Tried the demo, interface is very simple. It is my first time seing a game like this so we just need to guess from number 1 to 5? What about the minimum bet? Is it 1Bitcoin or it is just for demo?
In demo the minimum bet is 1 Bitcoin but for sure this cannot be the case in real gamble. If they demand minimum 1 Bitcoin for a real game, then I am sure no one will play there.

Hahaha yeah this is unrealistic if in real games you will bet a 1 Bitcoin this is a huge amount of money and no one can risk 1bitcoin.
By the way the site still simple no improvement but this is early to said that there will be more times to happen just wait for more update but over all its mobile friendly in my smartphone so this is a good advantages to take step up.
