The Times Hashi (The Times Puzzle Books)

Description

After Su Doku, Hashi is one of the most popular Japanese logic puzzles in Japan. Hashi requires logic and reasoning, not mathematical ability. If you think Su Doku is addictive, you'll certainly enjoy the challenge of Hashi. A collection of 150 new puzzles of varying degrees of difficulty: 10 easy, 30 mild, 60 difficult, 40 super difficult, 10 super super difficult. Hashi means 'Bridge' in Japanese. In Hashi you must connect a series of circles (islands) containing numbers by lines (bridges) so that the islands form one continuous connected path. Easy enough? Well there are naturally some extra rules to make life a little harder: the bridges must be straight lines, running horizontally or vertically between the islands; they cannot run diagonally. The bridges cannot cross each other or any island. The number of bridges connected to each island is the same as the number inside the island and there can be a maximum of two bridges between any two islands.
