Help For Koan
Introduction
Welcome to the network Koan server. The rules of Koan are below. The commands are the same for all pbmserv games.
Object of Game:
Each player has six octagonal and five square playing
pieces set out on the board at the start of play as
shown in diagram 1.
1. One player uses the white playing pieces and the other
uses black. White goes first.
2. On each turn a player moves one pieces one space forwards.
No pieces can move backwards or sideways. Pieces cannot
move directly from a square space to another square space.
Square pieces are permitted to land on both square and
octagonal spaces: similarly octagonal pieces can land on
both types of spaces; see diagram 2.
3. No two pieces may be on the same space at the same time
n.b. see the rules for capturing.
Capturing pieces.
4. When a permitted move lands a piece on a space occupied by
an opposing piece, that piece may be taken on condition that;
a. octagonal pieces can only take opposing pieces (either type)
which are standing on octagons (green spaces) and,
b. square pieces can only take opposing pieces (either type)
which are standing on squares (square spaces). see diagram 3.
5. Only one piece may be taken on any one turn and the capturing
piece occupies the space of the opponents lost piece. This
capture completes the player's turn to move.
6. Players do not have to take opposing pieces when the
opporturnity aries. They choose if and when to do so.
