I wasn't able. I'm guessing because of my low post count. Support cease to reply once you ask (in detail) about the 25x deposit+bonus.  They also stated it's 1-2% on casino games after their t&c say 5% on their site.  Either way, the site itself is manipulating people and you'd want a mathematician with ya while you're trying to understand the bloody thing.

I asked about withdrawing my original deposit to get the hell out of there and the guy tells me, "oh your actual deposit money is used up first, ahead of bonus, so you need to bet 25x your deposit + bonus"

So then I go and bet almost 10,000EUR throughout the day and email again to be told only 1-2% of my bets are gone towards it. So that amounts to 200EUR.

Work it out, it's absolute bobbery once you go through all the terms and conditions. Wanks!
