Quax

 Overview Quax is a two-player abstract board game played on a square board that was invented by Bill Taylor in 2000. This game is a member of the connection game family including such game as Hex, Y, Atoll and Crossway.

 Board Quax is played on a square board. The author suggests 11x11 (as usual, smaller is more tactical, larger more strategic). It's possible to use a board with Archimedean tiling: the small rhombic cells are used to connect diagonally adjacent octagonal cells. The left and right edges are colored white while the top and bottom edges are colored black:

Object of the Game

The goal of Quax is to form a connected chain of your stones linking the opposite edges of the board marked by your color. I.e. White should connect the Left and Right edges and Black should connect the Top and Bottom edges. A corner is considered to be part of both adjoining edges.

Two stones are considered to be connected to each other if they are horizontally or vertically adjacent or if they are diagonally adjacent and there is a rhombic tile of the same color between them.

Below are two examples of the described variants of a chain:

No draws are possible in Quax.

 Play The game begins with an empty board. Each player has an allocated color: Black or White. Starting with Black, players take turns doing one of the following actions: placing a stone of their color in any empty cell of the board; placing a rhombic tile of their color in an empty rhombic cell between two diagonally adjacent player's stones. Since the first player has a distinct advantage, the pie rule is used for making the game fair. This rule allows the second player to switch colors after the first player makes his first move.
