Qua (board game)

Qua is a three-dimensional (3D) abstract strategy game for three players. It is an extension of the two-dimensional, two player game called Gale, marketed as Bridg-It[1]. Qua is played on a 3D game board grid composed of N3 cells in the shape of a cube, where N is typically odd and equal to the number of cells along each edge of the game board. It is the first connection game that is fully 3D (no fully 3D connection games are listed in Cameron Browne's definitive book on the subject)[2].

The objective of Qua is to be the first player to complete a connected path of cells containing their game play pieces between their two opposite faces of the game board cube.

The 3D game board does not start out empty. Some of the cells in the game board are initially filled-in with one of three game play pieces, called qua. The three qua game play pieces--one for each player--are distinguished from each other by shape and color.

Rules

• Players choose their qua at the beginning of the game and decide who will go first, second and third in sequential turn order.
• Each turn, players place one of their qua in an empty cell in the game board cube.
• Players may only place qua in an empty cell if it is adjacent to two cells containing that player's qua, or one such cell and one of the player's game board faces.
• If a player cannot make a move, they skip their turn.
• The game ends when the first player connects their two faces of the game board.

Variants

• Dice Qua is a variant that allows two players to play Qua. On each player's turn they roll a die to determine which qua they will play. This can end in a draw if the third, unselected qua blocks both of the game's players from winning.
• Cooperative Qua[3] is a variant that allows all three players to win. The objective is to help your opponents instead of blocking them. The game continues even after the first player connects their two faces.
• Qua Misère[3] is a variant that reverses the objective. The first player to connect their two faces loses. In this variant there are two winners.
