Kristianstad switched grip on the match already at 4-3 and then just pulled away and in the end it was a question of whether it would be double-digit in the margin of victory but Kungälv could keep the orange-clad, who had the last attack, away.
The Kristianstad players gathered at the center line and celebrated with a ring dance.
46 in the save percentage by Freja Hammer Fagerberg made the goalkeeper selected as Kristianstad's best player in the match.
Mia Lagumdzija, who scored one of six shots, was chosen as Kungälv's best player.
Kristianstad had two six-goal shooters in Siw Aabech and Maja Hansson.
However, Kungälv had the best goal scorer of the match: Maja Fredén scored seven hits and had to pull a too heavy load herself.
Kungälv had started with two victories but now collected the first loss in the early table
