Stack99 Casino is an online casino that offers downloadable games through the unique Isla Royalty B.V. platform. They are licensed by the jurisdiction of Curacao.


The assortment of slots at Stack99 Casino is hard to find elsewhere. Among the most popular games in their library are Lucky Lady Lea, Lucha Extreme, Studio 69, and Sceptre of Cleo. The themes themselves are quite diverse, but the games also offer substantially different features and paytables to account for every playing style.

Although they are most well-known for their slots, Stack99 Casino also features a fair number of table games. These include both single-hand and multi-hand blackjack, baccarat, and European, French, and American roulette. The collection is not as large as that of larger casinos, but a casual table game player will probably be satisfied.

Video poker players have a total of four denominations to enjoy at Stack99 Casino: Jacks or Better, Joker Poker, Deuces Wild, and Aces & Faces. These games can be played in both a single-hand and multi-hand format, which gives you the power to decide how much variance you want to take on per bet.


Stack99 Casino prides itself on its multilingual support team. In our assessment of their support functionality, we found that Stack99 Casino does a good job at getting players the help they need in a timely manner. For the fastest response time, we recommend using the 24/7 live chat service available through the casino client. Alternatively, use their toll-free German number or tolled international number to speak to someone directly over the phone. You can also send them an email, but responses may take several hours to receive.

Security and Fairness

Stack99 Casino ensures that player details are kept in the strictest of confidence. Most importantly, they use 128-bit SSL encryption whenever you send sensitive information. This technology obscures your data and makes it virtually impossible for any unauthorized person from stealing your details. Additionally, the Stack99 Casino servers are guarded with the latest firewall technology.

Unfortunately, Stack99 Casino has not posted any third-party audits validating the fairness of their games. Considering that their software platform is virtually unheard of, this is not a good thing. Use caution when playing until we gain more information about the Isla Royalty B.V. platform.

I saw that casino offers some no deposit bonus (no deposit money is 10 euro the wagering requirements are 99 times, and the max cash out is 100 euro after 10 euro verifying deposit) so I wanted to grab the chance and I immediately checked the promotions details. On the forum where I found them they only wrote the wagering and max cash out but I didn’t found the excluded countries list so I give a shoot to them and I went to their page to download them casino. They home page is little bit simply, the design is not worst but one thing what I missed is that the live support on their main page. First time I thought they didn’t had live support but after I installed the casino and logged in I found the live operator finally.

I didn’t get the no deposit bonus so I started the conversation with the support, he was a little bit slow, and I waited ten minutes before he arrives. I asked he to credit me with the bonus, after he checks my account he told me Hungarian players are excluded from the no deposit bonuses, I was angry because I registered to them to get this free money, I decided to deposit 10 euro with my neteller but I didn’t want to claim any match bonus so I told him remove all of the deposit bonuses from my account. After it I went to the cashier and made my deposit from 10 euro.

I played with the microgaming slots because I didn’t like their native slots and casino games, I started to play with the thunderstruck II with the minimum 0.3 euro bets. Sadly my money wasn’t enough to make some money and lose it. Sometimes they sent me some special e-mails with no deposit and deposit bonuses but I only can play with my money because the Hungarians are restricted any kind of no deposit bonuses.
Thank you!

Stack99 Casino is something I have come across when finding a no deposit bonus to use up. This nearly took minutes to find but have managed to have a $10 no deposit available to me. When I first found the $10 no deposit bonus this was actually under an affiliate ranked at #145 of their no deposit casinos (Tab). It also looks like this specific casino runs on Oryx Gaming software according to that affiliate which in my opinion is new to me.

When I completed my registration and gotten my $10 no deposit using the code the affiliate has provided me, I went on Stack99's Instant Play Flash Version because having just $10 to play with super crazy wagering requirements did not encourage me to download the full casino. The wagering is set at $10 x 99x = $990 or in other words appear to be the same as AskGamblers. They even have my currency available rather than using an alternative (Euro) which became convenient! Once I clicked on the flash version of the casino I was introduced by different tunes and backgrounds that changed based on the games available. A western theme, a club scene then a mundial game fever theme and so on.

