With the win, the Golden Knights moved back atop the NHL standings with 84 points – one ahead of Eastern Conference-leading Tampa Bay.
Ryan Carpenter, William Karlsson, Reilly Smith, Luca Sbisa, Erik Haula and Cody Eakin also scored for Vegas, which improved to 23-4-2 at home to set the record for home wins by a team in its inaugural season. It topped the previous mark set by the Gordie Howe-lead 1979-80 Whalers (22-12-6).
Tuch also had an assist and his first fight of the season, giving him the so-called Gordie Howe hat trick.
Marc-Andre Fleury, starting his ninth straight game, made 28 saves for the Golden Knights.
With the score tied 3-3 in the second, David Perron found a streaking Tuch, who beat Rittich from a nice angle and went top shelf to give the Golden Knights the lead for good with 6:02 remaining in the period.
Early in the third, the Flames thought they had tied the game when Sean Monahan smacked the rebound off the end board with a shot Fleury never saw, but a challenge overturned the goal when Calgary was rulled offside.
Vegas then scored three times to seal the win.
Sbisa took Tuch’s pass and launched a one-timer past Rittich to make it 5-3 at 3:17. It was Sbisa’s 100th career point.
Haula got his 23rd of the season when he tipped in Sbisa’s slap shot from the point with 8:45 remaining, and Eakin’s seventh made it 7-3 with 5:42 remaining.
Carpenter gave Vegas a 1-0 lead 2 1/2 minutes in with his sixth goal in nine games, using a tricky behind-the-back, through-the-legs backhand that Rittich didn’t stand a chance against.
Brodie’s fourth goal of the season tied it with 3:15 left in the first as he redirected Travis Hamonic’s slap shot from the point under Fleury’s pads.
On the power play, Karlsson redirected Reilly Smith’s wrist shot with 31 seconds to go in the opening period to give the Golden Knights a 2-1 lead. Vegas has now scored a power-play goal in 13 of its last 15 games. The Flames, meanwhile, came into the game averaging the third-most penalty minutes in the NHL, with 11.0 per game.
Hamilton tied it for Calgary just 20 seconds into the second period, but Smith put Vegas back ahead 3-2 about a minute later with his his 20th.
Tkachuk was credited with his 23rd when Vegas center Cody Eakin lost his stick and attempted to deflect a shot with his skate, but ended up tapping it past Fleury to tie the score with just under nine minutes left in the middle period.
