What’s New in 4King Slots Casino?


4King Slots is a relatively young casino on the market when it was only established in 2019 and is owned by Mirage Corporation NV. Although relatively new, this casino is able to hold a massive collection of casino games from more than 20 major software providers today.

Besides that, you can also expect excellent bonuses, especially 30 or 60 free spins wager free. However, we also see a few anomalies in this casino, which we advise our readers to consider carefully before making a decision (we will cover in the lower part of the article).

Is 4King Slots Casino trustworthy?

4King slots casino currently holds an operating license issued by Curacao. We do not dare to say for sure about the credibility of this casino at the moment, and it takes a lot of time to give the most unbiased assessment.

Simply because this casino has only been officially open for 2 years, and the Curacao license doesn't say anything about its reputation right now.

In addition, the casino uses VeriSign SSL - Secure Socket Layer technology to encrypt and secure any important customer data. So far, we have not received any reports of data leaks at this casino; of course, you can choose to trust it or choose another casino, which is well proven in terms of reputation.

Mostly Fair Terms & Conditions

To ensure all rights for themselves when participating in 4King Slots casino, players are responsible for following the following notes:

You must be over 18 years of age and above the minimum legal age in the territory where you are located when you use the website.

You must ensure that the place you live is not in one of the countries where the casino is restricted, such as Singapore, Syria, Spain, Taiwan, the Dutch Caribbean Island of Curaçao, Uganda, the United States of America, the United Kingdom, Yemen, Zimbabwe, etc.

However, there are a few things in the casino's rules that we feel will be very detrimental to the players. First, 4King Slots casino prohibits certain forms of betting strategies when playing with bonuses. In addition, the maximum withdrawal is only €1,000 per day and €15,000 per month. Therefore, if the player wins big, it takes quite a long time to withdraw all the winnings.

Website Design & Mobile Compatibility

We are really not happy with the design of the site; it is somewhat outdated and lackluster. However, the large categories are clearly divided to find the services or products they want quickly.

In addition, the design of the website is also optimized for both mobile devices and PCs. Although the look and feel of the mobile site are slightly different from the desktop one, the changes are subtle, and to better suit small screens, it's almost identical to the original site.

9000+ Casino Games


What makes anyone involved in 4King Slots casino surprised is the number of more than 9000 casino games. This is a vast number that few casinos can do, even reputable casinos with a long history.

Players will find many hot hit slots in the casino's library, such as Book of dead, Inca's Treasure, Juicy 7, Mayan Magic Wildfire, Owls Magic. You can find your favorite games by theme, progressive jackpots or video slots, and 3D slots.

In addition, players can also participate in live card tables, where a live dealer will serve them. Naturally, table games lovers will also have hundreds of blackjack, baccarat, roulette options and their variations.

All the games the casino offers come from more than 50 of the most popular software providers today, such as NetEnt, iSoftBet, Evolution Gaming, Pragmatic Play, or Microgaming.

Payment Methods - All You Need to Know


An important note: To ensure that our players always adhere to the Responsible Gaming guidelines, we urge all players to exercise caution when using Visa or any other credit card to deposit money into any online casino that accepts credit cards because you could fall into the credit card debt trap.

There are many payment options that you can choose from to conduct transactions with the casino. Especially crypto-friendly casinos like bitcoin, ETH, USDT, and ripple. Alternatively, you can also use other popular methods like e-wallets like Skrill and EcoPayz or prepaid cards, e.g., Neosurf or Paysafecard, and bank transfer methods like bank transfer instaDebit or iDebit.

Deposit methods

Any deposit transactions will be processed by the casino immediately, except for those made from cryptocurrencies which will be processed within 30 minutes. You can deposit a minimum amount from €20 up to a maximum of €1000 per transaction.

Withdrawal Methods

The casino will process all player withdrawal requests immediately. This is something that everyone wants when joining online gambling sites. To make a withdrawal, a player must deposit and wager 5x Casino and 10x Live Casino. Any no deposit winnings are 50 euros.

However, the maximum withdrawal amount per transaction is €1000 and €15000 per month is quite small. Perhaps because this is a small turnover casino, it cannot accommodate larger withdrawals. If you are not satisfied with this, you can find another grand casino to join.
