100 Puzzle Games: Hashiwokakero Puzzles

(from Japanese "Hashi o kakero"; literally "build bridges"; also known as "Hashi", "Bridges", "Chopsticks" or "Ai-Ki-Ai") is a type of logic puzzle. It is played on a rectangular grid with no standard size, although the grid itself is not usually drawn. Some cells start out with (usually encircled) numbers from 1 to 8 inclusive; these are the islands. The rest of the cells are empty.The goal is to connect all of the islands into a single connected group by drawing a series of bridges between the islands. The bridges must follow certain criteria:• They must begin and end at distinct islands, travelling a straight line in between. • They must not cross any other bridges or islands. • They may only run orthogonally. • At most two bridges connect a pair of islands. • The number of bridges connected to each island must match the number on that island. 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
