How long are penalties in adult games, and does my team play short after a major?

Penalty lengths in Adult classifications (actual playing time, not scaled to period length):

The option to shorten majors, misconducts and match penalties doesn't apply to adults.

Major plus game misconduct, or a match penalty (adult rule):

• Your team doesn't have to put a substitute in the penalty box.
• The team plays short-handed for the penalty time. When it expires, the team can add a player from the bench to return to full strength.

Other penalty basics:

• A power-play goal ends the first non-coincidental minor being served.
• Equal penalties to both teams (coincidental) are replaced immediately on the ice, and those players come out at the first stoppage after their time is up.
• A player who's both penalized and injured may go straight to the dressing room, with a substitute serving the time.
