One A4 PDF, ready for the printer: 10 picture nonograms, a how-to-solve guide on the first page, answer key at the back. No signup, no email, no watermark.
A nonogram — also sold as picross, griddler, hanjie or Japanese crossword — is a logic puzzle played on a grid. The numbers along each row and column give the lengths of the runs of filled squares in that line, in order, with at least one empty square between runs.
That is the entire rule. When the grid closes, the filled squares form a picture — which is how you know you got it right before you ever look at the answer key.
You never have to guess. If you are stuck, there is a deducible square somewhere on the grid.
Those four rules with a worked example each, and the alien from this pack opened pass by pass until the picture appears: how to solve nonograms, step by step.
Stuck on a puzzle from somewhere else? Type its clues into the nonogram solver — it runs the same solver that signed off these ten, and it says which row or column makes the clues impossible when they are.
Rather not print anything? Five puzzles play right in the browser — fill, mark, and the picture appears when the grid closes: the free nonogram sampler on itch.io, no download and no account.
Making your own instead? Draw it in the nonogram checker — it counts the clues off your picture and then tells you whether the puzzle closes on logic alone, marking the cells that would force a guess. It is the same check these ten had to pass.
Five at 10×10 (★, to warm up), four at 15×15 (★★) and one at 20×20 (★★★). Each picture's name appears only in the answer key at the back, so nothing is spoiled before you solve it.
Printing these for a class? The ten sheets ranked by how hard they actually are — measured on the solver, not by grid size — plus a 45-minute lesson plan: nonograms in the classroom.
The classic defect in a printed nonogram is the puzzle that does not close on logic alone: at some point the human has to guess between two possibilities and backtrack if it goes wrong. That flaw is invisible in the PDF — it shows up on your kitchen table, half an hour in. Before any of these ten made it onto a page, a solver rejected the puzzle unless all three of these held:
A puzzle that fails is not patched by hand — it is thrown out. It is the same solver that runs over all 100 puzzles in the book.
This pack is free for personal use and for classroom use — a teacher may print it for a whole class. What you may not do is sell it or bundle it into another product.
These ten pictures were drawn for Pixel Logic vol. 1 and left over when the book filled up at 100 (40 at 10×10, 35 at 15×15, 25 at 20×20). This is not an extract: download the pack, buy the book later, and you pay for nothing twice. That is not a promise — the script that assembles this pack re-checks it against all 100 puzzles of the book on every build, by grid and by the word printed in the answer key, and refuses to write the PDF if the sentence stops being true.
The full book is 100 picture nonograms, all proven the same way, with the how-to-solve guide up front and an answer key naming every picture. A4 PDF, 115 pages, instant download, print it as often as you like.
