HSK Study Studio

Original printable Mandarin / New HSK study materials and logic-puzzle packs for English-speaking teachers, tutors, and homeschool families. Free-sample-first storefront (no email gate on freebies). Materials are unofficial and not affiliated with CLEC/CTI. Some English glosses/instructions were drafted with AI tools and checked by me (native Mandarin speaker). Puzzle packs use deterministic procedural generation + exact solvers, not generative AI graphics.
