Help For Su-do-ku

Introduction

   Welcome to the network Su-do-ku server. The rules of Su-do-ku are
   below. The commands are the same for all pbmserv games.

Rules of Su-do-ku

This is not your Newspaper's Su-do-ku

   Standard Su-do-ku is a single player puzzle. The normal grid is a 9x9
   array of cells subdivided into 9 3x3 supercells.
          - 6 -|1 - 4|- 5 -
          - - 8|3 - 5|6 - -
          2 - -|- - -|- - 1
          -----+-----+-----
          8 - -|4 - 7|- - 6
          - - 6|- - -|3 - -
          7 - -|9 - 1|- - 4
          -----+-----+-----
          5 - -|- - -|- - 2
          - - 7|2 - 6|9 - -
          - 4 -|5 - 8|- 7 -

         Figure 1 -- Typical Su-do-ku Puzzle

   The object of a su-do-ku puzzle is to place the numbers 1-9 on the
   grid in such a way as each column, row and supercell contains all of
   the numbers 1-9 with no repeats.

Object of the Game is Different

   On a su-do-ku grid, players take turns adding digits to the board in
   an attempt to be the last player to be able to make a valid move. If a
   cell becomes "dead" (due to the fact that all of the possible digits
   are already in use in that row+column+supercell) no piece can be
   played there.

Challenge Options

   sudoku challenge [-size=XxY] [-showdeadcells|-hidedeadcells] userid1
   userid2 [ ... userid6]

   starts a new game between up 2 six players (userid1, userid2, ...
   userid6).

   The -size parameter sets the dimensions of a supercell. the default is
   3x3. valid values range from 2x2 to 6x6 to 7x5

   if the total number of cells in a supercell is less than 10 (2x2, 2x3,
   2x4, 3x3) the digits in the cell will be 1..n (where n is the number
   of cells in the supercell)

   if the total number of cells in a supercell is 10 or more (2x5, 2x6,
   3x4, 3x5, etc.) the digits in the cell will be 0..9 and the letters
   A..n-1 (where n is the number of cells in the supercell and A=10,
   B=11, C=12, etc.)
          A B C D E F
       1  - 6 -|1 - 4  1
       2  - - 2|3 - 5  2
          -----+-----
       3  2 - -|- - 1  3
       4  3 - -|4 - 6  4
          -----+-----
       5  - - 6|- - -  5
       6  1 - -|6 - 3  6
          A B C D E F

         Figure 2 -- Typical '-size=3x2' Su-do-ku grid

   The -showdeadcells parameter (default) causes dead cells to no longer
   be displayed with the '-'. They cease to be.

   The -hidedeadcells parameter causes dead cells to be displayed
   normally (with the '-').

Movement Rules

   A su-do-ku move consists of 2 parts. The row/column of the position
   where the digit is to be placed, and the digit to place there. e.g.
   "B3-5" would put a 5 in column B, row 3.
