I have another suggestion for you: After registering my account, I get 0.00003000 BTC in my account balance while the min bet in dice is 0.0001 btc, and so I am unable to make a test bet without depositing my bitcoin. IMHO, it is better to to have a lower min bet (something like 0.00001 btc for example) so that new visitors can make a few test bets to see if/how the site works.
BTW, good luck with your new dice game!
