ルール書き(英語)

ということで、英語のルール。


Overview

YWF (Yoi-ko, Warui-ko, Futsu-no-ko) is a strategy board game for two players. One plays as Yoi-ko, which means Good boy, and another plays as Warui-ko, which means Bad boy, and they try to become the majority on the board. In addition to Yoi-ko and Warui-ko, however, there are unstable Futsu-no-ko, which means Common boy, too...

Board, Piece, and Token

YWF uses a board with 9x9 grid. (Figure 1)

A piece is placed in a square of the board. (Figure 2)

(Figure2. How to place a piece on the board)

One side of a piece is colored with white and another side is colored with black, and they represent Yoi-ko and Warui-ko respectively. (Figure 3, 4)

A standing piece represents Futsu-no-ko. (Figure 5)

Besides the pieces, there is a token. The token is placed in the outside column of the board and indicates the rights of Change (mentioned later). (Figure 6)

Game Play

In the game, each player does one Action in turn, from Warui-ko player.

Each player do either Play or Change as Action. If a player cannot do either, the player must do Pass.

By Play or Change, the Futsu-no-ko or opponent pieces lying between the player's pieces are changed to the player-side pieces: Futsu-no-ko pieces become player's pieces and opponent pieces become Futsu-no-ko pieces. Players try to make their own pieces more on the board like this.

Details of Action

Play

In the action Play, the player places one player's piece on an empty square of the board. The player must change one or more pieces which have already been on the board by Play.

By placing a piece, the pieces lying between the placed piece and the player's piece are changed in the 8 directions of each horizontal, vertical, and diagonal. (Figure 8, 9)

  • If the lying piece is a Futsu-no-ko, it becomes a player's one.
  • If the lying piece is an opponent one, it becomes a Futsu-no-ko.

If one or more empty squares are between the placed piece and the player's piece, any pieces are not changed in the direction.

Change

In the action Change, the player changes one Futsu-no-ko on the board to the player's piece. The player must change one or more pieces which have already been on the board by Change, in addition to the changed piece. Also, the player cannot do Change if the opponent player did Change just before or the token is positioned in the opponent side.

By changing a Futsu-no-ko on the board, the pieces lying between the changed piece and the player's piece are changed in the 8 directions of each horizontal, vertical, and diagonal. (Figure 8, 9)

  • If the lying piece is a Futsu-no-ko, it becomes a player's one.
  • If the lying piece is an opponent one, it becomes a Futsu-no-ko.

If one or more empty squares are between the changed piece and the player's piece, any pieces are not changed in the direction.

After doing Change, the token moves.

  • If the token is positioned in the player's side, it returns to the center.
  • If the token is positioned in the center, it goes to the opponent side.
Pass

If the player cannot do either Play or Change, the player must do Pass. By doing Pass, the turn is merely passed to the opponent.

A player can do Pass only if the player cannot do either Play or Change. If the player can do either Play or Change, the player must do either.

Game End

The game ends if no square is empty, both players must do Pass, or no piece of one player is on the board.

The player with more pieces on the board at the end of the game wins. If players have the same number of pieces on the board, the player with the token wins. If the game is still tied, the game ends in a draw.


なお、英語だと表現しづらい日本語もあるので、そういう場合、日本語の表現を英語の表現に合わせてあげるといい。
その方がより厳密な表現になることが多いし、日本語ルールと英語ルールの相互チェックにもなるので。
