Pierce County Library’s Teen Summer Challenge offers teens a one-of-a-kind way to explore their interests, library and community, now through Aug. 31.

Teens complete activities to earn badges like Code an App, Doctor Who, Hunger Games, John and Hank Green and Stop Motion Animation. New badges are released throughout the summer as participation increases. As of last week, more than 10,000 activities had been completed. Players share their experiences online and with other teens through regular community meet-ups.

Anyone 13 and older can register. Participants with a Pierce County Library card qualify for prizes. Each completed activity equals another entry into a grand prize drawing for an iPad mini. Top point earners win an Amazon gift card. Prizes are courtesy of Pierce County Library Foundation.

This year’s theme is Spark a Reaction. Activities and badges focus on learning in STEM (Science, Technology, Engineering and Math).
