You play Reversi on a board similar to that of draughts or chess.
Moves are made by placing a counter on a vacant square next to an
opponent's piece - the idea being to have as many counters as
possible showing your colour when the game ends.
So you must "reverse" your opponent's pieces - your opponent being
the computer.
In this version you move by entering the row number, then the
column - the board is numbered to help you. The computer then
acts on the move, and if you try anything illegal it will tell you to
re-enter the move.
There are two ways to play. In one you can take your time to move. In
the other, you have to make your move in four seconds or lose your go.
Be extremely careful when pressing keys to follow instructions. It's
very easy to clear the program and end up loading it again.
As yet another computer version of a popular board game, this one
should have been a lot better.
