I don't think any sites for dice or any other reliable until your luck is good for you .
Because all this depends upon your luck . If you have a good luck then you can make a better amount of profit but if your luck not more good then you will lost only .
Here I will suggest you to do to take Review first at this forum or at the Google sites  before make gambling , because some sites really are scam and steal your Bitcoin with every bet .
In my opinion if you want to make gambling with dice game then go for the famouse casinos like nitrogensports , directbet , Cloudbet etc .
