OnLuck raises red flags in our safety check. Below we show which ones, how it compares with other casinos and safer options to consider.
Our verdict on OnLuck
Our verdict: proceed with caution at OnLuck. Its license, safety score or blacklist status raises red flags.
- Safety Index 3.2/10, among the lowest we track (higher than only 11% of casinos).
- Mid-level license from Curacao Gaming Authority: valid, with lighter supervision.
- Terms rated fair: no clauses that let the casino keep winnings without reason.
- 53% of complaints were resolved, at least as many as at the typical casino (32%).
- Running since 2023 (3 years).
Does OnLuck have a valid license?
OnLuck is licensed by Curacao Gaming Authority (Curacao) and Anjouan Offshore Finance Authority (Comoros (Anjouan)).
License number: OGL/2024/1178/0479, ALSI-202410047-FI2. You can look it up on the regulator's public register.
Curaçao reformed its licensing in 2023: the Curaçao Gaming Authority now licenses operators directly and requires a complaint procedure. Supervision is still lighter than in Malta or the UK, so independent safety data matters more.
OnLuck holds 2 licenses in total; the strongest is from Curacao Gaming Authority.
