JETAN, OR MARTIAN CHESS
For those who care for such things, and would like to try the
game, I give the rules of Jetan as they were given me by John
Carter. By writing the names and moves of the various pieces on
bits of paper and pasting them on ordinary checkermen the game
may be played quite as well as with the ornate pieces used upon
THE BOARD: Square board consisting of one hundred alternate black
and orange squares.
THE PIECES: In order, as they stand upon the board in the first
row, from left to right of each player.
Warrior: 2 feathers; 2 spaces straight in any direction or
Padwar: 2 feathers; 2 spaces diagonal in any direction or
Dwar: 3 feathers; 3 spaces straight in any direction or
Flier: 3 bladed propellor; 3 spaces diagonal in any direction or
combination; and may jump intervening pieces.
Chief: Diadem with ten jewels; 3 spaces in any direction;
straight or diagonal or combination.
Princess: Diadem with one jewel; same as Chief, except may jump
Flier: See above.
Dwar: See above.
Padwar: See above.
Warrior: See above.
And in the second row from left to right:
Thoat: Mounted warrior 2 feathers; 2 spaces, one straight and one
diagonal in any direction.
Panthans: (8 of them): 1 feather; 1 space, forward, side, or
diagonal, but not backward.
Thoat: See above.
The game is played with twenty black pieces by one player and
twenty orange by his opponent, and is presumed to have originally
represented a battle between the Black race of the south and the
Yellow race of the north. On Mars the board is usually arranged
so that the Black pieces are played from the south and the Orange
from the north.
The game is won when any piece is placed on same square with
opponent's Princess, or a Chief takes a Chief.
The game is drawn when either Chief is taken by a piece other
than the opposing Chief, or when both sides are reduced to three
pieces, or less, of equal value and the game is not won in the
ensuing ten moves, five apiece.
The Princess may not move onto a threatened square, nor may she
take an opposing piece. She is entitled to one ten-space move at
any time during the game. This move is called the escape.
Two pieces may not occupy the same square except in the final
move of a game where the Princess is taken.
When a player, moving properly and in order, places one of his
pieces upon a square occupied by an opponent piece, the opponent
piece is considered to have been killed and is removed from the
The moves explained. Straight moves mean due north, south, east,
or west; diagonal moves mean northeast, southeast, southwest, or
northwest. A Dwar might move straight north three spaces, or
north one space and east two spaces, or any similar combination
of straight moves, so long as he did not cross the same square
twice in a single move. This example explains combination moves.
The first move may be decided in any way that is agreeable to
both players; after the first game the winner of the preceding
game moves first if he chooses, or may instruct his opponent to
make the first move.
Gambling: The Martians gamble at Jetan in several ways. Of course
the outcome of the game indicates to whom the main stake belongs;
but they also put a price upon the head of each piece, according
to its value, and for each piece that a player loses he pays its
value to his opponent.
