Goals, Assists, Game Structure, Overtime & Shootout — A Complete Beginner's Guide
Last updated: March 1, 2026
In ice hockey, teams score by shooting the puck into the opponent's net. Each goal is worth 1 point. A regulation game consists of 3 periods of 20 minutes each, with the clock counting down from 20:00 to 0:00. If the score is tied after regulation, the game goes to overtime (5 minutes of sudden death in most formats) and, if still tied, a shootout. Players also earn individual assists (up to 2 per goal) for passing the puck to the goal scorer.
The fundamental unit of scoring in ice hockey is the goal. A goal is scored when the puck completely crosses the goal line between the posts and under the crossbar. Every goal counts as 1 point for the scoring team — there are no 2-point or 3-point goals in hockey.
Up to two assists can be awarded on each goal:
If a player scores without any teammates touching the puck beforehand (e.g., stealing the puck and scoring solo), the goal is recorded as unassisted.
In hockey statistics, a player's points are calculated as goals + assists. A player who scores 1 goal and has 2 assists in a game has 3 points. The points leader in a league or tournament is typically the player with the most combined goals and assists.
This system means that playmakers who set up goals are valued alongside pure goal scorers. Many of the greatest hockey players in history — Wayne Gretzky, Jaromir Jagr, Mario Lemieux — accumulated more assists than goals over their careers.
Goals are categorized by the situation in which they are scored:
A standard ice hockey game is divided into 3 periods, each lasting 20 minutes of playing time. The clock counts down from 20:00 to 0:00 in each period.
| Period | Clock | Description |
|---|---|---|
| 1st Period | 20:00 → 0:00 | Opening period |
| 1st Intermission | ~15-18 min | Ice resurfacing, teams rest |
| 2nd Period | 20:00 → 0:00 | Middle period |
| 2nd Intermission | ~15-18 min | Ice resurfacing, teams rest |
| 3rd Period | 20:00 → 0:00 | Final regulation period |
Unlike football (soccer), the hockey clock stops whenever play is whistled dead — for penalties, icing, offside, goals, or any other stoppage. This means a 20-minute period can take 35-45 minutes of real time. The clock only runs when the puck is in active play.
Between periods, teams leave the ice for intermissions lasting approximately 15-18 minutes at the professional level. During this time, the ice is resurfaced by a Zamboni machine, teams adjust their strategy, and players rest. At the NHL level, intermissions include television timeouts and analysis segments.
Teams switch ends after each period. This ensures fairness, as one end of the rink may have subtle advantages (proximity to the team's bench, lighting, or ice conditions).
Regulation playing time is exactly 60 minutes (3 × 20). If the game is tied after 60 minutes, it proceeds to overtime.
Hockey's penalty system directly affects scoring by creating power play situations — when one team has more skaters on the ice than the other.
| Penalty | Duration | Short-Handed? | Ends Early on Goal? |
|---|---|---|---|
| Minor | 2 minutes | Yes (5v4) | Yes — penalized player returns |
| Double Minor | 4 minutes (2+2) | Yes (5v4) | First segment only — second begins immediately |
| Major | 5 minutes | Yes (5v4) | No — served in full regardless of goals |
| Misconduct | 10 minutes | No — substitute plays | N/A (team at full strength) |
| Game Misconduct | Ejection | No — substitute plays | N/A (unless combined with minor/major) |
| Match Penalty | Ejection + review | Yes (substitute serves 5 min) | No — full 5 minutes |
A power play is the most common route to scoring outside of even-strength play. When a player commits a penalty, they sit in the penalty box and their team plays with one fewer skater — typically 5-on-4. The team with the extra player has a significant advantage: at the elite level, power play conversion rates of 20-25% are considered strong.
If a second opponent is penalized before the first penalty expires, the power play becomes 5-on-3 — an extremely dangerous situation for the short-handed team.
