For most teams in the men’s and women's NCAA basketball tournaments, six wins stand between them and a national championship.
But for some, an extra victory is required.
A total of eight teams from each tournament field have to earn their way into the Big Dance’s Round of 64 by playing in the First Four.
The First Four was introduced to the men's tournament in 2011 and has seen two teams make it from there all the way to the Final Four: VCU in 2011 and UCLA in 2021. Last season was the first time the women's tourney featured the First Four.
So, could we see a First Four squad make a Cinderella run this year?
Here’s what to know about the opening games of March Madness:
