Champions Hockey League

The Champions Hockey League is a European first-level ice hockey tournament. Launched in the 2014–15 season by 26 clubs, 6 leagues and the International Ice Hockey Federation (IIHF), the tournament features top teams across Europe.

Background
The IIHF launched a tournament with the same name in 2008 to coincide with the IIHF's 100th anniversary. The tournament's only season was played between 8 October 2008 and 28 January 2009, and was won by the ZSC Lions who got to play in the 2009 Victoria Cup game as a result. The IIHF planned to launch another season but was ultimately forced to cancel the tournament due to problems finding sponsors during the concurrent global economic crisis and failure to agree on a tournament format. On 9 December 2013, a new tournament with the same name was launched by the IIHF and a group of 26 clubs from six countries, born out of the European Trophy, starting in the 2014–15 season.

Each team played a double round-robin in their group, for a total of 6 games per team. The 11 group winners as well as the top five group runners-up qualified for the playoffs. The playoffs were as a single-elimination tournament, with all rounds leading to the final played in two-game, home-and-away, total-goal series. The final was a single game. In total, 161 games were played, including the group and playoff stages. The season was won by Luleå HF which defeated Frölunda HC in the final.

Teams
Starting in the 2017–18 season, 32 teams again participated in the group stage, with 24 of the entries coming from the six founding leagues (Swedish Hockey League, Finnish Liiga, Swiss National League A, Czech Extraliga, German DEL and Austrian/international EBEL) and all berths being earned through on-ice achievement: the "founding clubs" were no longer guaranteed a place in the competition. A maximum of five teams from each country were permitted, with the entries allotted to each country according to a coefficient system (best two leagues got five berths, next two got four, last two got three). The remaining eight places were given to the champions of the Norwegian, Slovak, French, Belarusian, Danish, British and Polish leagues, as well as the champion of the Continental Cup. The teams were then drawn into eight groups of four, with the top two teams in each group advancing to the knockout stage, which was contested as two-legged ties until a one-match final.

In the first three years of the competition, the 26 founding teams had guaranteed spots in the group stage ("A license"). Additional teams from the founding league, that qualified based on sporting merits ("B license") and the champions from other European leagues ("C license") completed the field.

A new competition format was introduced for the 2023–24 season. 24 competing teams are allocated as follows:
 * The previous CHL season's champions
 * 3 teams representing the Swedish Hockey League
 * 3 teams representing the Finnish Liiga
 * 3 teams representing the Swiss National League
 * 3 teams representing the Czech Extraliga
 * 3 teams representing the Deutsche Eishockey Liga
 * 3 teams representing the Austrian ICE Hockey League
 * 5 wild card teams from various European leagues (maximum of 1 wild card per league)

Note: It was decided that the 2021–22 season would not be accounted for.

League ranking points calculation
Each match is counted for league ranking points. Points collected by all teams from a specific league are summed up and then divided by number of teams from that league. The final result represents the league's coefficient for that year. Coefficients are then sorted from highest to lowest: the best league gets 100 points with each following getting five points less than previous one (95, 90, 85...).

Points are awarded as follows:
 * win in regulation time – 3 points (group stage, playoffs)
 * win in overtime – 2 points (group stage only; no overtime in playoffs)
 * tie in regulation time – 1 point (playoffs only)
 * loss in overtime – 1 point (group stage only)
 * loss in regulation time – 0 points (group stage, playoffs)

Additionally, each team is awarded 1 point for reaching each of next rounds.

The last four seasons are taken into account for berth allocation for the 2018–19 season. League points are made of 25% of points won in first season, 50% of points won in second season, 75% of points won in third season and 100% of points won in last, fourth season.

For the 2018–19 season, each of the four previous seasons was taken into account and starting with 2019–20 season each will be based on points from last five seasons.

Prize money
In the 2014–15 season, 40 teams competed for a grand total of 1.5 million euros.
