Dunder is a virtual casino venue which opened in early 2016. It has Swedish origins, hence the name Dunder (“thunder” in Swedish). The founders are experienced individuals and they know their games and product variations. MT SecureTrade Limited is the operator company, which also provides a Maltese license. For UK players, the casino has obtained a UKGC license, as well.

A fantastic online casino, Dunder has a great welcome bonus and a huge collection of games assembled by some of the most acclaimed software providers in the business. The site packs over 1,800 slots, table games, live dealer games, keno, scratch tickets and more.

Dunder Casino Gaming Categories and Software Providers

The lobby at is rather unconventional. Instead of showcasing a handful of categories that simply divide the games by type, Dunder introduces numerous subcategories and more precise parameters to choose a group of games to browse. For instance, one can open a page entitled “Stacked Wilds”, “Win Both Ways” or “Bonus Bets” and choose among titles with these features.

It’s evident that the website is extremely mobile-friendly and the games are loaded with one tap or click. Through links with NetEnt, Play‘n GO, Microgaming, Yggdrasil, Rabcat, Big Time Gaming and Quickspin, Dunder customers have access to their catalogue of classics and new releases. In one place, you can play Mega Fortune, Hall of Gods, Book of Dead, Pirate 21, Single Deck Blackjack, Mayan Bingo and Live Dream Catcher – and much, much more.

Dunder Casino Bonuses and Promotions

As far as welcome parties go, Dunder is over the top. New customers get 20 free spins for Book of Dead on registration. Furthermore, they get a 100% bonus up to £100 with 50 free spins on the same popular slot Book of Dead on your first deposit. Those who log in back the next day, get another fresh batch of 50 bonus spins in Book of Dead. That’s 120 freebies for a small effort of setting up and account and making a deposit of at least £20.

Unfortunately, players residing in The United Kingdom, Sweden, Finland, Austria, Norway, Canada, Germany or New Zealand are not able to claim the welcome package. Free spins must be used within 7days; free spins are worth 0.10£ per spin and the maximum winnings from freebie are capped at £100.The deposit bonus has a wagering requirement of 30 times the bonus and deposited amount, and the free spins winnings have the same condition. At the moment of writing, Dunder does not offer any promotional deal, but that happens from time to time.

Deposits and Withdrawals

Each player will see which banking methods are available in his/her country. Dunder accepts payment through Visa, MasterCard, Skrill, Neteller, Euteller, EcoPayz and PaysafeCard. Deposits are processed free of charge and available on the player’s balance in an instant. Most methods allow max deposits up to £5,000. The same options are available for cashing out and these operations are also, in most cases, carried out instantly. Visa withdrawals are an exception, as they can last 1-3 banking days.

Customer Support

At Dunder, they ask the player “How may we help you?” The team is on standby and ready to assist any customer with difficulties. The live chat widget is open every day from 09:00–23:30 GMT for swift communication. Beyond office hours you can always make use of the email service. The help page also covers various burning questions, so it must come in handy when you’re new to the site.
