The Xbox Live Rewards Program hasn’t been especially robust as of late, but Microsoft seems to have changed that with their new Gamer IQ Trivia Challenge program which began earlier today. Rewards members are given the opportunity to answer trivia questions which enter them in a daily instant win contest rewarding 100-1000 Microsoft points, a weekly sweepstakes rewarding 4,000 MSP, and grand sweepstakes rewarding 10,000 MSP. New questions are available every day until May 15, so Xbox Live members should join the Rewards program and visit the Gamer IQ page daily for multiple chances at heaps of Microsoft Points.

In addition to these sweepstakes, Microsoft is offering a free Halo Banshee avatar item for 200 or more points spent in the Xbox Live Marketplace and 400 points free with the purchase of the Halo: Reach Defiant Map Pack or Games on Demand version of Halo: Reach. Both of these offers are valid until the end of the sweepstakes period – May 15, 2011.
