Make printable nonogram puzzles from original geometric pictures, a seeded pattern or your own binary grid. Choose five, ten or fifteen cells per side and include a separate answer sheet when useful.
Preview is scaled to fit. The PDF keeps the exact dimensions.
A nonogram turns a hidden picture into ordered run clues. A row marked 2, 3 contains two filled cells followed later by three filled cells, with at least one empty cell between the groups. The same rule applies down each column. Read both directions together: neither clue list alone describes the whole picture.
This editor accepts binary grid rows, not photo uploads. Reduce your idea to occupied and empty squares yourself, then enter the rows. A small silhouette usually communicates more clearly than a detailed scene at fifteen cells per side.
Different pictures can share the same run clues. The editor rejects a custom grid when the clues admit more than one solution, and separately reports a verification limit. Change a few cells or use a smaller picture before trying again.
Yes. A valid custom bitmap has exactly one solution from its printed clues, so the completed grid on the answer page matches the submitted occupied cells. The clue order follows the picture from left to right and top to bottom.
The five-cell grid is a compact introduction to crossing row and column information. Ten cells provide more room for a recognizable geometric image, while fifteen cells produce a denser sheet with longer clue lists. A larger grid is not automatically harder. The number and arrangement of runs matter more than the area alone, so review the actual puzzle before choosing it for a learner.
Diamond, house and tree are original binary patterns. The seeded picture option creates another arrangement from the variant number, and the same settings reproduce it. The generator retries pictures that do not pass its uniqueness check; a geometric fallback can be used when required. This makes the seed a reproducible identifier, not a certified difficulty level. For another number-grid activity, try printable Sudoku.
