About Hana
Hana Yoshida writes the analysis content for Nonocross Answers. She has been solving nonogram puzzles since encountering them in Japanese puzzle magazines and became interested in the logic structures that make picture-cross puzzles uniquely solvable without trial and error.
Her work on this site covers 60 levels: each level page includes an entry-point analysis, a row-by-row logic breakdown, and density statistics derived from the verified binary grid data. The strategy guides on the Tips & Logic and How to Play pages are also her writing.
Hana focuses on making solve logic accessible to players who are stuck rather than just providing answers. The row notes on each level page are written to explain why a cell is filled or empty, not just which state it is.
