King's Valley Labyrinth is a new extension game of original King's Valley. Board size is enlarged to 7x7 square grid and 4 pillar stone spaces are added. As in the original game the simplicity of the game stems from the fact that the movement of all the pieces is the same. All pieces move horizontally or vertically or diagonally. But when a piece is moved it must continue its movement until, and only until, it reaches a vacant square adjacent to (alongside) either the edge of the board or another piece or pillar stone. The game is decided when one player moves the King piece to the center square--the King's Valley--thus winning the game.
