Microsoft is looking to give a boost to its library of free-to-play titles on the Xbox One with the aptly named FREEdom Rewards campaign. Open to Xbox Live Rewards members, FREEdom Rewards essentially gives you a shot at winning prizes for checking out games like Roblox, Neverwinter, and Warframe.

Roblox Freedom Rewards

At the moment, the biggest prize of all is up for grabs for playing Roblox. For every 30 minutes you play the game through February 28, you get another entry (up to 4 per week) to win a 4K Samsung TV, a wireless gaming chair, or a gaming headset. Other games, like Neverwinter, World of Tanks, and Star Trek Online will reward you with a small in-game item or items for referring friends. Meanwhile, spending money on in-game items and add-ons will earn you Rewards Credits.

The current campaign has 42 days left as of this writing, so there's still plenty of time to get in. Be sure to hit up the FREEdom Rewards site for the full skinny on what's up for grabs and to join Xbox Live Rewards to participate.
