Iafallo tied it 1-1 at 7:43, scoring four seconds into a power play. He intercepted a pass behind the net and scored on a wraparound that went between Jones' legs.
The Kings went 1-for-5 on the power play.
The Kraken had a goal waved off for a high stick at 19:53 of the first after Matty Beniers tipped in Justin Schultz's pass from the blue line. The on-ice call was confirmed following a video review.
Kings defenseman Brandt Clarke, the No. 8 pick in the 2021 NHL Draft, made his NHL debut. He had one shot on goal in 15:17 of ice time.
"We dressed six defensemen tonight. I know he wasn't six, pretty sure he wasn't five and I don't believe he was four either. So, that's what I thought of him. I thought he had a real good night," McLellan said.
