The 4 Nations Face-Off is here. Four countries are competing against one another in an international hockey tournament for the right to be crowned champions of the world - and the faces of the NHL are all taking part.

For round-robin games, overtime will be held in a 10-minute, three-on-three sudden-death period, followed by a three-round shootout. In the final, full 20-minute, five-on-five periods will be played until a goal is scored.
