TechRewards uses a gamification model to create a fun, inventive and competitive environment for all technology enthusiasts to learn about Microsoft platforms. Users can earn badges, experience points (known as "XP") and redeemable points (known as "Pts") by completing quizzes and challenges. Users could then redeem their hard earned Pts for any reward of their choice from a wide array of exciting items put together in our reward catalog.
