I agree with the previous posters who have stated Gameduell will not pay out. I have made around 6 withdrawal requests in the last year, not for any large amounts as I simply don't play that well. 2 of these requests were paid - for around £30 GBP total, the other 4 are not being paid. First they asked for ID which I provided, they are now asking for me to video myself playing and send it into them so they can see how I am doing so well.
Firstly I am not doing very well and am around average statistics wise, secondly they have refused to pay out unless I send this video and it cannot be wobbly, and must fulfill all sorts of other criteria. Clearly they simply don't want to pay.
