    Well I found a No Deposit Bonus of $30 for new players NDN30DUKES and this one actuallly worked with no problems...I will let you know how I do.

  • United States itsallboutheride


    Well I played with this bonus for 3 days and had a blast...,I only played the minimum, but it was great playback...I played for approx 40 hrs total...the customer service were very nice.

    It's annoying having live chat right next to the game screen and having the representatives talking to you when playing. Every time a deposit is made, a bonus is automatically credited to your account. Might be great for some, but I don't play with bonuses and I have to ask each time to have it removed. It does take some time for them to answer this request :(

    I enjoyed this site, but I typically tend to prefer sites that have instant flash players and this one does not. However, I was still pretty happy with it. I originally joined for the no deposit bonus, and I actually received £20. I was very pleased with their slots! It's one of the first things I check out when I want to join a new site, but they also have tons of other great casino games to play. I really liked their Black Diamond slot. I had never played it before but I was happy to give it a try. I found the jackpot to be well worth it and the graphics to be nice as well. They have some pretty low bets also. The atmosphere is friendly and I have enjoyed making friends since I began playing here. The customer support is helpful as well. Overall, no complaints!

    As a Top Games site, I wasn't all that familiar with the games and graphics. The site doesn't look all that fantastic to me to start with, and I think they should definitely improve or just modernize the whole thing. OK, it's not all that bad (I have seen far worse) but i believe it should look better.
    I wasn't much happy to have to download and install the software to my computer, and still prefer clear Instant (Flash) casinos.
    They have a rather standard offer for the games, and I have spent my time divided between the slots and Keno, because I always wanted to give it a try. Not too much luck so far, but I did make some money I transferred. Contacted the support, followed their instructions and there you go!
    I like the fact it is opened for US players, and the only thing I wish was a little more substantial Bonus and better promotions.

    This site starts you off with a very nice welcome offer. The registration process is simple and as soon as you sign up, your account will be credited with $15 free. In addition to this nice little bonus, you will also receive various deposit bonuses. On your first deposit, they will give you a generous 350% bonus, up to a $1,000 max deposit. On your second deposit, you will receive a 250% bonus as well as a 200% bonus on your third deposit. On top of all this great stuff, you will also automatically be enrolled in a new members' raffle upon your first deposit. This exciting raffle features one $500 and two $250 cash prizes.

    They site is easy to navigate and I enjoy the selection of games they have to offer. They have plenty of slots and other casino games up for grabs. Favorites like roulette and blackjack are available and there are awesome jackpots available!

    21dukes casino using top game software. which is one of the hardest software to win on. that is my opinion. i have only made one deposit here at this casino. when i first signed up i was given a no deposit bonus. later i decided i wanted to deposit cause they offered my a really good deposit bonus. i like it was like 500% or 600%. which is a really good bonus. normally i read the rules of the casinos but i did not here until after i made a deposit. the playthur on my deposit and bonus was 99times. which is a really high playthur. it really did not matter cause i never won anything big or even build up my balance. so i have never cashout here. I really enjoy there games , they are fun to play and the graphics are really good. i just think the games do not pay very good they seem to me just eat your money. i do not think that i will ever make another deposit here cause i can not win at there slots. as for the casino live help is very nice. i've been to them a couple of times and was given a free money bonus. the live help is located right next to your slot. so you can spin and talk at same time. it has been a while since i made my deposit here but every once in a while i still get emails from the casino saying that they have put money in my account. i did check my account a while back and had around $40 in it. this was after i recieved several emails. so i guess it just built up. i have not checked it in a while to see if any more is there but they seem to be a very generous casino. it may just be me and top game software do not go together as to why i do not ever win. i have heard of others winning so it just might be me. the minimum to deposit is $25 and with a 500% match deposit bonus that gives you $150 to play with . which is really good. just make sure that you go to live help before you make a deposit so you can get the bonus after you make your deposit.

