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.

A smart and funny YA novel from Jennifer Honeybourn, When Life Gives You Demons Some people have school spirit. Shelby Black has real ones. Shelby Black has spent the past six months training to be an exorcist. Her great-uncle Roy—a Catholic priest—has put her through exorcist boot camp hell, hoping to develop her talent, but ohmygod, he still doesn’t trust her to do an exorcism on her own. High school is hard enough without having to explain that you fight demons for a living, so Shelby keeps her extracurricular activity to herself. The last thing she wants is for her crush, Spencer, to find out what she does in her off time. But Shelby knows how to keep a secret—even a big one. Like the fact that her mom left under mysterious circumstances and it’s all her fault. Shelby is hellbent on finding her mom, no matter what it costs her—even if what it ends up costing her is her soul AND a relationship with Spencer.

The "Hidden Logic of Sudoku" provides the first systematic perspective of the logical symmetries of the popular game. These are fully exploited to define new graphical representations, new kinds of resolution rules and a precedence ordering of the rules consistent with their logical complexity. The set of rules defined in the book is illustrated with a hundred of puzzles together with their full resolution paths. It suffices to solve almost any puzzle without making guesses or assuming the uniqueness of a solution. It has been fed into an Artificial Intelligence (AI) engine and a large database of puzzles has been processed, leading to a precise evaluation of the efficiency of each rule. The book is intended for both advanced Sudoku players (who will discover many new facets of the game and a new, systematic approach to the resolution rules) and for teachers or students of Logic or AI (who will appreciate the strict logical foundations).
