NHL overtime rules
The NHL has gone through a number of changes to its overtime format.
Before the 2015-16 season, the league adopted the 3-on-3 OT. The AHL and ECHL had used this format before the NHL decided to implement it in place of 4-on-4.

History of NHL overtime rules
The NHL utilized a 5-on-5, 20-minute overtime period in 1921 before slimming it down to 10 minutes in 1927. At the time, the league still used the sudden-death format.
In 1928, the league changed to non-sudden death, meaning the period would run for the entire 10 minutes, no matter if a goal was scored. If the game remained tied at the end of OT, it was declared a draw.
In 1942, due to wartime restrictions with train schedules, overtime was eliminated from regular-season play. Any game tied after regulation would end in a tie, however, in the playoffs, the league continued to have 20-minute sudden-death OT periods.
The NHL reimplemented the OT period, in the regular season over 40 years later, this time with a five-minute, sudden-death period. The league continued with the 5-on-5 format until 1999, when it changed to 4-on-4 play for the regular season.
It was also the same season that teams got a point if they lost in OT and two points for winning. If no team scored in OT, both teams earned a point.
The shootout was put in place in 2005 after the NHL lockout. If no team scored in the overtime frame, then a shootout would decide the winner. This eliminated ties completely in the game of hockey.
Finally, the current 3-on-3 format was adopted in 2015, and there have been no plans on going away from it.
