## DESCRIPTION

           Panex - A grooved sliding tile puzzle created  by  Toshio  Akanuma  and
           manufactured  by  the Tricks Co., Ltd of Tokyo, Japan (a Magic Company)
           in the 1980's.  Mathematicians at Bell Laboratories calculated the num-
           ber  of  moves  to  be 27,564 to 31,537.  It came in two varieties: one
           with a magenta and a orange pyramid of order 10 on silver tiles; in the
           gold  version pieces of each color look alike (i.e. no pyramid is drawn
           on them), this is a little harder.  The goal in this puzzle is to  sim-
           ply  exchange  the  2 piles.  Pieces with smaller trapazoids can not go
           down as far as pieces with bigger trapazoids.

           The original Tower of Hanoi puzzle is the invention  of  Edouard  Lucas
           and was sold as a toy in France in 1883.  The legend of 64 disks in the
           great temple of Benares of the god Brahma is also his  invention.   The
           goal in this puzzle is to move the pile from the left side to the right
           most column.  Unlike panex, a large trapazoid can not go on  top  of  a
           smaller one, but pieces always fall to the bottom.

           The  original  Algorithme  6  is 2 stacks of 3 wooden spheres on 2 of 3
           posts.  The spheres come in 3 different sizes.  The  goal  goal  is  to
           swap  the  spheres using the posts without putting a bigger sphere on a
           smaller one and without exceeding the size of the post.  It was created
           and  produced  by  Patrick Farvacque around 1997.  The puzzle presented
           here has a simpler solution because the tiles are all the  same  height
           (i.e. a 39 move solution as opposed to 66).

## FEATURES

           Press  "mouse-left"  button to move a tile in the top tile of a column.
           Release "mouse-left" button on another column to move the tile to  that
           column.  It will not move if blocked.

           Click "mouse-right" button, or press "C" or "c" keys, to clear the puz-
           zle.

           Press "R" or "r" keys to read a saved puzzle.

           Press "W" or "w" keys to save (write) a puzzle.

           Press "U" or "u" keys to undo a move.

           Press "E" or "e" keys to redo a move.

           Press "S" or "s" keys to auto-solve.  Unfortunately,  its  only  imple-
           mented from the starting position.

           Press  "M"  or  "m"  keys to switch between Hanoi (one pyramid column),
           Algorithme, and Panex, (each has two pyramid columns) modes (they  each
           have different rules).
           In  Hanoi,  one  can not place larger trapezoid on a smaller trapezoid.
           Here the goal is to move the pile from the left peg  to  the  rightmost
           peg.
           Algorithme  is  similar, here we must exchange tiles and we are limited
           by the size of the  stack.   A  move  from  stack  1  to  stack  3  and
           vice-versa when stack 2 is full.
           In  Panex,  a  tile  can  not go lower that its initial starting point.
           Here again, the goal is to exchange the 2 piles.

           Press "I" or "i" keys to increase the number of tiles.

           Press "D" or "d" keys to decrease the number of tiles.

           Press ">" or "." keys to speed up the movement of tiles.

           Press "<" or "," keys to slow down the movement of tiles.

           Press "@" key to toggle the sound.

           Press "Esc" key to hide program.

           Press "Q", "q", or "CTRL-C" keys to kill program.

           Unlike other puzzles in the collection there is no way to  move  pieces
           without drag and drop.

           The title is in the following format (non-motif version):
                  x{hanoi  |  algorithme  | panex}: <Number of rows> @ (<Number of
                  moves>/{<Record number of moves> <user name>|"NEVER  noaccess"})
                  - <Comment>
           If  there  is no record of the current puzzle, it displays "NEVER noac-
           cess".

## RECORDS

           You  must clear the puzzle before a record is set, otherwise an assump-
           tion of cheating is made if it is solved after a get or an auto-solve.

## SAVE FORMAT

           Here is the format for the xpanex configuration, starting position, and
           the movement of its pieces.

                  mode: 0-2 <0 hanoi, 1 algorithme, 2 panex>
                  tiles: 1-10 <number of tiles in a column>
                  moves: 0-MAXINT <total number of moves>

                  startingPosition:  <array  pairs  of column and position of each
                  tile>

           This is then followed by the moves, starting from 1.
                  move #: <from_column> <to_column>
           from_column is the top tile of the column
           to_column is where that tile is moved to.
