Koi Casino Review

After a detailed look at Koi Casino, our casino review team has the full picture. We used our casino review process to look at what it does well and what it could do better. Putting the casino through its paces, our team reviewed its Terms and Conditions, licenses, player complaints, support, and limits. This gave them what they needed to work out if this casino is safe and fair, one to avoid, or falling between the two.

We used our team's findings to work out the casino's Safety Index. This score measures the safety and fairness of online casinos. The higher the Safety Index, the more likely you are to play and receive your winnings without any issues. Koi Casino scored a High Safety Index of 8.4, which is why it could be considered a favorable option for most players in terms of fairness and safety. Keep reading our Koi Casino review to learn more about this casino and decide whether it is a good choice for you.

Safety Index – Koi Casino fairness and safety

We measure a casino's Safety Index by employing a multifaceted formula that takes into the account an abundance of information collected and evaluated in our complex review. These consist of the estimated size of the casino, its T&Cs, complaints from the players, blacklists, and many others.

In our Koi Casino review, we carefully went through and inspected the Terms and Conditions of Koi Casino. We came across some rules or clauses that we did not appreciate, and all in all, we find the T&Cs to be somewhat unfair. Unfair or predatory rules have the potential to be held against players to defend withholding their winnings. Therefore, based on our findings, we advise caution if you choose to play at this casino.

Koi Casino is a big online casino based on our estimates or collected information. This casino has a very low value of denied payouts in player complaints with respect to its size (or it hasn't had any complaints). In our evaluation, we factor in both the casinos' size and player complaints, recognizing that larger casinos, having more players, often face a higher number of complaints.

Based on our findings, no important casino blacklists feature Koi Casino. In case a casino is featured on a blacklist, including our own Casino Guru blacklist, it's likely that the casino has committed wrongdoings towards its customers. Thus, we encourage players to bear this in mind when deciding on which online casino to play at.

Taking into account all factors in our review, Koi Casino has scored a Safety Index of 8.4, representing a High value. For most players seeking an online casino that prioritizes fairness in the online gambling experience they offer, this casino is a recommendable choice.

Note: As far as we are concerned, Koi Casino is related to 4 different casinos. Because of the relationship between these casinos, we have considered the qualities of the related casinos when calculating the Safety Index of Koi Casino. They had a positive effect.

Terms and Conditions of Koi Casino

Whenever we assess online casinos, we thoroughly examine each casino's Terms and Conditions to determine their level of fairness. Many of them have T&Cs that contain rules and clauses that we view as unfair or plain predatory, since they can be held against players as a basis for withholding their winnings in certain circumstances.

We found some questionable rules or clauses during our review, because of which we consider the Terms and Conditions of Koi Casino to be somewhat unfair.

Note: Our particular discoveries from the T&Cs analysis are available here.

Player complaints regarding Koi Casino

Player complaints are a crucial component of our casino review process since they provide us with a clear understanding of difficulties faced by players and the way that casinos deal with them. We examine all complaints submitted through our Complaint Resolution Center, and also those we collect from other sources when calculating each casino's Safety Index.

We have found no relevant complaints about this casino.

User feedback and reviews of Koi Casino

Casino Guru allows users to review and rate online casinos to share their experiences, views, and feedback. These allow us to calculate a general user feedback score that falls between Terrible and Excellent.

Based on the 7 user reviews of Koi Casino in our database, it has a Mixed User feedback score. The reviews are available on this page in the User reviews section.

Note: Remember that user reviews might not be the most accurate representation of the casino's quality. There have been cases of casinos writing fake reviews to improve their user feedback score. Alternatively, there have also been cases of dissatisfied players who left multiple negative reviews to damage the casino's reputation. We do our best to filter these out and calculate a representative user feedback score; however, just to be safe, we do not include user feedback in our Safety Index calculation.

Licenses and company information

Koi Casino is owned by Njord Ventures B.V., and we have estimated its yearly revenues to be greater than $1,000,000. This makes it a small to medium-sized online casino on our scale.

Payment options, withdrawal limits and win limits

Koi Casino supports 5 deposit methods. This includes: Mastercard, VISA, Online bank transfer, Brite, Revolut.

Many online casinos have set limits on how much money players may win or withdraw. Some casinos apply win or withdrawal limits that can be rather restrictive, but usually these limits are high enough to not affect most players. This is why we always acknowledge these when assessing casinos. All the details regarding the casino's winning and withdrawal limits can be found in the table below.

Koi Casino bonus offers and codes

Online casinos offer bonuses to new or existing players to give them an incentive to create an account and start playing. No deposit bonuses, free spins, and deposit bonuses are some of the most sough-after bonus types. No deposit bonuses can be obtained by registering an account at the casino, while deposit bonuses are given out upon making a deposit. Moreover, casino promotions can also include bonus codes, welcome sign-up bonuses, or loyalty programs.

Unfortunately, we currently do not have any bonus offers from Koi Casino in our database.

Please keep in mind that these bonuses might not be available to players from certain regions. See the 'Bonuses' section of this review for more details and to find out which offers are available to you.

