Circuit is an abstract strategy game. It is played on a hexhex board between two players each with their own color of stones. The goal of the game is to make a loop – a connected group of stones of one color, surrounding at least one empty cell or a stone of the opposite color. Each turn, you may place a stone of your color, or pass. A placement is only legal if, after the move, at least one loop could be made (by freely placing stones of either color). You must pass if you have no placement available. For balance, please use the pie rule: One player chooses the first move, then the other player decides whose move that is. —description from the publisher
