I've been playing all football season, only lost twice. Typically I just do 1 per week (only $5), unless a friend challenges me, which I'm 12-0 all time vs friends so they stoped challengeing me. I don't go for the crazy, unrealistic contests. I do the 50/50's. All you have to do is beat half of the players in that contest, which is honestly really easy, as long as you know a decent ammount about that sport. I've had a lot of success on football, and did fairly well in baseball. Hockey, at least for me, is just impossible, the few times I tried I came in dead last.
