Nothing positive! when the question have been asked you will never get direct answer.... all is on technical problems.
The most dishonest casino in my opinion! They send promotions by mail which doesnt exist! They change loyality point system whenever they want! Always when have "technical problems" live support is not available...They come only when all changes and THEIR problems are solved! Keep away.
Probably the worst place ever! I made a deposit and 100% was not added..... Chat is almost never available! Have to sit minimum 20 min and then maybe someone will assist you! Very bad experience.....

Nice selection of games, but nothing special. At least the software seems not to cheat.
They make a lot of advertising with their special VIP treatment, but I never met a person online or real live who actually managed to get a VIP here. I wagered for almost 500k € in the last 3 months and I asked several times when I will become a VIP player and they just give me answers like "when you are VIP you will know". I am used to get a very special treatment in online and offline casinos for my high wagering (I sometimes get helitaxi to the Casino for free!) and here I am treated like shit. Also they tell me to withdraw via Neteller I can try but its not guaranteed. They then just send my withdrawal to my bank account without further notice. This happened 4 times already even when I complained each time.
Hello Sandrassss,
We do appreciate you for choosing our casino and we would like to keep you as a happy customer of Casino Sieger.

Casino Sieger is one of the best casinos I have ever played. It offers great games like Starburst and Twins Spin which are my favourite ones. Also what I really like about this casino is that you can make quick deposits with a variety of methods and it is done fast.

But the best thing is the speed of the payout and how easy they made it for players to make a payout, and for me that is the reason I decided to play with them.

Casino Sieger is a casino I joined a long time ago. It belongs to the Condor Gaming group of casinos along with Rembrant and B-Bets casino. I have accounts in all three casinos from this group and I think they are a safe group of casinos to play in.

Imade an account here but made my first deposit in the casino was a few months later. In the meantime I got a few promos from this casino for some free spins which I gladly took. The main reason why I didn’t make a deposit right after I made an account here was because their welcome bonus wasn’t too attractive to me. This casino offers a 100% match deposit bonus with a pretty high wager of 60 x bonus. Every experienced gambler will agree with me that this isn't a very attractive offer. It would be much better if the bonus has a 40x bonus wager like in a lot of other casinos throughout the industry. Still like I said after receiving several free spins promos it seemed fair that I make a deposit and try my luck in the casino. I made a small 20 euros deposit via Neteller and another 20 euros were instantly added to my account.

This casino offers only instant play. The navigation through the site is pretty easy and you can check your progress through the wager at any time so there is really no need to contact live chat support, but they are online and ready most of the day. The casino has a nice selection of Netent, Microgaming and Betsoft slots.

With my balance I started playing Immortal Romance. I had some nice wins and raised my balance up to 70 euros. After I lost 10 euros I decided to try a few of my favorite Netent slots but didn’t have any luck in hitting big and finishing my wager.

Unfortunately I didn’t manage to make a withdrawal here so I can't speak about the payout timeframe but I hope that will change in the future. Overall this is a descent casino to play in and I recommend it to everyone.
High welcome bonus wager of 60 x bonus.
Live chat not available 24/7.
Above all thank you very much for leaving your feedback about our casino. We find it very positive and also hear you well about the improvements we should perform. Your opinion matters very much to us and we are glad you find Sieger a trustfully environment that provides enjoyable play.

One thing you addressed is our Live Chat opening hours. You might be interested to learn we will have far wider opening hours in the very near future, this will suit your needs :)

We have also read your feedback on the wagering requirements, but let me give you quickly some positive inside:

It indeed may seem that wagering requirements of 30 times deposit and bonus amount are high; but what we have, and most other casinos don't, is a buy off option. This means you can use this option at any time to request a payout, even if your bonus requirements have not been met completely. More about buy off you can find on Sieger's bonus terms page, but in short, if you for example fulfill only 70% of your requirements you will be able to payout 70% of your winnings.

I honestly wish that, upon your next deposit, with which you may use your 50% bonus up to 200 eur, you will strike big winnings and withdraw them :) When that moment comes, we're also counting on your honest feedback regarding our withdrawals.

One more time, thank you for your effort in leaving this feedback, continue enjoying your time in our casino and good luck in your future play!

Honestly. As honest as I can be, absolutely nothing.
This place is one of the worst dishonest casinos around. No doubt.
I rank them below Video and even 32 red.
This place does not give the promised bonus and they don't even respond to the complaint made on here!

They gave me my scratch cards free spins after three days of emailing them. Ridiculous.
The free spins, 50 on twin spin paid a total of .60 cents! Lol

Do not play here. No way. Their mobile platform is a joke.

They are dishonest. They lie and they respond to emails in 24 hours? And don't even address the main issue. All they say is that "the relevant department crap"

Do not play here, watch out!
And forget the 31% RTP on the 100 deposit.
This casino is licensed in Costa Rica and has a couple of important games providers like NetEnt and Microgaming, this being the main reason that attracted me and made me to create an account here and to try my luck!

I saw on AskGamblers that they have a nice welcome bonus,100% up to 200 euro + 20 free spins on Wonky Wabbits slot from NetEnt!

I created my account and I went to cashier to make my deposit but it was a problem because the minimum deposit amount is 20 euro and I was planning to deposit only 10 euro!I decided to deposit 20 euro and to try my luck!

