Amadio scored on a backhand at the back post off a pass by Brown to put the Kings ahead 3-2 at 12:37 of the third period, but Toews tied it on a wrist shot from the left circle with Crawford off for an extra attacker. Toews ended a run of six straight games without a point.
Chicago rallied to tie the game at 2-2 on Kampf's goal at 17:23 of the first period. Campbell misplayed the puck outside his crease under pressure from Kubalik, giving Kampf a shot into an open net from the slot. Kampf scored for the second time in three games after going the first nine games of the season without a goal.
The Blackhawks cut the margin to 2-1 when Kubalik scored a power-play goal on a wrist shot from the right circle at 8:25. The goal ended an 0-for-21 drought with the man-advantage dating to Oct. 18 against the Columbus Blue Jackets.
Clifford put the Kings up 1-0 at 2:50 on a wrist shot from the left circle. Roy made it 2-0 on a wrist shot from the high slot at 4:29, his first point of the season.
Both goals were the product of an aggressive forecheck, something the Kings had struggled to execute consistently during their losing streak.
"It makes me feel good, but it should make them feel really good," McLellan said. "That's what we want to hang our hat on. I didn't think we played that way for five, six, seven periods, so tonight we were able to sustain it, line one, two, three and four. We just kept handing off good shifts, and momentum was built, and we sustained it."
Crawford came out of the game after allowing Roy's goal. Blackhawks coach Jeremy Colliton said the on-ice officials requested that Crawford be put into the NHL concussion protocol after he took a shot by Kings defenseman Kurtis MacDermid to the mask at 2:41. Crawford went to the dressing room and was replaced by Robin Lehner before returning at 9:47.
Lehner made five saves in relief.
