Sean Monahan and Matthew Tkachuk scored in their shootout attempts, while neither of the Florida Panthers skaters could convert as the host Calgary Flames won a wild and crazy 6-5 shootout clash on Thursday.

Calgary goalie David Rittich struggled through overtime with only 18 saves, but denied both Jonathan Huberdeau and Aleksander Barkov in the showdown to close out a game in which multiple leads were lost by both teams.

Calgary Austin Czarnik's lucky power-play goal that opened the scoring at 8:17 of the first period -- his shot was going wide but banked off the skate of Florida's Aaron Ekblad -- was the first clue it would be wild affair. But Huberdeau tied it at 4:28 of the second period when he stole the puck in the neutral zone and buried a shot from the wing on the ensuing rush.

The clubs traded goals again in the second period. Tkachuk put the Flames ahead a second time just before the 12-minute mark when he rifled a shot from the wing, but Florida's Mackenzie Weegar evened the count at 15:15 by wiring a wrist shot from the high slot.

Tkachuk's second goal of the game -- a redirect of Michael Frolik's pass during a two-on-one rush -- 32 seconds into the third period put the Flames ahead a third time. Mark Giordano made it a 4-2 game at 5:16 with another goal off the rush, giving the hosts belief they were en route to victory.

However, the Panthers not only tied it up but took a temporary lead. First, Josh Brown wired a point shot at the 6:20 mark, then Evgenii Dadonov converted during a two-on-one rush with Huberdeau a couple of minutes later and Mark Pysyk's first goal of the season with 5:01 left in regulation gave the Panthers a 5-4 lead.

But Sam Bennett pounced on a loose puck and chipped it home with 2:43 left to force extra time.

Goalie Sergei Bobrovsky made 19 saves, and Barkov collected four assists for Florida, which is on a 3-0-4 run.
