Final Verdict

OnlyWin is a Curacao casino operated by Goodfly N.V. that offers over 1,600 games from 116 providers, including one of the biggest live casino line-ups in Canada with more than 200 live dealer games, and 15 banking methods across cards, e-wallets, Interac and crypto. However, its reputation has collapsed: having won awards and held a safety rating around 9.3, it fell to about 2.8 within a year after refusing to honour legitimate winnings, including blocking a player’s account on shifting, unsupported allegations and declining to pay despite disproving evidence. We would urge strong caution: the games and live casino are good, but the documented refusal-to-pay complaints make this a high-risk choice for anyone hoping to withdraw meaningful winnings. Draft, pending GC review.
