Tasukuea (from Japanese, literally "find squares") is a type of logic puzzles. It is played on a rectangular or square grid with numbers or question signs in some cells. The goal is to blacken some cells of a grid according to the following rules: - Cells with numbers or question signs cannot be blacken. - Black cells form square areas that must not be orthogonally adjacent. - A number in a circle indicates the total number of black cells in areas orthogonally neighbouring the numbered cell. - A cell with a question sign must have at least one adjacent black cell. - All the white cells must be connected horizontally or vertically. puzzle games for adults - puzzle game for adults - puzzle game book - puzzle game adult - puzzle game brain teaser - puzzle game gift - jigsaw puzzle games - logic game book - logic game puzzles - logic games for adults - math games - math game adult - math game books - brain games - brain games for adults - brain game books - brain game puzzles - brain game adults - brain game books for seniors - brain game for adult - brain game large print
