Log on to the Xbox Live Marketplace from your 360 game console. Press the "directional pad" buttons on your game controller to browse the "arcade" tab for special offers for games and content available for purchase with Microsoft points. Many special offers include discounts for older titles or a bonus of free Microsoft points with the purchase of a specific title. An example is a recent offer to obtain 400 or 1,200 free points with the purchase of "Limbo", "Lara Croft", "Hydro Thunder", or "Castlevania" by August 31, 2010. Check the Xbox Marketplace frequently for current promotions featuring free points.
Create a secondary e-mail account to register with a third party survey site such as Freemicrosoftpoints.org. Follow the registration steps required to complete surveys to earn free points. You will earn survey points for each survey you complete. Follow the instructions on the site to convert survey points to free Microsoft points once you have earned at least 200.
Create an alternate gamer tag to use on Xbox Live if you choose to boost other players. Boosters advertise their services by playing games using gamer tags such as "MrRentAKill" and "xXBoostALotXx." Many players will actually initiate contact with the "booster" and offer free points for intentionally losing games so that they can improve their gamer score and leader board records. Although boosting is very common on Xbox Live, it is important to note that this is considered cheating and not acceptable by Microsoft if substantiated.
