Perfect Bracket

Try to predict the perfect March Madness bracket.

Build your perfect March Madness bracket — pick winners for every round from the First Four through the Final. The odds of a perfect bracket are roughly 1 in 9.2 quintillion if you flip a coin per game, around 1 in 120 billion if you pick favourites. No verified perfect bracket has survived the Sweet Sixteen. Pick anyway — the bracket maker handles the seeding and the auto-advancement, you just pick the winners.

Walkthrough

How this format works

A worked 8-team single elimination bracket. Win and you move right, lose once and your run is over.

Build one step by step

From an empty editor to a finished, printable perfect bracket bracket.

1
Add your teams
Type each team or player into the editor, or paste a whole list at once. Single elimination works for 4 up to 64 names.
2
Set the seeding
Order matters. Seed 1 should be your strongest team. The editor pairs seed 1 against the bottom seed, 2 against the next, so the top two can only meet in the final.
3
Generate the bracket
Hit Generate. If your team count is not a power of two, the top seeds get first-round byes automatically so the bracket still ends with one champion.
4
Score the games
Type a score into each match. The winner advances to the next round on its own, all the way to the final.
5
Print or share
Pick landscape or portrait, then print to PDF. Or save the bracket and share the link so everyone follows along.

About

About this format

Every March, millions of Americans fill out an NCAA bracket. Roughly one in 13 brackets in the Capital One challenge survives the first round each year; only a handful of brackets are ever still perfect at the Sweet Sixteen, and none have been verified perfect past it. Warren Buffett's billion-dollar perfect-bracket challenge has been running since 2014 with no winner — the closest brackets have busted in the second round. This page is the bracket maker pre-configured for the NCAA Tournament shape: 68 teams in the First Four, knocked down to 64 in the Round of 64, then 32 → 16 → Elite Eight → Final Four → National Championship. Pick winners by clicking, score games as they happen, and your bracket updates round by round. Same maker handles your office pool, your group chat, your shot at the Bilas / Lunardi / KenPom-beating perfect bracket.

FAQ

Frequently asked questions

Has there ever been a perfect bracket?

No verified perfect bracket has ever survived past the Sweet Sixteen in any major bracket challenge (NCAA, ESPN, Capital One, Yahoo). The longest verified perfect bracket was Gregg Nigl's in 2019, which survived through 49 straight correct picks (mid-second round) before busting on Purdue beating Tennessee.

What are the odds of a perfect bracket?

Roughly 1 in 9.2 quintillion (9,223,372,036,854,775,808) if you flip a coin for every game. Closer to 1 in 120 billion if you only pick favourites, and around 1 in 2 billion if you're a college-basketball expert using KenPom-style models. Either way, longer odds than winning the Powerball multiple times in a row.

Are there any perfect brackets left this year?

Statistically, almost never past the Round of 32. Out of 20+ million brackets entered across major contests in a typical year, the count of still-perfect brackets is usually zero by the end of the first weekend. ESPN's tracker publishes the live count.

How does this bracket maker differ from ESPN / CBS / Yahoo?

Those run a single contest with shared scoring rules. This one is your bracket — fill it out for your office pool, your group chat, or as a personal pick sheet. Print it, share the link, and update it as the tournament runs. No login, no contest entry, just the bracket.

Can I print my picks to fill in by hand instead?

Yes. Open the editor, hit Print without picking any winners, and you get a blank 64-team NCAA-shape bracket on one page. Fill it in with a Sharpie.
