For example, if you predict a 1-1 draw between Liverpool and Madrid, you'll score 3 points if the final result happens to be 1-1 (between Madrid and 'Pool). If they draw 0-0, you'll get 1 point for predicting the right outcome, even if not the right score.
Similarly, if you predict 2-0 win for Arsenal against Dortmund, you'll get 3 points if the result is indeed 2-0 win for Arsenal. If Arsenal win 2-1, you'll get 1 point for predicting the right winner.
If you don't get the winning team right, or predict a draw when the result is actually a win for either side, you'll get 0 points. Say, you predicted a 2-2 draw between Barca and Real. If it's actually a win for either, you don't get any points. I hope this is clear now.
