Not counting the original 0-0 score, how many times will the game have a tie score?
(For example, the correct answer for Super Bowl 50 would have been 0; the correct answer for Super Bowl 49 would have been 2, as it was 7-7 and then 14-14. Note that if one team were ahead 13-7 and the other team scored a touchdown, the game would be tied 13-13 pending the point after. But if one team were ahead 10-7 and the other team scored a touchdown, at no point would the game be tied 10-10.)
