Mens 2023 playing system is below.
For the Men’s Division, the NAI has adopted the widely-praised tournament format of the Aleš Hřebeský Memorial, with teams competing in Gold and Silver pools/brackets. The winners of the Gold pools advance directly to the quarterfinals. The second/third place teams from the Gold pools and the winner of the Silver groups will advance to play-in games (winners to quarterfinals, losers to 9-16 bracket).
All 34 men’s teams will be guaranteed 5-6 games and will compete to a final ranking. The third place teams from the Gold pools will advance to the 9-16 bracket.
The second place teams from the silver pools (and third place teams from the four-team silver brackets) will advance to the “Y Pool” featuring teams competing for final placements 17-26. Y Pool teams will play two randomly-selected games against each other. Following the two games, the top-four teams in the Y Pool standings will advance to the 17-20 bracket. Remaining teams will advance directly to final placement games based on the standings.
The last place teams from the silver pools will advance to the 27-34 bracket.
U-18 Division, 2023 format follows: teams are divided into three pools of three teams each. Pool winners plus the top second place team (goals against is the primary tiebreaker) will advance to the Championship Semifinals. The two remaining second place teams will join the championship semifinal losers in the 3rd Place Semifinals. The three third place teams will compete in a round-robin for 7th place. All teams compete to a final ranking and will play four or five total games.
Womens Division, 2023 format follows: Each team will play two preliminary games. Following the preliminary games, the top four teams will advance to the championship semifinals while the bottom four will compete in the consolation (5th place semifinal) bracket. Goals against is the primary tiebreaker. All teams compete to a final ranking and will play four total games.
U-18 Division TBD, 2022 format follows: teams are divided into two pools of three teams each. Pool winners get a bye to the semifinals. 2nd/3rd place teams compete in play-in games. All teams compete to a final ranking and will play four or five total games.
In all games across all tournaments/divisions requiring standings, the winning team gets three points. If the score is tied after regulation, each team gets one point, and the team winning the overtime receives the additional point. If necessary, the following tiebreakers are used in order of priority:
1. number of points;
2. head-to-head record between all tied teams;
3. fewest goals allowed;
4. fewest penalty minutes;
5. coin toss.
Note: In the event of more than two tied teams, only one team earns a playoff seed in any tie-breaking step. Remaining tied teams revert to the first step of the tie-breakers.
To be clear, there is never a benefit to “running up the score” on an opponent.
