San Francisco-based mobile advertising platform Tapjoy has partnered with LINE to bring its Interplay ads to the messenger service.

Users will be able to earn LINE Points by watching rewarded ads from Tapjoy, which can then be used to purchase stickers and themes for the messaging app.

The partnership gives Tapjoy and its clients access to LINE's 220 million active users across 200 countries.

Helping people get closer

"LINE has become one of the most popular apps in the world by helping people get closer to one another and by delivering a top-notch communication experience," said Steve Wadsworth, president and CEO of Tapjoy.

"Our Interplay ad platform is already the method of choice for millions of consumers to access premium content in their favourite apps, and we are excited to bring our platform to millions more people worldwide through this partnership with LINE."

Most recently, Tapjoy found the secret to having your push notifications seen by the most people – by sending them on a Monday lunchtime with the phrase "get your" in the text.
