welcome to the forum, i didn't find any faucet button on your site but i just got 20 credits from my new account and tried the game buy tickets there, good luck
I just checked the credits value from the deposit button for 500 credits equivalent to 0.00029477 BTC whether it's a fixed price or will change at any time
just a little suggestion to add other crypto will be more interesting there
Click on your balance and a drop down menu showing Transactions, Deposits, Withdrawals and Faucet option will appear.
Wondering the same about what monetary unit used on the site is. Considering only deposit/withdrawal option is Bitcoin , at least at the moment, why don't display players balance in bitcoin directly ? Maybe using bits like some popular gambling sites do?
