Social advertising and analytics company Sometrics reports that it dispensed over 1 trillion virtual currency credits (dollar equivalent undisclosed) to gamers in the past year, and that its ad network reaches more than 100 million users in 228 countries.

Sometrics says it's advertising to those gamers and awarding in-game cash through Offer Solution, which allows publishers to give out virtual currency for free-to-play games when players participate in offers and surveys (e.g. trial subscriptions, downloading applications).

Offer Solution and the company's products are integrated in hundreds of titles -- social games, MMOs, and virtual worlds -- from publishers like Playdom, LOLapps, IMVU, K2, NHN, and more. Its products provide an inventory of over 7,500 advertiser-based offers.

The firm also recently launched Payments Manager, which enables publishers to manage payment options and multiple offer providers from a single dashboard; and Shop & Earn' Shopping Feed, which allows users to earn virtual currency for social games and apps when they make online purchases from Sometrics's retail partners.

"A year ago we made a deliberate shift in our business to capitalize on what we saw as an emerging trend toward using virtual currency as a way to generate real revenue for publishers of online games and virtual worlds," says Sometrics co-founder and CEO Ian Swanson. "We’ve been able to adapt as new needs arise and user behaviors evolve. Our success shows that we’re on the right track."
