REVERSI(6)                       Games Manual                       REVERSI(6)



NAME
       reversi - a game of dramatic reversals

SYNOPSIS
       /usr/games/reversi [ [ -r ] file ]

DESCRIPTION
       Reversi  (also  known as `friends', `Chinese friends' and `Othello') is
       played on an 8×8 board using two-sided tokens.  Each player  takes  his
       turn  by  placing  a token with his side up in an empty square.  During
       the first four turns, players may only place tokens in the four central
       squares of the board.  Subsequently, with each turn, a player must cap‐
       ture one or more of his opponent's tokens.  He does this by placing one
       of  his  tokens  such that it and another of his tokens embrace a solid
       line of his opponent's horizontally, vertically  or  diagonally.   Cap‐
       tured tokens are flipped over and thus can be re-captured.  If a player
       cannot outflank his opponent he forfeits his turn.  The play  continues
       until the board is filled or until no more outflanking is possible.

       In this game, your tokens are asterisks and the machine's are at-signs.
       You move by typing in the row and column at which  you  want  to  place
       your token as two digits (1-8), optionally separated by blanks or tabs.
       You can also type

       c      to continue the game after hitting break (this is only necessary
              if you interrupt the machine while it is deliberating).

       g n    to start reversi playing against itself for the next n moves (or
              until the break key is hit).

       n      to stop printing the board after each move.

       o      to start it up again.

       p      to print the board regardless.

       q      to quit (without dishonor).

       s      to print the score.

       Reversi also recognizes several commands which are valid  only  at  the
       start of the game, before any moves have been made.  They are

       f      to let the machine go first.

       h n    to  ask  for  a handicap of from one to four corner squares.  If
              you're good, you can give the machine a  handicap  by  typing  a
              negative number.

       l n    to  set the amount of lookahead used by the machine in searching
              for moves.  Zero  means  none  at  all.  Four  is  the  default.
              Greater  than  six means you may fall asleep waiting for the ma‐
              chine to move.

       t n    to tell reversi that you will only need n  seconds  to  consider
              each  move. If you fail to respond in the alloted time, you for‐
              feit your turn.

       If reversi is given a file name as an argument, it will checkpoint  the
       game, move by move, by dumping the board onto file.  The -r option will
       cause reversi to restart the game from file and continue logging.
