The NCAA Tournament always brings about the dream of a perfect bracket filled out for March Madness. It's a dream, to be sure, because the odds of that actually happening are truly astronomical. For reference, there is a 1-in-9,223,372,036,854,775,808 of someone filling out a perfect bracket, getting all 63 picks correct. That's exponentially less likely than the odds of being eaten by a shark while being struck by lightning (1-in-40,000,000,000,000,000).
Games like Saturday's Round of 32 clash between John Calipari and Rick Pitino as No. 2 seed St. John's took on No. 10 seed Arkansas is a big reason as to why it's nearly impossible to achieve the perfect bracket.
On Sunday in the second day of Second Round action, there were no huge upsets early with the two No. 1 seeds in action, Duke and Florida, getting their wins — though UConn certainly tried to make it happen and pushed the Gators to the brink.

What we don't know is if this is the same bracket or the same person, but out of the tens of millions of brackets that were filled out and submitted, there's only one that hasn't missed a game so far in the NCAA Tournament.
As for what's next for the remaining perfect bracket, they have some landmines to avoid, according to ESPN. That bracket has No. 6 seed Illinois takiing down No. 3 seed Kentucky in the Round of 32 before they have No. 2 Alabama getting past Saint Mary's. If they survive that, then they will be cheering hard for No. 4 seed Maryland against cinderella candidate No. 12 seed Colorado State.
Which games eliminated the most perfect brackets in 2025 March Madness?
The first game of the 2025 NCAA Tournament between No. 9 seed Creighton and No. 8 seed Louisville appears to be the biggest eliminator of perfect brackets according to the data provided by ESPN, taking out more than 13 million brackets on their service, more than half of the number that were submitted.
Not far behind, though, was the No. 12 McNeese upset of No. 5 Clemson in the First Round, an upset that took down 6.6 million perfect brackets. Speaking of that, everyone was ready to fade Purdue as their No. 4-over-No. 13 seed win over High Point was the third-biggest eliminator, taking down over 2.1 million perfect brackets.
