This is a computer version of the board game, also known as
Othello, and can be played by two people against each other or
by one player against the computer. Reversi is a sort of thinking
man's draughts, originally plaed with counters on an eight by eight
board.
Full instructions for playing the computer version, including
rules and playing hints, are supplied. The tape loaded first
time, trying RUN produced a menu of options. The full range of options
is superb; one or two players, sample game, change sides, choice
of who starts, replay game, set up board and nine levels of play.
The program is written in machine code and has a fast response. At
level one it's almost instantaneous, although at higher levels it
slows down considerably. The screen display is set out simply and
clearly with an update score displayed. Moves are entered by letter-number,
D6 for example, and invalid moves are not allowed. The program seems to
be well error-trapped - it resisted my best efforts to confuse it.
It has just about all the features that both beginners and experts are
likely to need and its playability ability is high indeed. I refuse
to say how many times it beat me at level one.