    I think this is my first Top Game casino where i have register. I receive 20€ when i finish the registering form and they require to fill your profile for add the bonus. In this years i have read that Top Game Casinos have not really good reputation. Unfortunately i don't have experience with deposit and withdrawal with this group, but i don't really like the software, i prefer Microgaming or Playtech of course. A few things that i like is : they are generously because very often they treat you with a frebbie and i think it's okay for try the games, infact they have a very good range of slots machine! My favourite is " Forest of Treasure " i really like it, but it doesnt pay very well. For those who don't like slots there are many games like roulette, blackjack, video poker.. The T&C's i think are not really good because for the no deposit bonus the wagering requirements are 99x plus the deposit you have to do for withdraw your winnings, that's why i have not yet deposit here. The support is really nice and kindly, they reply you in 2 minute with the live chat instead of the software, but trough email is really hard to receive a fast reply. They have an high match bonus if you want to deposit, 500% is a massive bonus and i think that i not seen in any of the casinos i have played before. 21Dukes Casinò offer the major security for the player with the SSL encryption so if the site crash or lose connection you can't lose your money. The language of this casino is only in English and the currency is in $. They have various deposit methods such: Click2Pay, EcoCard, MasterCard, Visa and Neteller, is online since 2008 and have the license in Costa Rica. The withdrawals methods are Bank Wire, Cheque, Skrill and Neteller and they have a 2500$ limit per week for withdraw. They assure pending time of 4-5 days, but i read that in the meantime they try to stolen your money from the withdraw so you can lose it and they don't pay you! My final vote is 4/10.

    Played here only with no deposit bonus. Very enoying online chat, constantly offering deposit bonuses

  • Bulgaria MerengueBG


    Typical casino software made ​​for one purpose and that is to rob American players taking advantage of the ridiculous ban on online gambling to the U.S. government. This applies largely to Rtg and Betonsoft casinos. I hope that one day the ban will be eliminated and American players will again be able to take advantage of the best casinos on the net. My personal experience with this casino is small. Only a few NDB's some time ago, when they still allows players from Bulgaria.

  • Macedonia helena_kp


    Top Game casinos,well honestly I dont like theirs games ,but when it comes to fee chip ,why not.I did try theirs games few months ago,when they were having 20 $ free chip,when you joined theirs casino,well I think that they have the same promo still.My playtime there finished very fast ,as I said dont like top games and honestly I dont trust top games casinos.

  • United States deb66


    i like playing topgame casinos but my only complaint with 21Dukes is they put restrictions on what games you can play with free bonus money. I like to play keno and it is not allowed.

  • United States helpmenow0031


    I just think that if you are going to offer a free bonus it should be cashable. I don't like when they call me and give me a chip that is not cashable, no point.

  • Canada Gloriabe


    I received the no deposit bonuses and played with them, I like the newer Topgame games they brought in, this has kept me playing here sometimes, I did win off a no deposit bonus from a Topgame casino once but did not withdraw it soon enough and they took it out of my account, that was my mistake though, I have found that some of the chat operators are too pushy to get you to deposit, but not all of them,

    I do like the newer games though, some of them,


  • United States amillerasu


    Very good casino. after registering, My account was credited with $15. At one time I was over $100 in my account and played for 4 days. the slots are a lot of fun. I recamend this casino to everyone.

  • Canada JamilKarim1234


    Pretty good casino. All the bonuses were paid out right away and I had no issues with withdrawals.

    Topgame Casinos are generally pretty good especially for table games and 21Dukes is no different. I didn't enjoy the slot games here but I generally use RTG for that anyway so it wasn't a big deal.

    Customer Service Reps have def gotten better over time here. At first they seemed like they didn't know what they were doing but over the past year they've made a huge improvement here.

    Overall I'd say its a 3/5

  • United States CASINOMANIAC101


    Not one of my favorite casinos at all, the customer service is poor and they are slow to respond to the customer. Also don't like that they have no tournaments here. I give this casino a 2 star rating.

  • United States tinker


    At one time I mainly played Topgame Casinos because I enjoyed their games and seem to have quite a bit of luck overall. This particular casino I've deposited well over a dozen times and I can say today that they will never see another dime from me again. First of all, I never take their deposit bonuses and every time I would make a deposit support would pop up and be pretty insistent that I take a bonus. Secondly, once when I tried to make a withdrawal it was a nightmare. I was locked out of my casino account without any explanation with a withdrawal still pending. Needless to say I never received a dime from them only the run around. BEWARE

  • India jingdrag


    21 dukes is one of few topgame casino i feel you can trust on, although i havent cashed out from this casino , but i havent read many payout complaints for this casino, like all top game casino their wagering rqrmnts are too high if you claim a no depsoit bonus , its hard cashout with no depsoit bonuses on top game casino, because they require you to wager 100 into the bonus you claim.

  • Sweden piffen


    Ok, this is a Top Game casino. Listen: Principally all TG powered casinos have a common black list where they can see if you have other TG accounts and have played bonuses and won. If they are just a little bit nervous for you they will block your account. Yes, I used the no deposit bonus and hit a big win so that I would be able to cash out, but just a few minutes after that hit they blocked my account. If you are at their black list you should never use any deposit bonus, because they might confiscate your money.
