paradise gift tree

anyone know if u can play in this tourney if your not 21+. Since u get to pick a number from a package and they give u a random prize. Could be wsop prize, wpt prize, 25,000, a masters 2000 dollar buyin . if i pick a number and it ends up beign a wsop prize what will happen? This is very confusing since u might pick a number that ends up beign a wsop prize package since it is not transferable.
