Sling TV is now allowing new customers who own Roku devices to watch free episodes of select shows without a subscription, or even setting up an account.

The feature, which was added yesterday, and is expected to be offered on non-Roku devices soon, is designed to entice consumers to give Sling a try, and sign up for a subscription if they like what they see.

If you click on the ‘Browse As a Guest’ in the Sling TV app on Roku, you can now watch a single episode of such shows as Showtime’s The Affair, Ray Donovan, Billions and Shameless, and HDNet’s The Big Interview With Dan Rather, among many others.

In addition, you can purchase certain a la carte channels such as Showtime and the NBA League Pass without subscribing to Sling TV’s base package, which costs $25 a month.

“We’re giving Roku users who are new to Sling TV the ability to experience Sling without subscribing to programming or entering in any payment information,” Sling says on a company blog.

Sling has two base packages: Sling’s Orange plan starts at $25-a-month and includes ESPN and roughly 30 cable networks. The Blue package costs $25-a-month, and includes more than 40 channels including live network feeds in select markets as well as several Fox channels. You can have both plans for a combined $40 a month.
