Plain-language explanations of the rules and terminology that come up most for families new to the game.
This glossary covers the hockey terms and rules families search for most: what a power play is, how blue lines and zones work, checking vs. cross-checking, how faceoffs work, referee signals and officiating basics, and common shorthand like PIM and "sniper." For equipment sizing, see our equipment guides; for club tiers (AAA/AA/House), see our clubs directory.
A power play happens when the other team has a player in the penalty box, giving your team a numbers advantage on the ice (most commonly five skaters against four). The team with the advantage is "on the power play"; the short-handed team is "on the penalty kill." A penalty typically lasts two minutes for a minor infraction, ending early if the power-play team scores. Coaches usually run a dedicated power-play unit -- a specific group of players who practice this situation together, since it requires different positioning than even-strength play.
A hockey puck is a vulcanized rubber disc, 3 inches in diameter and 1 inch thick, weighing about 6 ounces -- standard across all levels from youth to the NHL. Pucks are frozen before games at higher levels of play so they slide flatter and bounce less on the ice; that's a detail that matters more at the competitive/pro level than for a typical youth practice.
The two blue lines divide the rink into three zones: the defensive zone (in front of your own goal), the neutral zone (the middle third), and the offensive zone (in front of the opponent's goal). The blue lines are what offside calls are based on -- an attacking player generally can't enter the offensive zone ahead of the puck. Not every rink is exactly the same size: NHL rinks are a standard 200 by 85 feet, but international and some other rinks are wider (Olympic-size), and youth/community rinks can vary somewhat, so always check with your specific facility if dimensions matter for what you're doing.
A typical game uses either one or two referees plus two linesmen, depending on the level -- youth games often run with fewer officials than a full four-person crew. Referees signal penalties with specific hand gestures (for example, both fists tapping together for tripping, or a chopping motion to the wrist for slashing) so players, coaches, and fans can identify the call before it's announced. "Misconduct" is a more serious penalty category (typically 10 minutes) for unsportsmanlike conduct, separate from standard minor penalties. Becoming a certified official generally starts through your local USA Hockey affiliate, which runs referee certification clinics for different levels.
Body checking is legal contact used to separate an opponent from the puck, permitted at some age levels and not others -- see our U14 / Bantam guide for when checking is typically introduced. Cross-checking (hitting with the shaft of the stick held in both hands) is illegal at every level. A "donnybrook" is old hockey slang for a fight or brawl -- informal terminology, not an official rules term.
A faceoff restarts play after a stoppage: the referee drops the puck between two opposing players who battle to control it. Winning faceoffs consistently is a real, coachable skill -- it comes down to stick positioning, reading the referee's drop timing, and body positioning to shield the puck once it's won, not just reacting faster than the other player.
The hockey stop (turning the blades sideways to shave off speed) is one of the first advanced skills youth players work on after learning to skate forward and backward -- it takes real practice time and isn't something most beginners pick up in a single session. Crossovers (stepping one skate over the other while turning) build speed around curves, and are foundational for skating agility drills at every level above beginner.
Youth teams typically rotate players through multiple forward and defense positions early on rather than fixing a young player into one position permanently -- specialization tends to happen gradually as players get older and coaches see where a player's skills fit best.
"AAA" and "Tier 1" refer to the same thing -- the highest, tryout-based competitive level in youth club hockey. "Tier 2" generally refers to AA. For the full breakdown of tiers, tryouts, and how to browse real programs by level, see our AAA, AA, and House League directories.
A typical youth hockey season runs roughly September through March, though exact dates vary by association and level. The NHL season is a separate, longer professional calendar -- if you're asking about NHL start dates or the NHL's annual outdoor "Winter Classic" game, that's pro-league scheduling, distinct from youth club seasons, and changes every year, so check NHL.com directly for current dates rather than relying on a static answer here.
Modern ice hockey traces back to informal games played in 19th-century Canada, formalized over subsequent decades into the organized sport played today. We keep this section deliberately brief rather than asserting specific dates or "firsts" we can't verify -- for a properly sourced history, a dedicated hockey history resource is a better reference than a youth-club-focused site like this one.
When the opposing team has a player in the penalty box, giving your team a numbers advantage on the ice (usually 5-on-4). The team with the advantage is on the "power play"; the short-handed team is on the "penalty kill."
One of two lines dividing the rink into three zones (defensive, neutral, offensive). The blue lines are the basis for offside calls -- an attacking player generally can't enter the offensive zone ahead of the puck.
Penalty Minutes -- a player's cumulative time spent in the penalty box over a season.
Faceoff success comes down to stick positioning, reading the referee's drop timing, and body positioning to shield the puck once it's won -- a coachable, practiced skill rather than pure reaction speed.
Body checking is legal contact used to separate an opponent from the puck, permitted at some age levels. Cross-checking -- hitting with the shaft of the stick held in both hands -- is illegal at every level.
AAA (also called Tier 1) is the highest, tryout-based competitive level in youth club hockey, above AA (Tier 2) and House League. See our AAA clubs directory for the full breakdown.
3 inches in diameter, 1 inch thick, about 6 ounces -- standard across youth, college, and NHL play.
Forward (center and left/right wing), defenseman, and goalie. Forwards focus on scoring and forechecking, defensemen on defending the zone and starting breakouts, and goalies use an entirely separate equipment set and skill set from the rest of the team.
