Reckon it would be a good idea to set up a Tennis Prediction game.. not sure about now because the year is almost over but for next Year.. and give points out for who predicts the Winner of each ATP and WTA events based on the real points system.. so say you predict Nadal to win the Australian Open you get 2000 points.. but if he losses in the final you get 1200, probably work better then the Sweepstake and it's more skill and less luck involved
