Triangle nonogram puzzle books for Amazon KDP & Etsy

A black and white nonogram in which a square may also be half filled, cut along a diagonal: ◢ ◣ ◤ ◥. The row and column clues list numbers — blocks of full squares, as in a classic nonogram — and triangles, each one half square of that shape, in order. Solved, the grid shows a picture with smooth diagonal edges. Triangle nonograms come from Slovak puzzle magazines; in English they are also called trianograms.

Two blocks of full squares still need at least one empty square between them. A triangle, though, may touch a block or another triangle — even one of the same shape — or stand apart. A square can only hold a triangle when both its row and its column list that triangle, which gives the solver new ways to reason.

Yes. A solver works every puzzle out with the triangle rule and the logic of its difficulty before it is printed. If the clues alone would allow two pictures, a few squares are printed as givens, so the solver — and your reader — always reaches the one picture.

Telling four kinds of triangles apart and placing them without gaps is a step up from classic nonograms, so triangle books come in the Standard and Senior (large print) editions. For children, make a Kids nonogram book instead.

Yes. Upload PNG, JPEG, WebP or GIF images or draw in the pixel editor: the image is converted into black and white squares in your browser, every inner corner becomes a half square, and the puzzle is checked for one solution with the triangle rule. Use only images you have the rights to.

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

Starter and Pro books are printed in English.
