Instructions
1
Redeem any Xbox Live trials that come with your console system. Many systems now come with up to three 1-month trials. To redeem, your gamertag must be new. Simply choose to buy a new Gold membership when you log on, and click the link to redeem the free trial.

2
Purchase games that contain free trial codes. These specially marked games will be Xbox Live compatible (such as Star Wars Battlefront) and include a code that must be redeemed online. Redeem by completing your new gamertag registration and entering your free trial code.

3
Complete surveys and offers that allow you to redeem your "winnings" for Xbox Live points. Websites such as Gaming Lagoon and Boxed Deal will occasionally offer Xbox Live incentives.

4
Enter contests on gaming sites and blogs to win Xbox Live memberships. Sites such as https://www.online-sweepstakes.com keep a list of which sites are currently running gaming contests and links to enter.
