| Publisher Description: Stone on Stone is a logic puzzle invented by Nikoli. A rectangular or square grid is divided into regions. The goal is to blacken some cells of a grid ("stones") according to the following rules: - All black cells in a region must be connected horizontally or vertically. - A cell with a number indicates how many cells in the region must be blackened. - In regions without a number any amount of cells may be blackened (at least one). - When two cells are orthogonally adjacent across a region boundary, at least one cell must be white. - If all stones "fall down", they must cover exactly the bottom half of the grid. logic puzzle - logic puzzle books for adults - puzzle books logic - adult logic puzzle book - logic puzzle game - logic grid puzzle books - logic stacking puzzle - math puzzle books for adults - puzzle math - math puzzle games - math jigsaw puzzle - math puzzle book - math puzzle for adults - math puzzle adult |
