Also I don't know if this was intentional or not but when you tap "PLAY!" you see the 3 dice rotating and it takes like 5 seconds to get the bet to actually process. Its fine at first but after a few hundreds of bets people won't like the delay, maybe make the delay 1 second instead to prevent any bots.
The delay is the effect of the animation, so probably adding an option to disable the animation will be better so players can choose whether to see the animation or not when playing. Just like in other sites that has an animation on their game but they have an option to disable the animation so players are getting instant bet.
I've tried it out on mobile and was pretty easy to navigate. However it took me a while to find the faucet first, maybe make a direct link somewhere to the faucet. Basically for anyone that can't find it on mobile, just tap on your balance and click the 3rd button from the left, basically the hand holding the BTC.
I have to agree with this one, faucet is like located in a hidden place so move it to (maybe) the next to balance without clicking the account tab is better.
