Help For Zrtz+11

Introduction to playing Zrtz+11 on Richards PBeM-server.

Zrtz+11 has the same rules as plain Zrtz, but the board consists of 11 extra rings. If you're not a good Zrtz-player, you probably shouldn't be playing this variant.

This is not an introduction to Zrtz+11. If you don't know the game yet but want to learn then you can go and buy it or check the gipf-website ( for the rules. In any case, you should check the gipf-website to know how the moves of a game are written down.


The challenge-command for Zrtz+11 is the same as for most games, just give the userid of both players and the fun can start.

zertz+11 challenge useridplayer1 useridplayer2


  • If you use the previous command you will play Zrtz+11 according to the tournament rules. If you want to play with the standard rules then you have to use the '-standard' option.

    zertz+11 challenge -standard useridplayer1 useridplayer2

  • If a player has only one possible capture-move, then the server will automatically make this move without user-intervention. If you you want to make these moves yourself then you have to use the '-noforcedmoves' option when starting the game.

    zertz+11 challenge -noforcedmoves useridplayer1 useridplayer2


    The move-command for Zrtz+11 is a little more complicated than most games.
    The basic command is of the form:
    zertz+11 move gamenr userid password zertzmove

    When playing a game of Zrtz+11, there are 2 possible actions. Depending on the situation on the board, the implementation will indicate what must be done to go on with the game.

    1. Normal move, bring a new marble into play and remove a tile

      The first character of your move indicates the color of the marble (W for white, G for gray, B for black) you want to add to the board, followed by the position where you want to place it. Then a ',' and the position of the tile you want to remove.

      There are situations where you can't remove a free tile because there are none. In that case you should use 'xx' for the position of the tile to be removed.

    2. Capture one or more marbles

      The first position indicates the marble that will jump over other marbles to capture them. After this come separated by '-' the positions it is jumping to.


    If you made a wrong move, you can correct this with the UNDO-command. But your opponent will have to agree with you.
    zertz+11 move gamenr userid password undo
    your opponent will then get the question if he wants to accept the undo-command.
    if he agrees he should reply with:
    zertz+11 move gamenr userid password accept
    if he doesn't want the undo to take place:
    zertz+11 move gamenr userid password reject

    How to interpret the ASCII-representation of a Zrtz+11-game

    • Every hexagon represents one of the tiles that constitute a Zrtz+11-board. If a tile is removed from the board then the hexagon is replaced by a dot.

    • White, gray and black marbles are shown on the board as the letters W, G and B in the middle of a hexagon.

    • The following drawing shows a typical game-situation:
                         A5 B6 C7 D8 E7 F6 G5 H4
                                  .  __
                               .  __/  \      
                            .  __/G \__/.     
                         .  __/  \__/  \   .  __
                           /  \__/  \__/.  __/  \
                         . \__/  \__/  \__/  \__/
                            . \__/  \__/  \__/.
                         .  __/  \__/B \__/  \
                         __/  \__/  \__/  \__/.
                        /W \__/B \__/  \__/  \
                        \__/  \__/  \__/  \__/.
                        /B \__/  \__/. \__/  \
                        \__/  \__/  \   . \__/
                           \__/  \__/.        
                              \__/  \

    • Coordinates on a Zrtz+11-board consist of a letter (A-H) and a number (1-8).

      The letter indicates the column, the number is the position within the column when you start counting from the bottom. The following drawing should make things clear:

                         A5 B6 C7 D8 E7 F6 G5 H4
                         A1 B1 C1 D1 E1 F1 G1 H1
