If you only need a few more Play credits to buy that game or rent a movie, then you might be interested in a new app simply called Google Opinion Rewards. Just as its name suggests, all you have to do to earn credit is to answer a weekly survey with up to ten questions each. Of course, you'll have to enter in your Google Wallet credentials first so that it'll know where to send that money. As for what sort of questions you may expect, Google is partnering up with a variety of researchers from brands like P&G, Lowes and Priceline who need public insight on topics like the best promotional campaign or what sort of cars you might be interested in. Sure it takes awhile to answer a few questions and you'll be an inadvertent pawn in a corporate marketing strategy, but you'll soon forget all that once you get to the next level in Candy Crush.
