Dunder Casino Signup Offer – 100% up to €100 + 120 Free Spins

dunder casino welcome promo

New Dunder customers can scoop themselves up to €100 extra to play with thanks to this 100% matched deposit. You can claim it immediately after grabbing the 20 No Deposit Bonus Spins for the Book of Dead Slot. Effectively doubling your money to play with at the casino, taking advantage of this bonus is a great way of starting your Dunder experience and gives you twice the action you’d get normally. Also, you will get another 100 Free Spins, making the total 120. To claim the offer, simply follow the steps above and be mindful of the key terms and conditions which we have stated below.

Key terms:
  • The minimum deposit is €20.
  • The no deposit free spins are issued immediately after creating a new account.
  • The bonus comes with an 30x wagering requirement.
  • Players must meet the wagering requirement within 30 days of the bonus being issued otherwise it will expire.
  • When the bonus is active, the maximum bet is €5 per spin/round.
  • Real money used to trigger the bonus is taken first, before the bond funds themselves.
  • Different games come with different contribution to wagering.
  • The free spins come with a net value of €0.10 each.
  • Offer is valid once per person, computer, IP address or household.

Claim this offer

Welcome bonus suggestion by Country:

Be aware that customers in other locations will receive a different and usually more lucrative welcome package. Players from Finland, for instance, enjoy a matched deposit bonus worth up to €250 plus 120 free spins as well. 20 spins are issued immediately following registration while the remaining 100 are handed out after a qualifying deposit. Bonus terms and conditions do change slightly too, depending on your country of residence. In this instance, the bonus funds and deposit amount have a 30x wagering requirement. For Canada the bonus is 600 CAD & 200 Free Spins so shop around and find the best offer for you depending on where you live.

As Dunder can track your location when entering the site, they will present the welcome offer valid in your region automatically. In all cases, the bonus terms strictly state which country/countries are eligible for the particular promotion.

Other Casino Bonuses

Rather unusually for an online casino, Dunder does not run any kind of bonus on their site other than the one included with their welcome package. This situation could change at any time though so we would advise checking for updates if you are interested in opening an account. The full site is accessible to unregistered users, so it is possible to see all that is on offer before you decide to take the plunge.

The other thing to add is that Dunder will advertise deals via their marketing communications to selected customers. Not everything they offer therefore features on the website and only by receiving these communications can you ensure you won’t miss any promotion that pops up or is specifically targeted at you.

Why you should take these Dunder casino bonus offers

The introductory bonus at Dunder comes with clear terms and conditions and can be completed at a relaxed pace. Not only do customers have 21 days after registering to claim the bonus, but the bonus will remain active for 30 days after issue. You should also find that the funds are ready and waiting in your account immediately after placing your deposit. It is a simple enough offer to redeem and one that does not throw up any nasty surprises.

Is there a Dunder Casino No Deposit Bonus?

If you live in an area where Dunder offers free spins to new customers, you may find that 20 of the spins are issued immediately following registration, no deposit required. The free spins have a value of €0.10 each and must be used on Book of Dead. Any winnings gained from the free spins come with a wagering requirement that needs fulfilling before any money can be withdrawn. When using these no deposit free spins, the most a player can withdraw is €100 – not bad for a no deposit offer.

Mobile Bonus Offer

You cannot claim any kind of exclusive offer just by accessing the mobile version of Dunder’s site. Additionally, as Dunder do not have any kind of Android or iOS app either, no such app bonus exists. While we do very occasionally see casinos advertise promotions specifically for mobile users, we would be extremely surprised to see one here given the lack of bonuses generally. In truth though, given the prevalence and normality of playing on mobile these days, fewer and fewer casinos are offering mobile-specific offers anyway.

That said, players are free to snap up the introductory offer on their smartphone or tablet, but it comes in exactly the same form as on the desktop site.

Payment Methods

As is the case with most international online casinos, the range of payment methods will differ slightly depending on your location. All deposits are free of charge and are processed almost instantly. Withdrawals are free too, but in most cases, you should allow up to 24 hours for a request to be approved.

What is the Dunder casino bonus code?

You do not need a promo code to enjoy Dunder’s new customer offer. To claim it, all you need to do is select the option at the cashier when making your first ever deposit.

Can I claim free spins at Dunder?

Depending on your location, the Dunder welcome offer may or may not include free spins. If this is the case, it will be explicitly stated on the homepage on the site when you first visit. In most cases, the free spins will need to be used on Book of Dead and loading the game will automatically reveal all credited spins.

Can I forfeit a bonus?

Yes, bonuses can be forfeited at any time. If you choose to do this, the bonus amount and any respective winnings will be cancelled. Any bonus will be surrendered automatically if the wagering requirement is not met within the specified time limit.

Do live casino games count towards the wagering requirement of a bonus?

This depends on your location and the type of bonus redeemed.

Will all real money funds be taken before any bonus funds?

No, only the real funds relating to the bonus will be used initially, followed by the bonus. Only once the bonus is exhausted will funds not tied to any bonus be used.

How much wagering is left on my bonus?

If you are using a computer, click your balance in the top menu to track the progress of your active bonus. If you are on mobile, simply tap the wallet symbol instead.

Where are my bonus funds?

If you are not able to see a bonus you have claimed despite placing a qualifying deposit, speak to a member of customer service. In all cases, it is best to rectify the problem before you start placing any bets.

How can I receive information about exclusive offers and promotions?

The easiest way to do this is during the registration process. On the final step, when agreeing to the terms and conditions, Dunder will also ask if you wish to receive information and offers and promotions. Push the slider to the right to give your consent and Dunder will usually send you marketing materials a few times each week.

About the Company

Dunder is operated by MT Secure Trade, a company previously known as Guts Gaming Ltd. In 2012 they became a subsidiary of the Gaming Innovation Group (GiG), a big name in the industry that is listed both on the Oslo Stock Exchange and Nasdaq Stockholm.

Dunder itself was created in March 2016 after a pair of avid Swedish gamblers joined forces. Frustrated by many of the sites they had played at themselves, the duo created Dunder with the aim of it being a fun and trouble-free site to place your bets.

Dunder operates with a valid licence issued by the Malta Gaming Authority (MGA/CRP/257/2014) and the Swedish Gambling Authority (18Li73852).

Customer Support & Contacts

Helpful and committed live chat is available between the hours of 09:00 and 23:30 (GMT – winter, GMT +1, summer). Should you ever run into difficulty with a bonus, this should be your first port of call as most problems are resolved quickly and smoothly.

The alternative option is to send Dunder an email which you can do by writing to help@dunder.com.

One of the answers on the Dunder FAQ pages states that “At Dunder we love bonuses”. Unfortunately, we don’t see that much evidence supporting this assertion. Although they occasionally send certain promotions to selected customers via email or SMS, they do not do much more than this. There are no promotions available to all existing customers and on top of this the welcome bonus is below average.

A simple straight matched deposit up to €100 is very much an industry basic but with the no deposit free spins and the other bonus spins the bonus becomes great. Overall, if you want a casino site that is rich on bonuses and rewards, Dunder is not a place you should be considering. Many other sites we have reviewed are a lot stronger in this area, bursting with bonuses, competitions and loyalty schemes. If you simply want an attractive initial signup offer, however, Dunder becomes a far more viable option.
