The Profi-Nonogram Volume 3, Issue 12 contains three editions of the Profi-Nonogram magazine from Küng Verlag bound together. In total, this volume includes 72 black-and-white nonogram puzzles in a larger format. This visual puzzle is also known as Pic-a-pix, Hanjie, or O Ekaki. Nonograms offer more than just typical puzzles: they are also small works of art, as each solved puzzle reveals a picture. You become the artist while solving them. The numbers around the puzzle grid indicate where the areas to be colored are located. This is easy to explain but can be quite challenging. Additionally, this collection includes 12 mosaic puzzles. Profi-Nonogram Volume 3, Issue 12 features the issues Profi-Nonogram No. 35, 36, and 37.
