    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.
