Viggle

Viggle is a rewards program where you accumulate points by checking into television shows, answering questions about the shows, or watching ads.  The rewards program is accessed through an app that is available in the Google Play store or the Apple App store.  The points accumulated can be redeemed for a variety of gift cards.

As of 7/31/2013 the gift cards below are available.  The availability of gift cards changes daily.

$25 Best Buy for 62,500 points
$25 Foot Locker for 50,000 points

Based on the gift card redemption each point is worth $0.0004 or $0.0005.  It is relatively easy to accumulate at least 400 points a day.  Accumulating points is easier if you have a DIRECTV account because they are several bonus point offers for DIRECTV account holders.

There are several limitations on the number of Viggle points that you can accumulate.  You may not accumulate more than 6,000 total points in a day (this includes points for games and ad engagements).  You may not accumulate watch or check-in bonus points for checking into more than 12 hours of television per day. If you have reached 720 watch points for the day, you will stop getting watch and check-in bonus points. A day is considered 12 am to 11:59 pm ET. Any points that are issued to your account after midnight ET (even if the check-in occurred the previous day) count toward the current day.

Other than rewards you receive in sweepstakes or instant win games, you may not receive more than $550 in rewards in a calendar year.
