For a parent or grown-up

Maths and computational thinking, traced together.

Each puzzle is a small program. A child follows it with a pencil, updates the numbers, notices patterns and checks what happened step by step.

✓ Children can play without an account or personal details. The adult email preview is separate from play and does not unlock a reward.
