It seems there are no any free rolls now.
When tried,it says 'you dont have enough balance'
If it says 'you dont have enough balance' that mean you dont have enough balance
You have to look on the left side - there look for "freeroll" This games are for free.. When you win something and your balance will be high enough to pay entry then you can participate in "payroll" games
Edit: Of course if you want play in "payroll" now - you can, but you have to deposit some btc..
