Reversi is played in a square board (8x8 usually). Each player, in turns, must
put a piece of his/her/it colour in  the board. A piece can  only by placed in
a position if by doing  so pieces of the  opposite  colour can be reversed  to
the player's color.	

When a piece is placed  on the board all   the pieces of  the opposite  colour
that are  in a straight line  between the  new  piece and another  of the same
color are reversed.  The  two  pieces of the   same  color can be  in the same
vertical, horizontal or diagonal line. 

In certain situations, more then  one line can be  formed when inserting a new
piece. In  this case, all pieces that  can  be reversed  in each line  must be
reversed.

If a player cannot reverse any piece then loses his/her/it  turn.  The goal is
to  complete the board  with the maximum   number of pieces  with the player's
color. Wins the player with more pieces of his/her/it color.
