This challenging visual puzzle will appeal to lovers of logic and deduction brain teasers. How To Play: A map grid shows two towns, typically A and B. The objective of the puzzle is to lay down tracks to connect the two towns. Numbers around the outside of the grid tell you how many pieces of track are to be placed in each row and column. You can only use straight (horizontal and vertical) and curved (right and left) rails and the track cannot cross over itself. There is something very satisfying in the laying down of tracks. The puzzles are arranged with varying levels of difficulty, where difficulty is largely dependent on the size of the map grid (from 6x6 to 10x10). Puzzles included cover three levels of difficulty: 70 Easy, 70 Moderate, and 60 Difficult.

Hashi (short for Hashiwokakero, meaning "build bridges") is a new logic puzzle from Japan. In Hashi, the goal is to join islands together with up to two vertical or horizontal bridges, so that every island is connected. The larger in number value the island, the more bridges connect to it (an island of size 6 must be connected to 6 bridges), and no bridge can cross another. Successful logic puzzles have certain things in common: a unique game with one solution, easy to pick up, fun and challenging, able to be put down and picked back up again. Hashi has all these qualities, and puzzle master Alastair Chisholm has created 201 puzzles in three levels of difficulty--Easy, Medium, and Hard; you'll be thinking about them even when you're not working on them.
