Our verdict
We want to report the most serious findings directly. AskGamblers documents that Millioner - operated by Lumina Holdings Limitada under a Costa Rica gambling licence since 2025, the same operator we identified for Monsterwin earlier this session - has a EUR7,648 jackpot win that remained unpaid for months, alongside a documented self-exclusion enforcement failure, a pattern we treat with severity given the harm self-exclusion protections exist to prevent. Withdrawal limits are also notably low (EUR500/day, EUR7,000/month), and a separate complaint documents a EUR34 payout error on a roulette spin with a 200x multiplier. Of 5 total complaints, 2 remain unresolved. On a more neutral note, the casino offers over 9,000 games from around 80 providers, 24/7 live chat, and support in 16 languages. We could not corroborate this review with a second source this session, as casino.guru had no dedicated review page. Norway has no locally regulated welcome bonus for this brand, given its state monopoly.

24/7 live chat offered, per AskGamblers, but the same source documents struggling withdrawal processing and customer-service responsiveness.
Trust & licensing (27%)1.5
SEVERE: AskGamblers documents a EUR7,648 jackpot win left unpaid for months and a self-exclusion enforcement failure, alongside low withdrawal limits (EUR500/day, EUR7,000/month). Same operator (Lumina Holdings Limitada) as Monsterwin, a disclosed multi-brand pattern; genuinely new brand (2025) with only 5 complaints filed so far, 2 unresolved.
Bonuses & value (18%)1
No locally regulated welcome bonus - Norway runs a Norsk Tipping/Norsk Rikstoto state monopoly, so any offer is only via the offshore .com site.
