In WLAF/NFL Europe, however, the overtime period lasted for only 10 minutes, with a rule that each team must have the opportunity of possession at least once. Therefore, if the first team to possess the ball scored, the other would get a chance to either equalize or win the game. The winner was the team with the highest score after both teams had at least one possession. Sudden death applied if the score was even after each team had had one possession. If still tied after 10 minutes, the game ended as a tie. Only two games remained tied after overtime in WLAF/NFL Europe history: London Monarchs vs. Birmingham Fire in 1992, and Berlin Thunder at Hamburg Sea Devils in 2006. The score of both games was 17–17.
