The program is SO close — find the one broken step and fix it to reach the goal!

What does Bug Hunt teach?

Bug Hunt is a coding game for 2nd grade – 5th grade that practises debugging. Like every TernQuest game it is tied to a skill on the curriculum map (state standards — Common Core, NGSS, CSTA and History–Social Science, PK–5), and Pip the tern gives hints, never answers.

Is it free?

Yes. Bug Hunt is playable in the browser with no ads and no signup. A free account (one child) saves progress and stars.
