Here are the basics to the prediction game (scroll up to get the details to enter, 4 so far): The Group matches (40) are divided into 4 rounds of 8, 11, 9 & 12 games. These follow the order matches will be played. You can post your predictions anytime prior to a game kicking off for it to be included. Once you 'lock' your predictions it will allow you to see others predictions. Once locked you can't change your prediction and if you don't lock it, it will happen automatically when play starts. Points scoring: 1 point for a correct prediction in the Group stages. This increases to 1.5,2 & 3 points thereafter in the Q/F's to the Final. 0.5 points for getting the margin of victory to within 5 points. Must have winning team unless you predicted a margin of 5 points or less. In this case you will still win the bonus even if you predicted the wrong result. 1 Bonus point for being the closest to the winning margin in each match. This in theory could be divided if people are equally close. Grand Slam Point is awarded for getting all the results correct in a given group. This appears to be worth 2 points.
