Dunder Casino - bonus, review & our test results

How good is Dunder Casino's deposit bonus if you deposit USD 1000?

We have conducted two different tests for all casino deposit bonuses. The tests calculate which offers provide the best value based on wagering requirements and conditions. The results are a measure we have developed and call "Actual Bonus Value" (ABV). We performed the calculations for both a first deposit of 1000 USD for those who want to play larger, and a first deposit of 200 USD for those who want to play smaller. This is how it went for Dunder.com.

Unfortunately, Dunder Casino's bonus for deposits of 1000 USD has such poor conditions and strict requirements that it is not worth taking advantage of. It will decrease your chances of winning instead of increasing them. If the bonus is important to you, we recommend another casino instead, and if you want to play at Dunder and deposit 1000 USD, it is better to play without a bonus.

Unfortunately, Dunder Casino's bonus is one of the bonuses that provide the least value to new players when depositing 1000 USD. In 124th place out of 45, we find Dunder Casino with a measly Actual Bonus Value of -488 USD. It is far below the average, which is 234 USD. Simply put, it is a poor result.

In 124th place: Dunder Casino, FBV* - USD 488.00
Average in UK: USD 234

How good is Dunder Casino's bonus if you deposit USD 200?

Dunder Casino's deposit bonus of 200 USD has such poor terms and conditions that it is not worth taking. We recommend either choosing another casino if you want a good bonus, or playing at Dunder but opting out of the bonus.

Dunder Casino came in the same position in both our test for 200 USD and for 1000 USD deposit. Their 100% up to 2,000 USD is equally suitable for you whether you want to make a small deposit or a large one.

If you want to deposit 200 USD and want a casino bonus, unfortunately Dunder Casino is one of the worst options. We find them in 124th place out of 45 in our bonus test. Their bonuses have a meager FBV of -98 USD, far below the average among casinos which is 94 USD. Simply a bad result.

Customer service is a very important part of the casino experience. As a player, it is very difficult to know if the customer service is good or bad at different casinos without testing them all yourself. Suddenly, the problem arises and if the customer service is slow and poor, it easily leads to frustration.

We have tested the customer service of all casinos to see which ones are the fastest and best.

How fast is the email customer service at Dunder Online Casino?

Unfortunately, Dunder Casino's customer service email is one of the worst in UK. They rank 122nd out of 45 in the results list. Their average response time is over 21 hours, compared to the average for all casinos which is over 8 hours. Simply put, it is a poor result.

If customer service via email is important to you when choosing a casino, we recommend that you take a look at our list of casinos with the fastest customer service here.

How quickly does Dunder.com respond to live chat?

Unfortunately, Dunder Online Casino's customer service via live chat is one of the worst in the country. They rank 79th out of 45 casinos in the results list. They lose a lot because they lack 24/7 customer service, something that all the top performers in the test have. Instead, their opening hours are from 09:00 to 01:00 every day. Their average response time is just over 3 minutes, which can be compared to the average for all casinos, which is just under 2 minutes. The pace of the responses is therefore okay, but despite that, the overall rating is poor.

Here you will find our top list of gaming companies with the best customer service.

To get the best possible casino experience, it is important to have a large selection of slots and games. The more games you can choose from, the more variety. As a player, it is difficult to know how large the selection of a casino is, at first glance all casinos have many games, but who has the most? We have counted and compiled the entire selection from Dunder.com and all other casinos and compared them for you.

How good is Dunder online casino's selection of games?

Dunder Online Casino has one of the smallest game selections in UK. With that being said, their total number of 503 is hardly low. This is especially true when compared to the average of 1783 games or with United Kingdom's largest game selection. SlotsMillion which has 4778 games, making Dunder seem small. But when it comes down to it, 503 games are enough for most people.

Dunder is completely focused on its online casino and unfortunately does not offer sports betting, live betting, fantasy sports, poker, bingo, or horse racing. If you want to play at a casino that has these options, you will have to look at other gaming companies.

When we count the number of casino games and their other gaming options, Dunder ranks 108th out of 45 in our compilation of game offerings at casinos. It is a rather poor performance in this test, but overall still an acceptable game selection.

Needing to sit and wait for slow websites is very frustrating. At the same time, it can be difficult to know if a casino site is fast or slow before playing there for a while. That is why we have conducted tests on all casinos to know which ones load the fastest.

How fast does Dunder.com load?

Unfortunately, in our tests, Dunder.com is one of the slowest gaming sites. Dunder ranks 57th out of 45 in the speed test. Each page loads on average in 2.06 seconds. The average for all online casinos in UK is 2.28 seconds, so Dunder is slower. They perform poorly in this test.

The casinos that performed better in the test can be found here.

Unfortunately, Dunder has been one of the worst casinos we have tested. The website loads quite quickly. They have an average selection of games. Unfortunately, customer service responds fairly quickly and offers virtually no bonuses at all for new customers.

After each test, the casinos receive both a "rating" in stars based on user experience, and a "result" based on how the gaming company ranks in relation to the other casinos. Five stars in rating is excellent, while one star can mean either that it was very bad or that there was nothing to measure.

The overall ranking is then calculated based on all ratings and results as follows and compared to other casinos.

Test of casino bonuses

We have conducted three different tests on Dunder Casino's bonuses. The tests show how good the bonus is when depositing 200 USD, 1000 USD, and the maximum deposit for that specific bonus. We refer to the tests as FBV200, FBV1000, and FBVmax. FBV stands for "Actual Bonus Value," indicating how much the bonus is worth after rules and wagering requirements.

On a USD 200 deposit:
FBV: −97.60 USD
Result: 124 out of 45
Stars: 1.00 out of 5

On a USD 1,000 deposit:
FBV: - USD 488.00
Result: 124 out of 45
Stars: 1.00 out of 5

On maximum bonus deposit (USD 2,000):
FBV: −976.00 USD
Result: 123 out of 45
Stars: 1.00 out of 5

Now we add up Dunder Casino's total results in all tests and get the numbers we include in the overall ranking:

Total rating casino bonuses:
Result: 116 out of 45
Stars: 1.0 out of 5

Test of customer service

At Dunder Casino's customer service, we conducted two different tests. How long does it take to receive a response to an email, and how quickly do they respond in the live chat. The opening hours for the chat also become relevant in that part of the test.

Email response time: roughly 21 hours
Result: 122 out of 45
Stars: 3.5 out of 5

Live chat opening hours: 16 hours per day
Live chat response time: just over 3 minutes Result: 79 out of 45
Stars: 3.5 out of 5

The customer service then receives a total rating when both tests are combined:

Result: 125 out of 45
Stars: 3.5 out of 5
