Nonograms are picture logic puzzles known by many names, such as Griddlers , Picross , Japanese Hanjie Puzzles and Paint by Numbers . Using logical reasoning and the numerical clues offered, you color specific cells in a grid and – if correctly done - a hidden image will gradually reveal itself. The two-color variant in this book builds upon the classic black and white Nonograms by introducing 2 fill colors. This allows for a greater variety in logical strategies to apply and results in more detailed images. This book offers 101 such puzzles, ranging from small and easy (15 x 30 cells) up to much larger and harder ones (50 x 50 cells), which may require several hours of puzzling fun to fully resolve. Each puzzle will unveil a fun image of a cartoon character . The introduction provides an overview of possible strategies to apply and the solutions to all puzzles can be found at the very end of the book.
