The NCAA Division I men’s college basketball championship, better known as March Madness, will consist of 67 single-elimination games played over the next 21 days, between March 13th and April 2nd. All games, including tonight’s Selection Show which starts at 6 pm ET, will be available to stream live through an Amazon Fire TV, Firestick, and Fire TV Edition television. Here’s how to watch all the live coverage and which apps you’ll need.

If you have a cable subscription

CBS, TBS, TNT, and TruTV will each broadcast some of the games. If you want to watch all 67 games, you will need access to all of these networks. Watching TBS, TNT, and TruTV games is easy because they will all be available through the March Madness app. Just activate it with your TV provider and you’ll be able to watch all but the CBS games from that one app. Alternatively, you can install the TBS app, TNT app, and TruTV app and watch through those apps instead of the March Madness app. Of course, those apps also need to be activated with a TV provider.

Unfortunately, the CBS app cannot be activated using a TV provider like the other three apps. One option is to use Firefox or the Silk Browser to watch CBS games on the March Madness Live website. Otherwise, you’ll need to subscribe to CBS by paying $5.99 per month with ads or $9.99 per month without ads for access to the CBS games through the CBS app.

If you don’t have a cable subscription

If you don’t have a cable subscription and don’t want to pay anything, your only option is limited viewing through the March Madness app. Without activating the app, you’ll be able to watch 3 hours of live games for free before you’re cut off.

Otherwise, your best option is to use one of the streaming TV services to watch on a Fire TV device.

Sling TV

Sling TV will let you stream TNT and TBS games through their app if you subscribe to their $20 per month plan which comes with a 7-day free trial. To get access to the TruTV games, you’ll need to bump your subscription to the $25 per month Sling Blue plan. Since CBS is not available on Sling TV, you’ll need to subscribe to it separately for $5.99 per month and watch those games through the CBS app.

DirecTV Now

DirecTV Now offers CBS, TNT, TBS, and TruTV through their app for $35 per month and it includes a 7-day free trial.

Hulu with Live TV

Hulu offers CBS, TNT, TBS, and TruTV through their app for $40 per month and it includes a 7-day free trial. A Hulu subscription will also allow you to activate the March Madness app.

PlayStation Vue

PlayStation Vue offers CBS, TNT, TBS, and TruTV through their app for $40 per month and it includes a 7-day free trial. A PlayStation Vue subscription will also allow you to activate the March Madness app.
