Dunder is an online casino founded in 2016 by two Swedish casino connoisseurs, which features games from the most recognized game studios, like Microgaming, NetEnt, Play’nGo, Evolution Gaming, to name a few. Dunder features over 1000 games, focused on slots, blackjack, roulette and live casino games. It’s a simple interface that allows an uncluttered view of the overall casino, helping the user get an easy, straightforward experience with a smart design. 

Dunder Bonus

The bonus is quite large compared to the other casinos, and it also includes many extra spins achievable with a small deposit. Dunder does not have a loyalty program but offers promotions all the time via email or SMS. The site provides a search bar to find games by categories, in case the player has a certain preference.

Welcome Bonus

Dunder offers a generous €600 welcome bonus plus 200 Extra Spins. The whole package can be claimed in four deposits, as follows:

  1. Deposit: 200% bonus up to €50, plus 200 spins exclusively on Starburst (20 daily spins for 10 days).
  2. Deposit: 50% bonus up to €100
  3. Deposit: 25% bonus up to €150
  4. Deposit: 25% bonus up to €300

This bonus breakdown is quite good for the player with a limited budget, as it requires a minimum deposit of €25 to get the first casino deposit bonus and the extra spins. The second bonus requires a deposit of €200, the third bonus requires a deposit of €600, and the last bonus, a deposit of €1200. Overall, to access the whole €600, the player must deposit a total of €2025.
This amount may seem steep, but compared to the welcome bonus, one can hardly find any other similarly generous offer elsewhere. Dunder also has a very simple and transparent wagering policy that even the less experienced players can understand.

Extra Spins

Any player can enjoy 20 Extra Spins immediately upon signing up in the casino, with no deposit required. These extra spins also follow the wagering policy detailed below.

Bonus Code

No bonus codes required Dunder doesn’t use bonus codes. All bonuses are credited automatically after a successful deposit.

Bonus Terms and Conditions

All of Dunder’s bonuses have a wagering required of 25 times the received bonus plus the deposit amount,  same for the extra spins. However, different games have different percentages contributing to the wagering requirements, which can be consulted in their very complete FAQ page.


Dunder has fast withdrawal times, often in 24 hours. It can take as long as 3 banking days depending on the withdrawal method.  As depositing methods, Dunder accepts Visa and Master Card (with a 2,5% fee), Trustly, Skrill, Neteller, Euteller (with a 2,5% fee), EcoPayz, and Paysafe, instant and free of charge. These are the same withdrawal methods, all of them charging a €2.50 fee, except Trustly, which is free of charge. Compared to other casinos, Dunder pay outs are very effective and fast, plus having the advantage of a very reliable 24/7 support system, should any issues arise.

Mobile Casino

Dunder works perfectly on mobile, tablet and computer, despite not having in place a native app of their own. The site’s simple but smart design allows for a smooth navigation and simple access to every game, with the added advantage of the search bar, which makes finding games by category much simpler than other casinos.  It also features a live chat for 24/7 support.

Security and Safety

The casino is licensed in Malta, verified under the Maltese Gaming Authority and ruled under EU legislation. However, for UK players, UK legislation applies. Dunder is a safe casino, where communications are encrypted, protecting the player’s activity and privacy.

Players have to verify their identities when signing up, providing some proof  of documentation as requested by the casino (ID, Bank Statement, Credit Card, etc.)
