Reigning Stanley Cup champions the Chicago Blackhawks got their campaign off to a winning start at the second attempt as they saw off the New York Islanders 3-2 in overtime.
Patrick Kane's powerplay strike less than two minutes into overtime sealed the victory and saw them bounce back from their opening day loss to the NY Rangers.
The game had finished 2-2 after regulation following goals from Artem Anisimov and Kane that were cancelled out by John Tavares and Marek Zidlicky efforts.
The Rangers made it two wins from two after they scored three goals in 77 seconds of the third period to see off the Colorado Blue Jackets 4-2. Brandon Saad's powerplay strike for Blue Jackets looked to have given them the win as they went 2-1 up.
However, a three-goal blast from Oscar Lindberg, Kevin Hayes and Mats Zuccarelloin in just over a minute gave the Rangers an unlikely triumph.
The New Jersey Devils were beaten 3-1 at home to Winnipeg Jets, who made it two wins from two, while the Arizona Coyotes beat Los Angeles 4-1.
Elsewhere, the Detroit Red Wings gave Jeff Blashill a winning start as the Toronto Maple Leafs were swept aside 4-0.
Justin Abdelkader scored a fine hat-trick, with Dylan Larkin also notching, with former Red Wings coach Mike Babcock enduring a nightmare return to his former side.
