About Nonocross Answers
How the grids are sourced, verified, and presented
What this site is
Nonocross Answers is a reference database for the Nonocross picture-cross puzzle game by Gimica GmbH. This site documents 60 solved levels, from Level 1 through Level 60, with fully solved grids, clue listings, logic entry points, and row-by-row solve notes.
The goal is to provide the most accurate nonogram answer data available: not screenshots or transcribed answers, but programmatically derived grids cross-checked against in-game clue data.
This site is not affiliated with, endorsed by, or in any way officially connected to Nonocross or Gimica GmbH. All game content, puzzle names, and imagery belong to their respective owners.
Data methodology
Binary grid extraction
Each level's solution is encoded as a flat binary array (0 = empty, 1 = filled) in the game's web interface. We extract this array as the primary source of truth for every grid.
Clue derivation
Row and column clues are derived algorithmically from the binary grid - not transcribed from the displayed clue list. We count consecutive runs in each row and column to build the verified clue set.
Cross-check verification
The derived clues are compared against the HTML clue spans in the source page. If they disagree on any row or column, the level is flagged and rejected from the database until the discrepancy is resolved.
Render & publish
Verified grids are stored as structured JSON and rendered server-side as CSS grid layouts. No images - the grid you see is built from the same binary data as the original solution.
Coverage & statistics
The team
Content analysis and solve documentation is handled by Hana Yoshida, a nonogram enthusiast with a background in logic puzzle design. Data collection, cross-checking, and site infrastructure are maintained by the site's technical team.