This went on while I was in the casino lobby. My first choice as a game was Studio 69, a 25 paylines club scene that introduced me to it's Seduction bonus game in a matter of spins (7 normal spins to be exact) with 2 coins per line or $0.50 per spin. Inside the feature I had this Heart level/meter for 3 rounds and I was given choices to pick a girl, a drink and a record to play. In order of my choices I succeeded in getting 3 hearts for my first pick on a lady who appeared to be a lonely girl then a red drink (possibly red champagne or a cocktail) which gave me 2 hearts and finally I chose a Sweet 70's record for 3 hearts.

The ending result well, let's just say we hit it off "super well". This gave me $19 with the scatter win for a $21.50 total and also I won 7 Free Spins at 3x! The Free Spins were disappointing as I only got $3.12 from my 7 Free Spins at 3x. But no matter I collected $24.62. Too be honest Studio 69 is a game that reminds me of a NetEnt slot and often every spin I made played a disco dance floor tune (or just a tune) that ended neatly as opposed to other slots where during a normal spin a tune would either not fit or gets cut off or replayed in a messy way. This was actually what made me spin over and over again....at least until winnings gradually turned into a downward spiral. This made me feel as if there is a tall tower (the CN Tower to be specific) and a slide is spiraling around it. Would it be scary to slide down on this at a moderately high speed, going around the tower while under a unimaginable height (Don't look down!)? Remember there are no safety bars or anything to keep yourself secure so the best way to conquer this is to yell out or scream lol. The second trigger made me stop progressing through this feature as the girl I picked wasn't pretty (haha she looked like she was better looking from behind and I had to pick up my mother at the airport as what the bonus told me after it ended lol) and my feature ended with a $1.50 win with 7 Free Spins at 1x and only a total of $4.60. This was of course much worse than my first feature trigger. Right after an unlucky encounter with a lady I moved towards another slot called Anaconda eye where my balance went far (not as far as to withdraw though) but got constricted and swallowed whole by a huge anaconda (under a $0.80 bet per spin and I had to watch my balance suffer! The horror!!! lol)! It made a good enough impression for me to go back but this casino is something I would not avoid in the future.

Somehow it is worth the visit but I know for sure I won't take up bonuses that's for sure. Just all out deposits straight up! A 6.5 out of 10 for Stack99 casino!

The Stack99 Casino has good parts and bad parts. Overall it is a pretty good casino that deserves to spend some time playing here. I take the liberty of giving this advice to players and write this review even though I had the opportunity to
try this casino only playing for virtual money. I found the Stack99 casino from its advertising that he did in its AskGamblers page about a 10 USD no deposit bonus offer that was made also to players from my country, Romania. I immediately registered with them and although this is not a Microgaming casino, I got one of those impossible to remember usernames if it is not written on paper.

Now, regarding the bonus, I nedded to contact the online support and so I learned that the players from my country are ineligible for the no deposit bonus. How much I hate this kind of online support in which a conversation window opens and where the online support can respond or not (and generally does not respond or responds very hard). Of course this is also the case here. You receive the answers after a waiting time of tens of seconds or even minutes. As I said, this is the first casino where I decided to play even if I did not get the no deposit bonus. And this is because the casino itself and the game platform (which is neither Microgaming, nor Rival, not even RTG) are indeed very appealing to the player from the first look. I was playing for virtual money and I can say that I tried about 90% of existing games so I managed to form an opinion about their quality.

As I said the overall quality even exceeds the RTG gaming quality but unfortunately the games are few. About 13 slots (from 5 paylines and up to 25 paylines), 3 types of roulette, 3 card games , 4 videopoker games and as a bonus, a keno game and a game of bingo. As I said, I tried about 90% of these games and what I observed is that there are slots that offer very small winnings and slots wherethe winnings comes one after another. Especially I recommend the slot 'The anaconda eye'where there are separate symbols for bonus game, for free spins and also the wild symbol and where earnings are not small, nor rare. If you like roulette it is worth spending a bit of time at the 3 existing tables if only for their great graphics. Regarding card games their quality is less good and when it comes keno or bingo they are simply a waste of time (as regarding the winnings offered).

So much about this casino. Like I said, though there are few games per ensemble the casino is pretty good.
