Offerpal Media announced today that it is bringing its offer platform to Outspark, a portal that combines free to play games with “personalized social experiences.”

Outspark will now enable its 4 million users to purchase SparkCash by participating in sponsored offers. Users can then spend their SparkCash in any of Outspark’s games, like Fiesta, Wind Slayer, and Project Powder. Outspark has garnered its greatest usage from users 15-25 in the United States and Europe.

Offerpal recently also announced a new partnership with Aeria Games (creators of titles such as Last Chaos and Shaiya). Aeria caters to around 5 million players who are offered their own unique virtual currency dubbed “Aeria Points.” Much like SparkCash, players can earn Aeria Points by participating in offers.

Incentivized virtual currency is proving to be an increasingly successful way to monetize social applications. Because players don’t have to go through a payment flow, incentivized offers from leading managed offer providers like Super Rewards, Peanut Labs, and Offerpal give more players access to more virtual goods and thus they return to play more often – and that’s a good thing for developers and advertisers.
