The Boston Bruins have become the winningest team in NHL history, while a New York Islanders defeat boosted the Florida Panthers' and Pittsburgh Penguins' hopes of securing a playoff spot.
The race for the remaining second Wild Card in the Western Conference is down to two teams after the Calgary Flames were knocked out of contention, and the Winnipeg Jets are expected to make it over Nashville Predators after a big win against San Jose Sharks.
Three divisional titles are yet to be decided, making the final week of the NHL season a fascinating one to see who matches up with who when the Playoffs start.
The Boston Bruins have surpassed the 2018/19 Tampa Bay Lightning and the 1995/96 Detroit Red Wings' record of most wins in an NHL regular season, beating the Philadelphia Flyers 5-3 to record their 63rd victory (63-12-5).
Forward David Pastrnak became the second player to reach 60 goals this season, with Connor McDavid of the Edmonton Oilers at 64.
Each team has two games remaining and Pastrnak is +1600 to overtake McDavid to win the Rocket Richard Trophy as the league's top goal-scorer.
The Bruins are +300 to go on to become Stanley Cup Champions for the first time since 2011, a feat which neither the Lightning nor Red Wings managed after their historic seasons.
The Panthers lead the Islanders by one point and the Penguins, who have one game in hand, by two points for the first Wild Card from the Eastern Conference.
The Panthers will end their season at home against the Carolina Hurricanes on Thursday where they are a strong 23-12-5 and they are -300 to secure a post-season place.
The Islanders’ defeat to the Capitals was a costly one, as they have just one game remaining at home against the Montreal Canadiens and now must rely on the NHL’s bottom two teams taking points from the Penguins.
New York are one point ahead of Pittsburgh in the second Wild Card position while the Penguins are -225 to take enough points on the road from Chicago Blackhawks and Columbus Blue Jackets to secure a 17th consecutive playoff berth.
The Winnipeg Jets closed in on a Stanley Cup Playoff position with a 6-2 win against San Jose.
The Jets are three points ahead of the Predators for the second Wild Card from the Western Conference with two games remaining. Both games are on the road for Winnipeg against Minnesota Wild and Colorado Avalanche.
Nashville eliminated the Calgary Flames from contention with a 3-2 shootout win on Monday. The Predators also play the Wild and Avalanche to end their season but do so at home.
Carolina are one point ahead of New Jersey Devils and two above New York Rangers, who gained a point in a shoot-out loss to the Buffalo Sabres. Carolina and New Jersey each have two games remaining and New York have one.
The Oilers have won seven in a row and the five as each team aims to move up in the Pacific Division in the final week of the season.
Edmonton are two points behind the Vegas Golden Knights for first place in the division and each have two games remaining.
Seattle have already secured a playoff spot at least via the first Wild Card from the Western Conference but are just two points behind Los Angeles King for third place in the division which brings with it a higher seeding.
The Dallas Stars moved back into a tie for first place in the Central Division with a 6-1 win over in a game which saw Joe Pavelski register his 1,000th NHL point.
Reigning Stanley Cup Champions Colorado Avalanche currently hold top spot based on having more regulation wins and they also have a game in hand.
Dallas finish the season with two a double header at home against St. Louis Blues.
The Avalanche have two home games against the Oilers and Jets and a road trip to Nashville to end their regular season campaign.
