Survey of the game>

This game is known as "Othello" or "Reversi". The object of the game is to have the majority of your color discs on the board at the end of the match.

At the opening of the match, each player chooses one color to use throughout the match, and places two discs each as Fig.1.

Every move must consists of "sandwiching" the opponent's disc(s), then flipping the sandwiched disc(s) to your color. To sandwich means to place a disc on the board so that the opponent's row(s) of disc(s) lie between your color discs at each end.
For example, the placement of black disc at X sandwiches the row of three white discs.(See Fig.2) Then sandwiched discs are flipped to black.(See Fig.3)

Rules of the game

1. Black moves the first.

2. A disc may sandwiches any number of rows of disc(s) in any number of directions at the same time. Horizontally, vertically or diagonally. (See Fig.4 and Fig.5)
Fig.4 Fig.5

3. All discs sandwiched must be flipped, even if it is the player's advantage not to flip them at all.

4. You may not skip over your own color disc to sandwich the opponent's disc. (See Fig.6 and Fig.7)

5. Disc(s) may only be sandwiched as a direct result of a move and must fall in the direct line of the disc placed down. (See Fig.8 and Fig.9)

6. In your turn, if you can't sandwich any opponent's disc, your turn will be invalidated and the opponent moves again. However, if a move is available to you, you may not pass your turn.

7. Once a disc is placed on the board, it can never be moved to another place later.

8. When it is no longer possible for either player to move, the match is over. It is possible of a match to be over before all 64 squares are filled. The player with the majority of his or her color discs on the board is the winner.