The website looks very good and interesting and they have all the information that you need!
With 2400 euro to wager, I decided to open Silent Run slot, a game that is paying good in my opinion! I didn’t wanted to play Microgaming games because I was a little bit disappointed last time when I played!

The first spins paid well, but it was a period when my account balance kept decreasing and I decided to change the game and to play Wild Water slot!
But 2400 euro was much money to wager and finally I lost them and obviously I was upset! I played the 20 free spins, I won only 7.5 euro from this free spins, there was no wagering requirements but I wasn’t able to withdraw this small sum and I kept playing this slot and 5 minutes later lost them!

I will give a 9 for the games because I like Netent and Microgaming games, quality slots with a decent payout rate!
The payment methods will receive an 8 and the support team a 9 because they have live chat and its important to me!
I didn’t paid attention to the wagering requirements and was a mistake because this bonus has 60 x wagering requirements,very high in my opinion and I don’t think that many people will be attracted by such a poor bonus even if it is 100% and has free spins,so I will give a 6!

The reason why I recently joined casino sieger was because of its providers. It's based on a few of my favorite softwares, such as Evolution gaming, Netent, Microgaming and Betsoft as well.
I really liked the look of this casino and I decided to try it with a 40€ deposit.

I started to play live casino holdem, and I spent some quality time there because it's my favorite casino game and I love playing with such professional and well spoken live dealers. I think if a casino provides live games, than they have to be in good quality like in Sieger casino, otherwise they shouldn't even be at all. I placed 1€ to 1.5€ bets and after some time my balance went up to 80€.

After that I visited my best friend Starburst. I placed 2€ bets and after few empty spins got something good out of - 7€. I was quite lucky and when the wild symbols came, they turned my 2€ bet into a 15€ win. However, the empty spins between the wins were quite enough so the winnings only covered the loss. Even though I love the design of this game, lately, it pays me pretty bad.

After that I played Slotfather, a 30 payline slot game, for some time. I placed 0.60€ bets per spin and somehow I couldn't get more than 1.80€ win within 20 spins, so I switched to Attraction slot. I just love the design and color scheme NetEnt games has! You can always notice NetEnt games between others, at least I can. So I played it with 0.40€ bets per spin but I wasn't really lucky there and after a while quit it while I still got more than 60€ left. At last I visited live casino again, played some live baccarat hands for a little and with 80€ in my account requested a withdrawal.

Overall, I recommend this casino to other gamblers, because I had a great time there. The variety and quality of games and live casino is great, the withdrawal took less than three days. I guess for full happiness I would like to see Marvel games there, then this would be my number 1 casino! But seriously talking, I'm sure I will deposit there again and try their bonuses.
This is sister of Rembrandt casino, and they pretty same. Casino Sieger offers to players games from Netent, Microgaming, Betsoft and few others which I have never played in my life ;D but just did not notice that, and of course this means that this is not interesting slots for me.

As an lover of Microgaming and Net Entertainment games, of course I was happy to make my first deposit in casino Sieger, and casino was happy to credit me 100 % bonus, or not happy, who knows, but the fact is that I got bonus without any problems, and was able to start my adventure.

This day I decided that this will be NetEnt adventure, I started from Alien robots video slot, you know, I am describe this slot a lot in my review of this game (yeah, on AskGamlers you can read review of slots too, surprised? Hope so ). Then after freespins I obviously was happy to open Gonzos quest, oh god, I like this slot a lot, it is always a lot of fun to play it, and moreover this slot can pay a lot of money, but sometimes this bastard just stole my money :D

After some playing, I lost 50 % of my balance, and with bad feelings open Evolution. You know, on slots like Evolution you can wait feature at average every 100 spin... But i get in terrible, awful run, and did not saw freespins for ~ 400 spins, and get busted.

So, as you see I did not managed to get withdrawal from casino Sieger, and from their sister Rembrandt casino, so I can not judge them seriously, good this casino or safe. But I like it, and it is shame they does not send out to me any nice bonuses.

Sieger Casino which has Netent Gaming platform, Betsoft Gaming, Evolution Gaming and Espresso Gaming .
I did sign up just because i got 5 euro free chip from them as a welcome offer and if you decide to make a deposit they will give you 100% match bonus on your deposit.

I never deposited here like I explain in the other review of Rembrandt Casino, which I think that they are sister casinos under Costa Rica licence.
Well for the time being I only trust Malta licencing or if they are under Malta jurisdiction.
So from them from time to time I am getting free spins, but i never won more then 050 to 0.60 euros from the free spins.

But today I got 2.98 euros from Sieger Casino.
I played for a while but first I played Fruit Case slot which it was getting me nice winnings, but its really funny how today the slots I played on both casinos payed the same .
Starburst I can tell you it was giving me the same money like in Rembrandt Casino or it was just coincidence.

I played the same slots on both casinos like Gonzos Quest, Starburst but here I played Fruit Case, which in this moment its number 1 my favorite game. In 1 of the casino I did hit 100 euros from 1 spin and the bet was 0.40 euros,well that' a good game or good luck I had that day.

So about this Sieger Casino I don't see any reviews so I have to wait till I read or find out something more about them, especially about cashing out from them, how fast are they etc.
I like both of this casinos because they have good bonuses, NetEnt games but like I said I will wait.
