Our verdict
Ultrabet is a brand operated by Suprema Bet Ltda, which replaced the earlier XPBet brand and holds a genuine SPA/MF federal authorization (No. 2.104-20); Suprema Bet also operates sibling brands Supremabet and Maximabet. Reclame Aqui shows a 7.2/10 rating with the verified-company trust seal across 1,017 complaints, with a 96.2% response rate and 71.7% resolution rate - though the average response time is a slow 15 days 3 hours. We want to report specific, serious documented complaint themes directly: withdrawal blocks tied to a stated up-to-30-day security review, bets and account balances disappearing from the platform without explanation, persistent access errors preventing platform use, misleading bonus offers that never arrive, and - most concerning - accounts specifically blocked after players achieve consistent wins. For Brazil specifically, no welcome or deposit bonus is available at all, since Law 14.790/2023 Art. 29 and SPA/MF rules ban these for all licensed operators there since 1 January 2025 - a market-wide restriction, not specific to Ultrabet. A genuinely licensed operator, but the specificity and severity of the documented withdrawal-blocking and post-win-restriction complaints warrant real caution.
