Current standings in Group A:

House Martell has pulled ahead significantly and guaranteed their spot in the next round, but the fight for 2nd place is fierce – Tyrell and the White Walkers are separated by only 0.5 points, and there are still 3 games left to be played between them. However, the outcome of the remaining games can also affect the final standings.
