What you guys should do is create a thread under the Bitcointalk forum under "Gambling" and post this dice game there.
I am sure there are many old bitcoin adopters who claimed the Byteball distributions last year and would like to have some fun with their coins. Might bring out the awareness for Byteball. The gambling section is a pretty big part of Bitcointalk.
I think your ideas is very good, which might bring Byteball to more crypto enthusiasts.
More attention on this coin, high capital to come later.
So far, Byteball team have made nice initiatives to develop the project well and very far away from its beginning years ago.
