Without sounding like a party pooper I tried something like that a while back, I think MJ did as well.. People did not understand and did not want to play and in the end the regular raffles stood victorious.. Innovation with raffles has always been hard, I know I've tried probably 10-12 different crazy things that IMO are extremely fun but nobody wants to play, as soon as I changed to a regular raffle with the same entry cost the same one fills quickly.. :shrug:
What if it was simple? No picking other than your paid spot or spots 1 through 64 on the bracket?
