Microsoft introduced a new feature on Xbox One recently called Xbox Quests. Xbox Quests, when completed, give you a guaranteed reward and also automatically enter you into a draw to win a Samsung 55″ QLED television. So basically, just by playing games, you can win more games and even a new display for that sleek new Xbox One X.

Hopefully Microsoft starts many offers like this in the future because it will encourage gamers to use their services. One of the main reasons I use Bing is because I can earn Xbox Live Gift Cards so I can buy more games. The points are also allotted rather generously so it works out well.
