All roster announcement dates will be made by the NHL and NHLPA, with each of the participating National Associations selecting its initial six players early in the summer of 2024, prior to selecting its complete rosters later in the year.

All games in the 2025 NHL 4 Nations Face-Off will be played in accordance with NHL rules. Each team will play three tournament games in a traditional “round-robin” format under the following points system: 3 points for a win in regulation time; 2 points for a win in overtime/shootout; 1 point for a loss in overtime/shootout; and 0 points for a loss in regulation time. The two teams with the best tournament record will then advance to a one-game Final.

The overtime format for round-robin games will be three-on-three sudden death for a 10-minute period, followed by a three-round shootout. The overtime format for the one-game Final will be full strength sudden death through successive 20-minute periods until one team scores.
