  1. "RESOLVED" 4GrinZ Bitcoin Casino owes me 6.775 Bitcoin " RESOLVED"

    I had a complaint with 4GrinZ Bitcoin Casino that happened last Fall. It went on for a while and was RESOLVED. I want to state that complaints can be tough on both the player and the Casino. In this case it nearly cost me loosing an account I held for a year plus a couple really awesome gaming hosts that I not only respect but consider friends.

    I would recommend 4GrinZ Bitcoin Casino to anyone that like to play at a straight forward gaming venue, they pay out fast, their games are top of the line, the have great partners and affiliates and when things get tough and they put their word on the line, they back up what they say 100%.

    Thank you 4GrinZ Bitcoin Casino, Sandy, Lee and Austin for being amongst a very small handful of the most professional gaming operators in the Bitcoin Gaming world.

  2. Enjoying 4grinz casino

    I’ve enjoyed playing a 4grinz casino for some time now. My favorite site feature is the cash back they offer. Its real bitcoin put back in your account every week which you can withdraw immediately or play with. Had some great luck here recently with 0.015 btc cash back which turned into a 1.2 btc withdrawal playing on Slotomon Go. Their live chat team have been friendly, helpful and are always around, which is a big plus and another reason why I enjoy playing here. Keep up the great site 4grinz!

  3. 4grinz has one of the only craps games...

    I have been searching for a bitcoin casino that offered craps and a fast payout. 4grinz offers both. From great customer service reps to diverse game offerings, 4grinz is one of my favorite betting locations.

    However, my favorite part of the platform is that I can place gambling restrictions for daily/weekly amounts, times and other benefits to prevent major loss for gamblers like us. If you like to play craps and to get paid out immediately, then 4grinz is your betting platform.

  4. Great Casino Site with Wonderful Live Support

    4Grinz is a great casino site to play. Although you may not find all the gimmicky bonuses you will find CoinBack and DepositBack, a guaranteed deposit of BTC without wagering requirements each Friday afternoon in your account!! I love this because I know I get to play or withdraw, my choice, each Friday!! The games are fantastic and if you ever an issue, click on Live Chat and the knowledgable support staff is available. I even chat with the managers about promotion ideas and current BTC issues. I have played at most all the BTC casinos at some point, but 4Grinz has become my “Home Casino”. My only complaint is that some times it is difficult to find certain information on the mobile site, but whenever that happens I drop a note in Live Chat and they take a look and make changes if needed. So take the time to visit with Sandy, Lee, Ralph, Fred, and Bookie to learn about all 4Grinz has to offer, I know I am glad I did.

  5. 4grinz is rising ........

    I’ve been playing at 4grinz casino since they just started, they have grew much stronger than ever now…… with new games and bonuses and spins…… they have branch out like I knew they would….. a lot of the games you can hit big with bonuses, you have there friendly support, who always care enough to chat with you when you need them too…… I personally love how they have change for the better, and hope they continue to grow even stronger…….
