The possibility of playing right away without any registration is a very good feature for a newly appeared gambling site. PrimeDice was starting like this, and, as we all know, they have become very successful afterwards. I have a few suggestions on how to improve your site, from my point of view:

1. The faucet with 100 satoshis is a good thing, but it's unclear what is the time interval between claims? It is better to specify that in the pop-up window instead of saying "Slow Down Please", as it is on your site.

2. I don't know about others, but I can't see neither my bets nor my bet history.

3. Although there is a warning when you push the MAX button, a good practice is allowing users to disable the button completely, since if it is there you are tempted to risk all your balance more frequently than if it weren't there(right next to the 2X button).
