Initial setup

The board has 13 x 13 squares.

Pieces

King

Moves as in usual Chess, except there is no castling.

Snake

Moves one square vertically and then, slides away of an indefinite number of squares diagonally. It can not jump and the unobstructed path must start with the vertical movement.

Ship

Moves one square diagonally and then, goes away of an indefinite number of cases vertically, never horizontally.

Mammoth

Steps horizontally, vertically or diagonally one or two squares, leaping over the intermediate square if it is occupied

Squirrel

Jumps at 2 squares

Cheetah

Jumps at 3 squares

Troll

Makes a 3-step orthogonal or diagonal jump, no matter what any intermediate square contains. In addition, it moves 1 step forward and captures 1 step diagonally forward (like a Pawn). This permits the Troll to reach any square on the board. It can promote to wolf only when it moves like a Pawn, never by jumping 3 squares

Prince

A non-royal King who moves and captures one square in any direction, but without being hindered by check. Like the Pawn, he can also move without capturing to the second square straight ahead. When he reaches the last row it can promote to wolf.

Pawn

Moves straight forward one or two square from any position on the board, without capturing. It captures one square diagonally forward. As a consequence, the en-passant capture is possible every time an opposite Pawn or Prince has advanced two squares. When he reaches the last row it can promote to Direwolf.

Griffon

This piece may appear in this game by promotion of a Ship. It moves one square diagonally and then, slides away of an indefinite number of squares vertically or horizontally.

Rhinoceros

This piece may appear in this game by promotion of a Snake. It moves one square vertically or horizontally and then, slides away of an indefinite number of squares diagonally.

Hawk

It jumps horizontally, vertically or diagonally two or three squares, leaping over the intermediate squares if they are occupied.

Direwolf

This piece may appear later on by promotion of a Pawn, a Prince or a Troll. It jumps on any square situated at 2 or 3 squares distance from where it stands.
