The Expert's Opinion:
A brand new player in the online casino market launching in March 2016, Dunder Casino comes from a good pedigree being managed by the same operators as Casumo. It boasts an outstanding selection of online slots from a variety of developers both old and new in the business, offering slots players a comprehensive gaming experience. Operating out of Malta, Dunder (meaning Thunder in Swedish) has created a very contemporary online gaming experience. For more information read our detailed Dunder casino review below. Ready to play?

Welcome Bonus

The Dunder Casino welcome bonus consists of deposit matches worth up to $600 + 200 free spins:

No Deposit Free SpinsFirst DepositSecond DepositThird Deposit
✓ 20 Free Spins on Starburst
✓ Receive a 200% match bonus up to $50 + 180 free spins
✓ Receive a 50% match bonus up to $150
✓ Receive a 25% match bonus up to $400

Sign Up 100% up to C$ 50 + 50 Spins WR: 30x(B+D)


Required Deposit:In order to unlock the full $600 sign-up bonus, new players need to deposit $1925 and this will grow your bankroll to $2525, which represents an overall deposit match of 31%

Small print:Wagering requirements of x 25 bonus + deposit on the match bonus and x 25 wagering on winnings from the free spins. 30 days to meet the wagering across all 3 bonuses before they disappear.

To clear the bonus Dunder requires play-through requirements of x 25 bonus + deposit. Slots games count towards 100% of these play-through requirements, table games 10% with video poker games not making any contribution. 

Bonus in practice: As soon as you sign up without having to make a deposit you get 20 free spins on Starburst. On your first deposit whatever you deposit Dunder will double up to $50, so if you deposit $20 they will match this with $40. With the wagering requirements of x 25 bonus + deposit, a $20 deposit will need wagering of $1500 (25 x $60 ($20 deposit + $40 bonus) in order for the bonus to be unblocked. Your first deposit also unlocks a further 180 free spins on Starburst over 9 days. The 2nd deposit is a 50% match so if you deposit $100 Dunder matches this with $50. Finally on the 3rd stage match Dunder gives back 1/4 of what you deposit, so a $200 deposit as an example is matched back with $50.

Bonus Sum Up: There are pros and cons to the Dunder introductory bonus. On the plus side we like the 200 free spins with a good x 25 wagering on any winnings. The 200% match on your first deposit is also a good starter, a nice way to ease you into playing. On the downside wagering on both bonus + deposit increases your overall wagering demands – we prefer higher wagering on just the bonus,  whilst the overall match of 31% is lower than you can find at other casinos we recommend here.

Mobile Casino

Dunder Casino is typical of the new generation of online casinos in that all games are played in Flash mode, and so the mobile casino is essentially a mobile-optimised version of the main site. Mobile slots can be played directly in the browser of any mobile device, including smartphones and tablets using iOS and Android operating systems.

What this means for you is that you get the same gaming experience in terms of games and their organisation, as well as managing your account, banking, security and customer support. Also, like the main site, the mobile casino is well laid out and easy to navigate, while the game icons are clear and easy to read, making finding your favourite mobile slots very easy.

The mobile casino features one of the largest collection of mobile slots available:

  • Classic 3 reel slots, such as Ace of Spades, Break da Bank, Retro Reels
  • TV, movie and superhero themed slots, such as Tomb Raider: Secret of the Sword, Hellboy, Bridesmaids, Game of Thrones (243 ways to win and pay lines), South Park, Aliens (NetEnt slots), Wonder Woman, Green Lantern (Amaya)
  • Classic video slots, such as Bullseye, Karate Pig, The Finer Reels of Life, Agent Jane Blonde, Kathmandu (Microgaming), Alien Robots, Dazzle Me, Spinata Grande (NetEnt), Wizard of Gems, Eye of the Kraken (Play n Go), Sinbad (Quickspin), Boomanji, Aztec Treasures (BetSoft), Enchanted Meadow (Play N’ Go)
  • a full range of the biggest and best progressive jackpot slots, including Major Millions, Tunzamunni (Microgaming), Geisha Wonders, Super Lucky Frog (NetEnt), A Night in Paris, The True Sheriff, Diamond, Mr Vegas (BetSoft)

The mobile casino also offers the same range of Live Casino and table games.


Dunder is yet to establish an ongoing series of promotions for regular players or to get its VIP programme up and running. However, future bonus offers and other promotions will be sent to players via email and SMS.

Bottom Line on Dunder

Being a newly launched casino Dunder still has a bit of work to do, namely to organize more banking and support options and to get its promotion and VIP program launched. Still, the foundations of a strong casino is in place including a stellar slots selection and a tempting 200 free spins promotion for new players. You certainly won’t be a ‘Dunderhead’ for giving this site a try.

I made a deposit for 400$, and the site timed out, the deposit has been lost for more than 24hours, and they still haven’t resolved the issue. Really scary to think they can’t loose your money like this.
