What does Tower Stacker teach?

Tower Stacker is a math game for 2nd grade – 5th grade that practises recursive planning (tower of hanoi). Like every TernQuest game it is tied to a skill on the curriculum map (California Common Core, PK–5), and Pip the tern gives hints, never answers.

Is it free?

Yes. Tower Stacker is in the free tier, playable in the browser with no ads and no signup. A free account (one child) saves progress and stars.
