Ice hockey is a fast-paced team sport played on an ice rink between two teams of six players each, including a goaltender. The objective is to score goals by shooting a puck into the opponent’s net using a curved stick. Ice hockey is particularly popular in North America and Northern and Eastern Europe.
The sport is governed internationally by the International Ice Hockey Federation (IIHF).
History
Ice hockey developed in Canada in the late 19th century, influenced by earlier stick-and-ball games. The first organized indoor game was played in Montreal in 1875.
Professional leagues began forming in the early 20th century. The National Hockey League (NHL) was established in 1917 and has since become the premier professional league in the world.
Ice hockey has been part of the Winter Olympic Games since 1920 (men) and 1998 (women as a full medal event).
Rules and Gameplay
A standard ice hockey game consists of three 20-minute periods with intermissions between each period.
Basic Structure
- Six players per team on the ice (one goaltender, five skaters)
- Unlimited substitutions during play (line changes)
- Offside and icing rules regulate puck movement
- Physical contact (body checking) is permitted within the rules
Scoring
- A goal counts as one point
- If tied at the end of regulation, overtime is played
- In some competitions, a shootout determines the winner if overtime ends tied
Penalties
Infractions result in penalties that require the offending player to serve time in the penalty box, typically two, five, or ten minutes. During minor penalties, the penalized team plays shorthanded.
