I tried out UFC Poker in the hopes of winning some swag. The client is an excercise in frustration. Video ads (with sound) play when you're checking into a tourney, as well as during all breaks. Banner ads are on the side and bottom of every table, and you can't resize the windows or drag them past a certain point. It's like surfing the internet in 1995.
Multi-tabling is sheer chaos. The client will take focus away from a table where it's your turn just to show you that you posted the SB on another table.
Sure, the play is atrocious, but there's no money to be won. I won a seat in the weekly $1,000 game after a single final table finish. 3000 or so players, and here are the payouts:
First place: $750
Second place: $200
Third place: $50
Everyone else goes home with nothing, except for maybe some more points. You'd be far better off playing a freeroll on FT or PS, or a micro buy-in MTT. I know they just started, and might get better, but at the moment, I don't see anything worth recommending to anyone, save perhaps the chance to bust Dana White out of a tournament. Easily the worst poker client I've used to date.
