Nonogram picture puzzle books for Amazon KDP & Etsy

A picture logic puzzle, also called Hanjie, Griddlers or Paint by Numbers. The numbers beside each row and above each column give the lengths of the blocks of filled squares in that line, in order, with at least one empty square between blocks. Filling the squares by logic reveals a hidden picture.

Yes. A solver works every puzzle out with the logic of its difficulty before it is printed. Some pictures would allow two answers from the numbers alone; then a few squares are printed as givens, so the solver — and your reader — always reaches the one picture.

The logic each level needs. Easy and Medium are solved line by line, comparing the numbers of one row or column with what is already known; Easy books take the simpler pictures. Hard puzzles may need trying a square and spotting the contradiction it leads to. Bigger grids make every level longer.

From a library of 330+ pictures drawn for print (Animals, Nature & Weather, Food & Drinks, Travel & Transport, Home & Everyday, Sports, Music & Hobbies, Space & Fantasy, Christmas, Halloween, Easter, Valentine's Day, Thanksgiving, New Year), from abstract symmetric patterns made from the book code, or from your own images and drawings on the Publisher plan.

Nonograms have no words: the title, the instruction and the difficulty line follow the book language.

Starter and Pro books are printed in English.
