Logic Games For Boys : Stostone Logic Puzzles With Answers

Stostone ("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. brain teasers for kids ages 10-12 - brain teasers for kids - brain teaser games - brain teaser puzzles for kids - brain teaser books for kids - brain teaser for kids - brain teaser for teens - brain teaser for kids ages 8-10 - brain teaser games for kids - brain teaser games for kids ages 10-12 - brain teaser gifts - brain teaser travel games for kids
