■ Rule explanation
Each player has 10 walls. Do either "move one piece" or "install one wall" on your turn, advance the turn in order, and first your piece is in the farthest row (any square is fine) ) Is the winner.
The top can be moved by one square back and forth and left and right in a place that is not blocked by the wall. It cannot be moved diagonally. Also, if it is adjacent to the opponent's piece, it can jump over the opponent's piece. However, if there is a wall ahead of you when you try to jump over, you can move to either side of the opponent's piece.
The wall must be installed between the squares so that it spans two squares. It cannot be installed in the same place as other walls, but it can be installed as long as it passes between walls. Also, it cannot be placed so that the opponent cannot reach the goal. It is necessary to place it in at least one place so that the road to the goal remains.
