four by four, no repeats in sight—this little grid sings when every number lands just right 🎵
the 2×2 constraints create great stepping stones. slow start, then the whole grid clicked into place.
love the tiny code-like thrill of watching every row, column, and box compile cleanly ✨
instant-invalid feedback makes the loop snappy, while the 2×2 boxes keep the deduction nicely layered.
