Uisge

Uisge is a game played on a rectangular game board consisting of 42 squares. The game utilizes twelve round stone game pieces, divided equally between white and black, with each piece having one blank side and one side with a crown. At the beginning of the game, all stones are placed on the board with the blank side facing up. Similar to chess,the player controlling the white pieces takes the first turn, followed by the player controlling the black pieces.

On a player's turn, a stone can be moved in one of two ways:

• Jump: A piece may jump over a neighbouring own or an opponent's piece in a horizontal or vertical direction, provided the landing space is empty. The jumping stone is flipped, making a blank stone a crown stone and a crown stone a blank stone.
• Move: Only crown pieces may move. It may be moved to an empty adjacent empty field in a horizontal, vertical or diagonal direction. The crown stone is not turned over.

A stone may only be moved if all stones on the field are still connected to each other in a horizontal or vertical direction. No stone or group of stones may stand alone and stones cannot move into a space that would leave them only diagonally connected to the chain.[2]

The object of the game is to flip all ones stones to the crown side before the opponent.

Uisge was featured as a "break-away game" in the 1983 Spielbox magazine.[3][4] It was awarded the 1984 Spiel de Jahres special award for "Beautiful Game".[1][5]
