• Elite Eight: March 25-26
• Final Four: April 1
• NCAA championship game: April 3 

The March Madness bracket and matchups were revealed on Sunday, March 12. Alabama, Houston, Kansas and Purdue were listed as the top seeds in their respective regions. In a stunning upset, Purdue was eliminated in the first round by No. 16 seed Fairleigh Dickinson, on Friday, March 17.

The full, updated bracket can be found on the NCAA’s website. 

With 68 teams invited to the Big Dance, the NCAA holds four play-in games to get the field down to 64. After that, the math works out to have four regional tournaments of 16 teams each. The winners of the four regional tournaments then advance to the Final Four, held this year in Houston.

March Madness began Tuesday, March 14, with two play-in games followed the next night by two more play-in matches. After those First Four games, the field of 64 was set and the tournament began in earnest with a full slate of games on Thursday and Friday, March 16 and 17. All 64 teams played and half were eliminated. This weekend features the winners of those games. Whoever triumphs moves on to the Sweet 16 next week.

As in past years, the tournament is being shown across four channels: CBS, TBS, TNT and TruTV. Only one remaining game is on TruTV, but it’s a big one: Sunday’s matchup between Florida Atlantic and Fairleigh Dickinson University, the team that knocked off Purdue.

If the last time you watched something on TruTV was last March, then you might need some assistance finding it for this year’s tournament. Here’s a handy guide for some of the major cable or satellite TV providers:

• Dish Network: 242
• DirecTV: 246
• Verizon Fios: 683
• Xfinity: varies by location (search by street address and ZIP code)
• Spectrum: varies by location (search by street address and ZIP code)

The Final Four and national championship game will air on CBS and stream on Paramount Plus. 

Go to the NCAA’s March Madness Live site or use its March Madness Live app and you’ll be able to watch games for free. You can watch March Madness Live on iOS and Android devices along with Apple TV, Roku, Fire TV and Xbox One. The app also supports AirPlay and Chromecast.

As with most things that are free, there’s a catch. Without proving you’re a pay-TV subscriber, you get only a three-hour preview, after which point you’ll need to log in to continue watching.
