This is the third part in our series on classic board games that made the transition or were ported to early home computers.
Othello, sometimes referred to as Reversi is a strategy board game that takes minutes to learn how to play but much longer to master. This is one of those games that I wish I could play, every now and then I pull it out and try again but I'm a terminally bad Othello player. The object of the game is very simple, to have the majority of your coloured disks on the board at the end of the game.
Original Program Instructions
The game always begins with the Black and White player each placing two disks in the center of the board as shown in Figure 1.
The object of the game is to capture more squares on the board than your opponent. To capture a square(s) you must outflank your opponent's disk(s). To outflank means to place a disk on the board so that your opponents row (or rows) of disks is bordered on each side by a disk of your colour. A row maybe made up of one or more disks,

Game Board - Initial Setup
Below is an example of how outflanking works. Figure 1 shows the White player with two White disks on either side of a Black disk. Figure 2 shows that the Black disk has been "flipped" and is now a White disk. You score one point for each disk you flip and your opponent looses one point for each disk they loose.
You can outflank your opponent in diagonal, horizontal or vertical directions. You're also able to outflank in more than one direction at a time. So that's the basic game play, pretty simple and straight forward but mastering the game will take more time.
If you have no moves you can make to outflank your opponent, you will loose your turn and the cursor will change to your opponent's colour. If neither player can make a move then the game ends.
To my great shame I can't be of much help with strategy for this game as I'm probably even a much worse Othello player than I am a Chess player. I know that the corner squares are very important to control as they can't be outflanked. The squares on the outside edge of the board are also important as they can only be outflanked in one direction. Other than that you're on your own.
