"How to play" should be added because it is a new game and not all people understand how to play your game. Tried with the free 1000 satoshi bonus and bet all of it in a bet but it says "your bet exceeds 750 satoshi".
No provably fair system? So how do we know that you are not cheating us? Provably fair system is a must if you want to gain players. Otherwise, no one would be interested to play no matter how unique your game is.
