Picross, Griddlers, Nonograms, Hanjie Book - Chad Walker - Bog

Picross, also known as Hanjie or nonogram, is a logic game that consists of blackening the squares of a grid in order to reveal an image.
To achieve this, numbers are shown on the left and top of the grid. Each number indicates the number of consecutive squares in the row or column that must be blackened. Each group of blackened squares is separated by at least one white square.
This book contains 45 previously unpublished Picross grids of various levels.
