For each correct result, 1 point.
For each correct score, a bonus of 3 extra points.
Max points per prediction= 4
To separate out teams with the same points, a version of GD is used.
For each correct score predicted, the total goals in the game are added to your GD.
So, if you got a 2-1 score correct, you would have 3 goals for your GD, but if a 0-0 score was correct, you would, alas, get 0 added to your GD.
During the knockout phase, the prediction is for the score at the end of extra time (NOT including penalties).
So, if a game finished 1-1 at the 90, and 2-1 aet, 2-1 would be the correct score. If a game finished 0-0 at the 90, and 1-1 aet, 1-1 would be the correct score, regardless of the outcome of the penalty shootout.
Games are organised into 3 rounds for the group stage, then the knockout stages.
If you miss some games, you can still post whatever remain, up to kick off.
If I've forgotten something critical, I reserve the right to add (i.e. make up) a rule to cover an unforeseen eventuality.
