Just don't want this question to get buries so that OP doesn't see it when they do post here:
In a knockout match, which score is the one for the prize:
1) final score including Penalty Kick shootout (can be very high scores, but never a draw)
2) final score at 120mins (could be a draw)
3) final score at 90mins (could be a draw)
Just want to clarify since we're using tournament games and now this question arises.
In any football game if you bet on 'Team A to win 2-1' the score has to be 2-1 in the 90 minutes (plus whatever few minutes injury time there is).
If for example it was 1-1 after normal time & then Team A scores to make it 2-1 after 30 mins extra time then you lose the bet.
So to use DirectBet prediction game as an example you need to predict what you think the score will be in 90 minutes (+ injury time). What happens in extra time or penalties is irrelevent.
If you think it will go to penalties or extra time just predict whatever score the draw is you predict within normal time. I'm pretty sure all of the above is right, that's the way it works in UK bookies.
