Geometry Puzzles: Shakashaka Puzzles - The Best Japanese Puzzles Collection (Logic Puzzle Books)

Shakashaka (also known as "Proof of Quilt") is a logic puzzle, invented by Nikoli. The task is to place one of the four isosceles right triangles in some white cells. Each triangle must occupy exactly half of its cell, but may be in one of four orientations. Every contiguous white region must be a rectangle or a square. A number in a black cell indicates how many triangles are adjacent to that cell by sides. logic puzzles for adults - logic puzzle books for adults - logic puzzle book - logic puzzle games - logic puzzle for adults - logic puzzle activity book - logic puzzle adult - logic puzzle grid - logic puzzle magazine - logic puzzle magazine for adults - logic puzzle workbook - logic puzzles for middle school - logic puzzle answers - logic puzzle books for middle school - logic puzzle brain teaser - logic puzzle beginner - logic puzzle daily - logic puzzle for middle school
