Have you read the rules of the Contest at least once? I guess, not.
The winner of the contest is only one person who predicts the most. And he gets the whole prize. The main task is to predict the correct score. If more than one person predicts the final score, the winner will be the one who guesses not only the correct score but also any goalscorer in the match. You predicted the score, as 11 other participants but you didn't guess the goal scorer right.
