I have a small issue with their T&C - not because of their rules, but the way it's worded and positioned on their site:
The problem lies in the fact that in point #1 they simply say that the restricted games won't count towards meeting your WR. If a player didn't read any further and took that for face value, they would forfeit any winnings, as it's stated in point #3.
Why would they have their T&C page setup like that in the first place? Why not just simply say in 1 paragraph that any bets placed on restricted games would void any winnings? Why say one thing in one paragraph and have totally different information in another paragraph further down the page?
edit: After another reading of point #3, I see that their statement is pretty ambiguous. Are they going to void ALL of a player's winnings, or just winnings generated from a restricted game? And on the flip-side, are they going to refund a player's losses if they play a restricted game and lose?
If they're only going to void winnings made from a restricted game, they're just setting themselves up for bonus abuse. A player could simply go in, double or triple their BR on a restricted game then grind away the WR on allowed games and still cash out ahead even with the extra $ being taken away from their winnings on a restricted game.
