casino with a clean individual complaint record - the documented issues at its operator's sister brand are worth being aware of given the direct operational link.
