Finland had taken the lead twice again.
But Sweden came back after two goals from the giant talent Leo Carlsson.
The 2-2 goal came with less than four minutes left in the game.
But captain Victor Stjernborg was not happy with that.
With Fabian Lysell in the penalty box and with just over a minute left on the match clock, Stjernborg stepped forward and saved Sweden.
The 19-year-old grabbed the puck and scored the match-deciding 3-2 goal.
