Let’s not waste any time. The bracket is here. March Madness is here.

Presenting the 2017 NCAA tournament bracket

Villanova, Kansas, North Carolina and Gonzaga all locked down No. 1 seeds when the NCAA tournament bracket was announced Sunday night. Duke landed a No. 2 and Northwestern, going dancing for the first time ever, landed a No. 8. (Syracuse, by the way, found itself as a 1 seed in the NIT).

Take a look at our interactive bracket before the chaos starts Tuesday with the First Four. If you're after an hour-by-hour, day-by-day breakdown of Thursday and Friday -- the first full days of the tournament and maybe the best two days in sports -- we have you covered there, too. And if you're old school, you can always print out your bracket. That works.

Play the NCAA Bracket Challenge Game

With the field filled out, it’s time for you to make your picks in the official bracket game of the NCAA tournament, the Capital One March Madness Bracket Challenge.

BRACKET CHALLENGE GAME

The Madness is underway.
CHECK YOUR BRACKET
Brackets lock in Thursday at noon ET, so you only have a few days to set up (or join) a group and get picking. 

Our Bracket Beat page has tons of tips on picking.

10 takeaways from the bracket reveal

Spoiler alert: The East is loaded. No. 1 seed Villanova, 2 Duke, 4 Florida, 5 Virginia and 8 Wisconsin. That’s chaos in the making.

Also, as much fun as the first weekend is bound to be, potential pairings down the road offer some enticing rematches: Kansas-Iowa State, UNC-Kentucky, Arizona-Gonzaga. Yes, please.

NCAA.com’s Mike Lopresti goes into detail on some of the biggest storylines of the bracket. And explore 2017’s tournament field by the numbers while you’re at it.

The Madness Matchup Tool — here to help

We compiled data from every NCAA tournament game played (not including the First Four or play-in games, for seed purposes) since the field expanded to 64 teams in 1985. Through the end of the 2016 tournament, there have been 2,016 such games.

The Madness Matchup tool compares historical win percentages in five categories -- the seed, conference, final AP ranking (once it's released Monday), mascot and color.

Use the tool to see how any two tournament teams will match up.
