Cryptowheel.net
This is the best selection of gambling games available for the currencies you've mined or come across! On the main page you can choose to play multiple different kinds of games for multiple currencies (DGC, USDe, ARG, GPL, Coino, CSC). All of the games are "provably fair" which means that all the rolls, spins or whatever kind of mechanic that's being used can be completely proven to be fair for the user. None of our games have an unfair advantage for "the house" meaning you can win at anything you play!
There is a special promotion right now: Deposit 10DGC and turn it into 100 on either dice or the wheel, and get MATCHED for 100DGC. I actually just did this today and it is not terribly hard to do!
Server is super fast and bets go through at lightning speed! (I am currently placing bets at over 2 per second). There is also no required registration with unique URLs in case you want to jump into play right away.
Note: RPS is still DGC only and in beta.
