Has an AFL game ever ended 36-33?
Exactly once. On July 12, 1902, Melbourne beat Carlton 36-33, and no AFL game before or since has ended that way. When it happened it was a scorigami, the first 36-33 in league history.
That makes 36-33 the 3836th most common final score out of 6,607 that have ever occurred in AFL. One point away, 37-33 has happened 2 times and 36-34 has happened 1 times.
