I only win tickets for the omaha freeroll and unlike the holdem, the omaha tournament only happen one time per day and the time is awful for me. I wish I could play the 12 days because it's a great tournament, but I could only play 6-7 days so far.
Yes I play them when I can, I won a few cash dollars and then I played cash games and managed to triple the money. Very nice promotion. You just need some luck in the freeroll.
