Dunder is a Scandinavian-facing online casino that first went live in 2016, built by Swedish co-founders led by Olof Örn and powered by the Gaming Innovation Group / MT SecureTrade platform. The brand quickly made a name for itself with a clean, simple interface and one of the largest multi-provider lobbies in Europe, covering slots, table games and a full Evolution-powered live casino.
The casino has operated under respected licences from the Malta Gaming Authority and the Swedish Gambling Authority, and it previously held a UK Gambling Commission licence before exiting the UK market in 2020. Over the years it has added thousands of titles from studios like NetEnt, Microgaming, Play’n GO, Red Tiger, Blueprint, Thunderkick and many others, with some regions reporting 1,800+ games at peak.
On the downside, Dunder’s reputation is not spotless. While many players praise the fast e-wallet withdrawals and straightforward bonus rules, complaint boards and review sites also show repeated issues with delays on bank withdrawals, strict KYC checks, account closures during investigations and frustration with support queues. In some markets the official site now displays a closure or “not accepting new players” message, so availability in 2025 is very region-dependent and you should always double-check the status for your country before trying to register.
