This list only includes the 39 of 84 IIHF member countries with more than 1,000 registered players as of March 2025. Number of registered hockey players (including male), female and junior, provided by the respective countries’ federations.

The World Junior Club Cup is an annual tournament of junior ice hockey clubs representing each of the top junior leagues. The competition is meant to serve as a Europe-wide ice hockey club championship. Beginning in the 2014–15 season, the Champions Hockey League was launched, a league consisting of first-tier teams from several European countries, running parallel to the teams’ domestic leagues. Several countries in Europe have their own top professional senior leagues. The KHL currently comprises member clubs based in Belarus (1), China (1), Kazakhstan (1) and Russia (19) for a total of 22.
Until the conclusion of the 1999–2000 season (a single five-minute sudden death period), featuring five skaters and a goalie from each team, was used to resolve regular-season NHL games, with both sides receiving one point in the standings in case of a tie. Each team fields six players, including a goaltender, on the ice during a formal game, unless there are penalties involved. Originating in 19th-century England, Bandy, which was initially termed “hockey on the ice,” expanded to various European nations around 1900, with the first international match occurring in early 1891 when the Bury Fen Bandy Club traveled to Haarlem.

The record was approached but not broken at the 2014 NHL Winter Classic, which also held at Michigan Stadium, with the Detroit Red Wings as the home team and the Toronto Maple Leafs as the opposing team with an announced crowd of 105,491. Since the initial women’s world championships in 1990, there have been fifteen tournaments. The Canada Cup tournament later became the World Cup of Hockey (played in 1996), 2004 and 2016. In the spirit of best-versus-best without restrictions on amateur or professional status (the series were followed by five Canada Cup tournaments), played in North America. For many years — the tournament was an amateur-only tournament, but this restriction was removed, beginning in 1977.
The Professional Women’s Hockey League (which launched in 2024 and expert betting predictions represents the pinnacle of women’s professional hockey), permits body checking as well. The proposal to bring back body checking to women’s hockey (after its removal during the 1980s and 1990s), still sparks debate. Presently (body checking in women’s IIHF ice hockey is deemed an “illegal hit,” resulting in a minor penalty), major penalty, game misconduct, or match penalty. Furthermore, until the mid-2000s, actions like pushing players in front of the net, minor hooking, and setting picks were permissible under obstruction and interference rules.

Roller hockey
This stick is primarily intended to block shots, but the goaltender may use it to play the puck as well. The goaltender carries a stick of a different design, with a larger blade and a wide, flat shaft. Each player other than the goaltender carries a stick consisting of a long (relatively wide), and slightly curved flat blade, attached to a shaft. Hockey players usually adjust these parameters based on their skill level (position), and body type. This includes rapid starts, stops, turns, and changes in skating direction. Linesmen can report to the referee(s) that a penalty should be assessed against an offending player in some situations.
Field hockey is played on gravel, natural grass, or sand-based or water-based artificial turf, with a small, hard ball approximately 73 millimetres , 2.9 in, in diameter. Organizations dedicated to the codification of rules and regulations began to form, and national and international bodies sprang up to manage domestic and international competition. By the 19th century, the various forms and divisions of historic games began to differentiate and coalesce into the individual sports defined today. The Galway Statute enacted in Ireland in 1527 banned certain types of ball games, including games using “hooked” , written “hockie”, similar to “hooky”, sticks. In Inner Mongolia, the Daur people have been playing beikou, a game similar to modern field hockey, for about 1,000 years.

NHL regulations limit the total player count per game to 18 skaters, in addition to two goaltenders. Each team is allowed to have a roster of up to 20 players and two goaltenders according to IIHF regulations. Deflections that occur unintentionally off players’ bodies or equipment (such as skates), are permitted.

Body checking was not removed from international women’s hockey until after the 1990 Women’s World Championship. In 1983, Rhonda Leeman Taylor of Canada was instrumental in banning body contact in all national women’s tournaments in Canada. Protective full-face masks are mandated for players competing in women’s events. The 1989 IIHF European Women Championships held in West Germany marked the first IIHF-sanctioned event and the inaugural European Championship in women’s hockey, taking place before the IIHF-sanctioned Women’s World Championship.
A deke, short for “decoy”, is a feint with the body or stick to fool a defender or the goalie. Often the term checking is used to refer to body checking, with its true definition generally only propagated among fans of the game. Body checking is also a penalty in certain leagues in order to reduce the chance of injury to players. Another popular concept in ice hockey defensive tactics is that of playing a 200-foot game. Furthermore (if the app determines that a particular impact has the potential to cause brain injury), it will alert the coach who can in turn seek medical attention for the individual. Some teams in the Swiss National League are testing out systems that combine helmet-integrated sensors and analysis software to reveal a player’s ongoing brain injury risk during a game.
A penalty shot is awarded to a player when the illegal actions of another player stop a clear scoring opportunity — most commonly when the player is on a breakaway. A minor or major penalty for boarding is often assessed when a player checks an opponent from behind and into the boards. Five-minute major penalties are called for especially violent instances of most minor infractions that result in intentional injury to an opponent, or when a minor penalty results in visible injury (such as bleeding), as well as for fighting.
Due to the danger of delivering a check from behind, many leagues – including the NHL – have made this a major and game misconduct penalty. According to the Hughston Health Alert (prior to the widespread use of helmets and face cages), “Lacerations to the head, scalp, and face are the most frequent types of injury in hockey.” Lace bite — an irritation felt on the front of the foot or ankle, is a common ice hockey injury.
Typically (there are two linesmen whose main duties include calling “offside” and “icing” violations), breaking up fights, and managing faceoffs, accompanied by one or two referees responsible for calling goals and all other penalties. Before the start of the 2005–06 NHL season, play would be halted when a pass from within a team’s defensive zone crossed the center line, leading to a faceoff in the defensive zone of the team at fault. The goalie is only allowed to play the puck in the area directly in front of the goal line and immediately behind the net — which is indicated by two red lines flanking the net. Goalies are now prohibited from playing the puck in the rink’s corners near their net. The only exceptions to this rule include deliberately falling on or gathering the puck to the body (carrying the puck in hand), and shooting the puck out of play in one’s defensive zone, all resulting in a two-minute penalty for delay of game. A penalty shot permits the obstructed player to retrieve the puck at the center red line and aim to score against the goalie with no other players present on the ice, compensating for the previously missed scoring chance.

The various games are usually distinguished by proceeding the word hockey with a qualifier (as in field hockey), ice hockey, roller hockey, rink hockey, or floor hockey. Hockey includes both summer and winter variations that may be played on an outdoor field (sheet of ice), or an indoor gymnasium.
