Piece moves

The game is played with pieces of four different colors as shown in the diagram. Each player has four pieces on the back rank with four pawns in front of them on the second rank. The four pieces are king, elephant, horse and boat (or ship in some sources). The king moves like the chess king
King (chess)
In chess, the king is the most important piece. The object of the game is to trap the opponent's king so that its escape is not possible . If a player's king is threatened with capture, it is said to be in check, and the player must remove the threat of capture on the next move. If this cannot be...

. The boat moves two squares diagonally in any direction as shown in the diagram, jumping over the intervening square. Note that this differs from most ancient chess-like games where it is the elephant which normally corresponds to the chess bishop.

The pawn
Pawn (chess)
The pawn is the most numerous and weakest piece in the game of chess, historically representing infantry, or more particularly armed peasants or pikemen. Each player begins the game with eight pawns, one on each square of the rank immediately in front of the other pieces...

 also moves as in chess, but does not have the option of an initial double-square move. Each of the four players' pawns moves and captures in a different direction along the board, as one would expect from the initial player's setup. For example, the red pawns which start on the g-file above move left across the board, promoting on the a-file. Also, the pawn's promotion rules are different; one must promote to the piece that starts on the same file (or rank) of the promotion square (king included) and one can promote only after one's piece of that type has been captured.

Boat triumph

When a boat moves in such a way that a 2x2 square filled with boats is formed, it captures all three boats of other players (see diagram). This rule is called boat triumph.

Dice throws

On each turn two dice are thrown. Usually oblong (four sided) stick dice were used. Players were allowed to throw the dice in the air and catch them, exercising some control over the outcome. However, playing with cubic dice is also possible. Pieces to be moved are determined by dice numbers (note that the stick dice didn't have 1 and 6):
  • 1 or 5 - pawn or king
  • 2 - boat
  • 3 - knight
  • 4 or 6 - elephant

On each turn two moves may be made, one for each die. The same or two different pieces may be moved, and the player may skip one or both of his moves if desired.

Scoring

There is no check or checkmate. The king can be captured like any other piece. The goal of the game is to collect as many points as possible. Points are scored by capturing opponents' pieces, according to this scale:
  • pawn - 1
  • boat - 2
  • knight - 3
  • elephant - 4
  • king - 5.


A score of 54 points is awarded to a player who manages to capture all three opponents' kings while his own king remains on the board. This value is a sum of points of all pieces in three armies.
