With 68 teams invited to the big dance, the NCAA holds four play-in games to get the field down to 64, after which point 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 begins on Tuesday, March 14, with two play-in games followed by two more play-in games the next night. After these First Four games, the field of 64 is set and the tournament begins in earnest on Thursday, March 16, with a full slate of games that will take place all afternoon and into the night with at least a few moments of madness practically guaranteed.

The March Madness bracket and matchups will be revealed this Sunday, March 12. Selection Sunday begins at 6 p.m. ET (3 p.m. PT) on CBS.

Here’s the schedule, round by round:

• First Four: March 14-15
• First round: March 16-17
• Second round: March 18-19
• Sweet 16: March 23-24
• Elite Eight: March 25-26
• Final Four: April 1
• NCAA championship game: April 3 

As in past years, the tournament will be shown across four channels: CBS, TBS, TNT and TruTV. Yep, the time has come again to find TruTV on your dial.

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.
