What a run it was.

After 40 games in the NCAA tournament, the final perfect bracket has busted.

This includes reporting on tens of millions of brackets from the Capital One March Madness Bracket Challenge game at NCAA.com, as well as games at Bleacher Report, CBS, ESPN, Fox Sports and Yahoo.

The record-setting bracket, entered in Yahoo’s bracket game, was the only bracket to make it past 37 games unscathed, and managed to reach 39 straight correct picks before Iowa State fell short of a comeback against Purdue and handed the bracket its first loss of the tournament.

For reference, the odds of flipping a coin and having it land on heads 39 times in a row is 1 in 549,755,813,888.
