Jämtland made a mini jerk in the third period and looked to poke down Norrköping from the league lead.
Halfway into the final period, the home team expanded and led for a while with twelve points.
But the guests came back, and with 17 seconds left of the match, Brandon Tabb put a three-pointer that took the match to extra time.
The team followed suit, and when Carren Wilson Jr put 100-99 to Jämtland in the closing seconds, it looked decided.
But a foul in the last second of extra time changed everything.
Tim Schüberg set both his penalty throws and thus became a great match hero for Norrköping who won by the smallest possible margin, 101-100.
The win was Norrköping's ninth straight in the basketball league.
