Hashi: The Bridges Puzzle

This is a very good book of Hashi puzzles. The only downside seems to be that Hashi are quite a bit easier than Sudokus, as far as my (limited) experience of it goes. This is quite a rare sort of puzzle, but I agree that it is more fun than Sudoku. The only reason I don't give it 5 stars is that these days its possible to buy a program to play Hashi, which kind of makes the book redundant.

Hashi, also known as Bridges, is an addictive logic puzzle that should appeal to Su Doku fans (I know it appeals to me). Like Su Doku, Hashi has just a few simple logic rules to follow. By sticking with the logic, the puzzler can solve the puzzle. The idea behind the puzzle is simple. There is a group of circles with numbers in them. They represent islands. The trick is to add bridges between the islands so that they are all connected with none being isolated from the others. The number in each island tells you how many bridges connect to that island. No more than two bridges can connect any two islands. Lastly bridges have to run straight up, down or across (no diagonals). Following those simple rules is all you need. This book has 202 of these puzzles. There are also two in the introduction where some tricks for solving are taught. This is a good guide to solving the puzzles. The remaining puzzles are pretty evenly divided into three categories: Delicious, Pernicious, and Malicious. If you are looking for a new challenge puzzle-wise, this is a good place to look.
