Bidirectional board game and method for playing the same

Abstract

A bidirectional board game includes a playing board, and a plurality of playing pieces. The playing board has a matrix of squares defined by horizontal lines and vertical lines configured on a surface of the playing board. The squares are allocated in two regions identified for the two players, respectively. Each square allocated to both of the players includes a diagonal line. The playing pieces are divided into two distinguishable families each controlled by one of the two players. Each family includes a sovereign piece and a plurality of numeral pieces indicating a numeral 1 to 5 . When playing the board game, the two players alternate moving the playing piece. The numeral indicated on the numeral piece is the maximum number of steps allowed to move in one action. Which hostile playing pieces can be captured by the numeral piece is determined by the numeral indicated thereon.

   two families of distinguishable playing pieces controlled by the first player and the second player, respectively, each family having:
 one sovereign piece indicating a sovereign of the family represented with a word or a symbol, two numeral pieces each indicating a numeral  1  represented with a word or a symbol, three numeral pieces each indicating a numeral  2  represented with a word or a symbol, two numeral pieces each indicating a numeral  3  represented with a word or a symbol, two numeral pieces each indicating a numeral  4  represented with a word or a symbol, and two numeral pieces each indicating a numeral  5  represented with a word or a symbol; 
   wherein the playing pieces are placed at one of intersections of the lines and the squares; when the playing pieces are placed at the intersections of lines, the playing pieces are moved along the lines and from the intersections to the intersections; when the playing pieces are placed in the squares, the playing pieces are moved from the squares to the squares.   
   
   
       2 . A method for playing a bidirectional board game, comprising:
 providing a playing board, configured with a matrix of a plurality of squares defined by seven vertical lines indicated by upper-case letters A through G respectively, and ten horizontal lines indicated by lower-case letters a through j respectively on a surface of the playing board, the vertical lines crossing over with the horizontal lines; wherein
 a region defined from the horizontal line a to the horizontal line e is allocated to a first player, a region defined from the horizontal line f to the horizontal line j is allocated to a second player, and a region defined from the horizontal line e to the horizontal line f is a public region; each square of the regions allocated to the players has a diagonal line; 
 the squares are classified into six vertically aligned files; a first file of the squares comprises the diagonal lines (Aa-Bb), (Ab-Bc), (Ac-Bd), (Ad-Be), (Ag-Bf), (Ah-Bg), (Ai-Bh), and (Aj-Bi), a second file of the squares comprises the diagonal lines being minored to the diagonal lines in the first file, a third file of the squares comprises the diagonal lines being mirrored to the diagonal lines in the second file, a fourth file of the squares comprises the diagonal lines being mirrored to the diagonal lines in the third file, a fifth file of the squares comprises the diagonal lines being mirrored to the diagonal lines in the fourth file; and a sixth file of the squares comprises the diagonal lines being mirrored to the diagonal lines in the fifth file; 
   providing two families of distinguishable playing pieces controlled by the first player and the second player, respectively; each family comprising one sovereign piece indicating a sovereign of the family represented with a word or a symbol, two numeral pieces each indicating a numeral  1  represented with a word or a symbol, three numeral pieces each indicating a numeral  2  represented with a word or a symbol, two numeral pieces each indicating a numeral  3  represented with a word or a symbol, two numeral pieces each indicating a numeral  4  represented with a word or a symbol; and two numeral pieces each indicating a numeral  5  represented with a word or a symbol;   setting up the sovereign pieces of the two players on the intersections Da and Dj, respectively, setting up the numeral pieces indicating numeral  1  of the two players on the intersections Ad, Gd, and Ag, Gg, respectively, setting up the numeral pieces indicating numeral  2  of the two players on the intersections Bc, Dc, Fc, and Bh, Dh, Fh, respectively, setting up the numeral pieces indicating numeral  3  of the two players on the intersections Ca, Ea, and Cj, Ej, respectively, setting up the numeral pieces indicating numeral  4  of the two players on the intersections Ba, Fa, and Bj, Fj, respectively, and setting up the numeral pieces indicating numeral  5  of the two players on the intersections Aa, Ga, and Aj, Gj, respectively; and   allowing the first player and the second player to alternately make an action until one of the sovereign pieces is captured;   wherein
 the playing pieces are moved from intersections of the lines to the intersections of the lines; 
 the sovereign pieces are allowed to move one step in one of horizontal and vertical directions, but are not allowed to move diagonally unless the move is along the diagonal line and for capturing the hostile playing piece; 
 each of the numeral pieces is allowed to move no more than a predetermined number of steps in each action, and the predetermined number is equal to the numeral indicated thereon; 
 each of the numeral pieces is allowed to move in one of the horizontal or vertical directions, but is not allowed to move diagonally unless the move is along the diagonal line and for capturing the hostile playing piece; 
 each of the numeral pieces is not allowed to make a turn in one action; 
 when diagonally capturing the hostile playing piece, the numeral piece is only allowed to move one step; 
 the playing piece is not allowed to move in one of vertical and horizontal directions first and then make a diagonal capturing in one action, 
 when moving in one of the horizontal and vertical directions to capture the hostile numeral piece, the numeral piece is allowed to capture the hostile numeral piece with an equivalent numeral or a smaller numeral only; 
 when moving along the diagonal line to capture the hostile numeral pieces, the numeral pieces is allowed to capture the hostile numeral piece having an equivalent numeral or a larger numeral only; 
 the playing piece is allowed to capture the hostile sovereign piece, and the sovereign piece is allowed to capture the hostile playing piece; 
 when a move of the playing piece of the player captures the hostile playing piece, the move stops at where the hostile playing piece is captured, and it is changed to the other player to make a move; 
 the first player who captures the hostile sovereign piece wins. 
   
   
   
       3 . A method for playing a bidirectional board game, comprising:
 providing a playing board, comprising twenty four squares arranged in a matrix defined by seven vertical lines and five horizontal lines;   providing two families of distinguishable playing pieces controlled by a first player and a second player, respectively; each family comprising one sovereign piece indicating a sovereign of the family represented with a word or a symbol, two numeral pieces each indicating a numeral  1  represented with a word or a symbol, three numeral pieces each indicating a numeral  2  represented with a word or a symbol, two numeral pieces each indicating a numeral  3  represented with a word or a symbol, two numeral pieces each indicating a numeral  4  represented with a word or a symbol, and two numeral pieces each indicating a numeral  5  represented with a word or a symbol;   reversing all of the playing pieces to show backsides of the playing pieces to the players so that the players cannot identify the playing pieces;   shuffling the reversed playing pieces and then randomly placing the reversed playing pieces in the squares of the playing board; and   allowing the first player and the second player to alternately make an action until all the playing pieces of one of the families are captured;   wherein
 in each action, the player is allowed to do one of disclosing one of the reversed playing pieces to both of the players and moving one of the disclosed playing pieces one step; 
 the player who makes the first action controls the family of the first disclosed playing piece, and the other player controls the hostile family; 
 after all of the reversed playing pieces have been disclosed, the player is required to move one of the playing pieces of his controlled family in one action; 
 a numeral piece is allowed to capture a hostile numeral piece indicated with an equivalent numeral or a smaller numeral; 
 a sovereign piece is allowed to capture all of the hostile playing pieces except those indicated with numeral  1 ; 
 the numeral pieces indicated with numeral  1  is allowed to capture the hostile sovereign piece; and 
 the first player who captures all of the hostile playing pieces wins.
