Connection Games [PDF ebook] 
Variations on a Theme

A comprehensive study of the connection game genre, Connection Games provides a survey of known connection games while exploring common themes and strategies. This book aims to impose some structure on this increasingly large family of games, and to define exactly what constitutes a connection game. Key games are examined in detail and complete rules for over 200 connection games and variants are provided. A connection game is a board game in which players vie to develop or complete a specific type of connection with their pieces. This might involve forming a path between two or more goals, completing a closed loop, or gathering all pieces together into a single connected group.