Safety and fairness

Take a look at the explanation of factors that we consider when calculating the Safety Index rating of Koi Casino. The Safety Index is the main metric we use to describe the trustworthiness, fairness, and quality of all online casinos in our database.

Terms and conditions
Somewhat unfair
Issues found: 3
Last updatedLast updated
Show detailed analysis

We go over the terms and conditions of each casino and look for unfair rules that could potentially be used against players. Any clauses we consider to be unfair result in a lower Safety Index for the casino.

Casino size
Medium casinoBig group

Bigger casinos are generally safer for players, because their high revenues allow them to pay out even very big wins without any issues and their quality has been proven by a large number of players. We take into account estimated revenues over the last 4 years and also consider revenues of related casinos.

Complaints ratio
Very good
Total complaints: 3
Last updatedLast updated
  • Opened 0
  • Unresolved 0
  • Resolved 1
  • Rejected 2
Browse complaints

Player complaints signify that the casino does not treat players right or deal with certain situations correctly. We consider the number and seriousness of complaints in relation to the casino’s size, as it can be expected that sites with more players will also have more complaints.

Blacklists
None
0x

    If a casino appears on relevant blacklists, it is usually a sign that it has some negative qualities. We consider each blacklist and decrease the casino’s Safety Index based on our view of the situation and its seriousness.

    Other factors
    Neutral

      There can also be other characteristics and qualities of a casino that influence its Safety Index, such as win limits, low withdrawal limits, fake games or licenses, bad or no customer support, a network of land-based shops, etc.

      the return percentages of this casino are really low. I have played in many casinos the same games as in this casino. rtp on average only 30 percent. so beware of this casino. the Estonian license does not guarantee honesty. monitoring is non-existent. every time you play, there is some evidence against the casino.
      • rtp low in games
      • discharge takes hours

      Hi Pasi,

      Thank you for the feedback provided,

      Kindly note that all our games are all coming from verified and trusted gameproviders, such as NetEnt, Pragmatic Play, and others, none of them provide games with RTP 30%, and we would in any case not even consider offering such here at KoiCasino, as we wish to see and provide fair and square entertainment for all our players.

      We are fully licensed and legitimate online casino, and all return-to-player percentages can always be seen in-game via info, where provided by trusted gameproviders.

      Kindly also note that RTP is calculated from millions of game rounds and is therefore not proportional to the rounds played by a single player.

      Should you have any questions regarding this, or other matters, do not hesitate to get in touch with our friendly customer support via our livechat available 24/7 in multiple languages, as well as via support@koicasino.com email address.

      Wishing you a lovely day and good luck with the games!

      Koi Casino
      Hi Reio,

      Thank you for the feedback provided,

      We are sorry to hear cashback has not been up to your expectations.
      Please note that whilst we do have x10 wagering on cashback, it is very small and easy for player to complete, this is amongst others to prevent fraudulent activity.
      Also please note that we payout cashback daily, not weekly as majority of online casinos. This means that should you win big, the upcoming days your cashback will be credited as usual, not next week where your winnings would be deducted from total cashback amount. We also pay cashback to our winners the next day in form of free spins!

      Should you have any questions regarding the cashback or other matters, you are always welcome to contact our customer support at support@koicasino.com that is available 24/7 in multiple languages.

      The long processing time takes place at the Moth Casino
      Koi Casino
      Hi Eetu!

      Thank you for asking! I answered on that side of the discussion, but I'll post it here.
      For transfers made via the online bank, it only takes a few minutes for the transfer to appear in your own account. KoiCasino aims to accept withdrawals within about 4 hours after submitting a withdrawal request. Of course, this can vary from time to time. And possible changes of payment intermediary can affect processing times and transfer times.

      The worst casino ever € 100 must be at least that you can withdraw money, it can take several days to withdraw
      Koi Casino
      Hi ItsAkitza!

      Thank you for your feedback! We are sorry to hear that you had a negative experience at our casino. We understand that long withdrawal times are frustrating and thus KoiCasino usually processes withdrawals within a few minutes.

      The minimum withdrawal amount has decreased since your experience, and nowadays the minimum amount is 20 euros.

      If you have any questions, you are always welcome to contact our customer service at support@koicasino.com, which is available 24/7 every day of the year.

      Basic Curacao casino which delays withdrawals ... There really is no pay and play casino and no withdrawals come in 15min because the processing time is reportedly not even defined and they are handled manually.
      • Very slow housings
      Koi Casino
      Hi Hamsivi,

      Thank you for your feedback,

      In no case do we delay withdrawals, but we naturally process everything as quickly as possible to the player's account.
      In some cases, such as for big wins, the game rounds may be checked with the game provider to prevent dishonest activity. This is normal practice in all casinos.
      Withdrawals are processed very quickly, and on average the player sees the funds in less than 15 minutes, almost always immediately.

      Please also note that we no longer operate under a Curacao license, but under a more regulated and more reliable gaming license issued by the Estonian Customs Board.

      If you have any questions regarding this or other matters, you can always contact our customer service, which serves you 24 hours a day, every day of the week.

      Have a fun day!
