A Pawn can only reach the North Pole from the direction that is marked with a boot on the North Pole Disc.
A Pawn can move on the squares around the North Pole normally, but cannot diagonally step over the North Pole Disc to the opposite side.
From the surrounding four squares it is still one more step to the North Pole.
The final step can be made with any card with a boot symbol on it, be it diagonal or straight.
As soon as a Pawn steps on to the North Pole, place it on the Scoreboard.