The most important rule about penalties and scoring: if the team on the power play scores during a minor penalty (2 minutes), the penalized player immediately returns to the ice and the teams go back to even strength. This does not apply to major penalties — those are served in full regardless of how many goals are scored.
A player's or team's accumulated penalty minutes are tracked as a statistic called PIM (Penalty Minutes or Penalties in Minutes). High PIM typically indicates an aggressive or undisciplined style of play.
If the score is tied at the end of 3 regulation periods, the game enters overtime. Overtime rules vary significantly depending on the league and competition format.
The 3-on-3 format was introduced in 2015 to create more open ice and increase the likelihood of a goal before the shootout. It produces exciting end-to-end action.
Playoff overtime games are among the most dramatic moments in hockey. Some games have required 4, 5, or even 6 overtime periods to resolve — over 100 minutes of additional playing time.
The critical strategic distinction: in regular season games (NHL or IIHF group stage), teams know a shootout is coming if they survive overtime without conceding. In playoff or elimination games, teams must play until someone scores — there is no shootout safety net.
A shootout is used to decide games that remain tied after overtime in regular-season or group-stage play. It is essentially a penalty shot competition.
In most leagues, shootout goals and saves are tracked separately from regular game statistics. A shootout-decided game is officially recorded as a one-goal victory (e.g., 3-2) — the winning shootout goal is credited to the player who scored it, but individual shootout attempts beyond the decider are not counted as regular goals or saves.
Several game situations create unique scoring dynamics that every hockey fan should understand.
When a referee raises their arm to signal a penalty against Team A but has not yet blown the whistle (because Team B still has the puck), Team B is on a delayed penalty. During this time:
A team may choose to pull their goaltender — replacing the goalie with an extra skater — to create a 6-on-5 advantage. This typically happens:
The risk is enormous: the opposing team can shoot the puck into the unguarded net from anywhere on the ice. An empty-net goal is one of the easiest goals to score but only becomes available when the trailing team makes this calculated gamble.
Each team is allowed a maximum of 6 players on the ice at any time (typically 5 skaters + 1 goaltender). If a team has too many players on the ice during active play, they receive a 2-minute minor penalty. Line changes in hockey happen during play ("on the fly"), which occasionally leads to brief overlap — the rule allows a small buffer zone near the bench, but if an extra player is actively involved in play, the penalty is called.
If an attacking player makes contact with the goaltender in the crease (the blue-painted area in front of the net) that prevents the goaltender from making a save, the goal may be disallowed for goaltender interference. This is one of the most debated calls in hockey, as the line between incidental and deliberate contact is often subjective.
No. Every goal in hockey is worth exactly 1 point. There is no concept of a more valuable goal based on distance, difficulty, or game situation. The only way to score is to put the puck in the net, and every goal counts equally.
In most hockey at the professional and international level, the clock counts down from 20:00 to 0:00 each period. This is the opposite of football (soccer), where the clock counts up. Some recreational and youth leagues may use count-up clocks, but the standard in NHL, IIHF, and Olympic hockey is countdown.
Only in regular-season or group-stage games. In the NHL playoffs, there is no shootout — overtime periods continue until someone scores, no matter how long it takes. In the Olympic gold medal game, the same applies: unlimited sudden-death overtime with no shootout.
Not necessarily. A misconduct penalty (10 minutes) removes a player from the game for 10 minutes, but a substitute takes their place — the team plays at full strength. Only minor, double minor, major, and match penalties create a power play situation.
No. Only teammates of the goal scorer can earn assists. A maximum of 2 assists (primary and secondary) can be awarded per goal, and they always go to players on the same team as the scorer.
If a goal is scored at the exact buzzer, video review determines whether the puck crossed the line before time expired. Additionally, if a penalty is committed before time expires, the power play carries over even if the clock hits 0:00 — the period is extended until the face-off and subsequent play are complete. And in overtime sudden death, the game ends only when a goal is scored, regardless of the clock.
