I registered with the 30 euro bonus and it wouldn't let me play any games. I contacted support and they responded. Unfortunately, according to the terms of this bonus, you cannot play with bonus funds or withdraw them. You need to make a deposit in order to win back winnings from free spins from your real balance. When you fully wager the bonus, the funds will automatically be transferred to your real balance and will be available for withdrawal.
to give you some advice! Is there anything else I can be of assistance to you.

I don't understand what no deposit bonus is that I need to deposit?

Δεν καταλαβαίνω τι μπόνους χωρίς κατάθεση είναι αυτό που πρέπει να καταθέσω;
