<abstract role="description">

<para><application>Iagno</application> is the two player strategy game of Othello, which is also known as Reversi and is similar to Go. The pieces are tiles that are black on one side and white on the other and the objective is for the player to flip his or her opponent's tiles to his or her colour, while keeping the opponent from doing the same. Once the board is filled with tiles, the winner is the player with the most of his or her colour tiles on the board.</para>

<title>Introduction</title>

<title>What is Iagno?</title>
171
<para><application>Iagno</application> is a computer version of the game Reversi, more popularly called Othello. <application>Iagno</application> is a two player strategy game similar to Go. The board is 8-by-8 with tiles that are black on one side and white on the other side. The object of <application>Iagno</application> is to flip as many of your opponent's tiles to your colour as possible without your opponent flipping your tiles. This is done by trapping your opponent's tiles between two tiles of your own colour.</para>
173
<para>To run <application>Iagno</application>, select <guimenuitem>Iagno</guimenuitem> from the <guisubmenu>Games</guisubmenu> submenu of the <guimenu>Main Menu</guimenu>, or type <command>iagno</command> on the command line.</para>
177
<title>Why is Othello called Iagno?</title>
178
<para>You're probably wondering why this game is called <application>Iagno</application> instead of Othello or even gnothello. The answer is complicated, and involves things like trademarks and lawyers and whatnot. Instead of leaving it at that, I'll tell you a long and complicated lie about the origin of the name <application>Iagno</application>.</para>
179
<para>On a stormy night, like those depicted so much in England, a lonely programmer was sitting in front of his computer screen. Ian had finished his masterpiece in gaming. It was a fully interactive game of Othello and he decided to play a pun with the name and called it gnothello for the game was written using GNOME.</para>
180
<para>Later his buddies came over and like all programmers he showed off his masterpiece. They all laughed in his face and told Ian that his game was worthless and a pitiful attempt to be a true hacker. After Ian kicked them out he decided to rename his program Iago <footnote>
181
<para>Iago is Othello's nemesis in the play <citetitle>Othello</citetitle> by William Shakespeare.</para>
182
</footnote> for the evil which had manifested itself due to his game. Yet it still didn't sound right. All GNOME programs have some part of GNOME in it, Ian thought. After much thought he decided on the name we have come to cherish, <application>Iagno</application>.</para>

<title>Playing Iagno</title>

<para>The board starts with four tiles arranged in a box on the middle of the board. The tiles have the same colour at each corner, as shown in <xref linkend="start-shot"/>.</para>

<para>Black goes first and places a tile on the board such that it traps white's tiles between two of black's tiles. When black places a tile on the board all of white's tiles between black's newly placed tile and another black tile, in a horizontal, vertical, or diagonal row, are flipped over and become black, as shown in <xref linkend="first-shot"/>.</para>

220
<para>When there is tile trapped between two tiles, of an identical colour in the same row, the player captures tiles until another tile of the player's colour is encountered, as shown in <xref linkend="block-shot"/>. The player can only take tiles that are a direct result of the placing a tile on the board. Once a tile is placed on the board the player cannot remove it and place the tile somewhere else. If a player cannot move they forfeit their turn. The game ends when it is no longer possible for either player to move. <figure id="block-shot">
221
<title>White cannot capture the black tile in the centre of the middle column because there are white tiles blocking the ends of that column. If it were black's turn instead, black could place a tile at the top of the column but would only flip the first of the two white tiles.</title>

<title>Player Colour and Difficulty</title>
242
<para>When you start <application>Iagno</application> the human player plays black and the computer player plays white with the first level of difficulty. Using the <guimenuitem>Game</guimenuitem> tab in the <guisubmenu>Preferences</guisubmenu> dialogue you can set the type of player for each colour. Human is of course you, level one is the easiest computer player and level three is the hardest. You can set both to human to play against a friend or set both to computer to watch the computer play itself.</para>

<para>This option is in the <guimenu>Settings</guimenu> menu. Then go to the <guisubmenu>Preferences</guisubmenu> submenu in the <guimenuitem>Game </guimenuitem> tab and it is initially off. When enabled this option makes the computer player place its tiles faster.</para>

<para>Enabling this option does not force the computer player to move and does not reduce the level of difficulty.</para>

<para>This option controls the amount of animation present when each tile is flipped, using radio buttons. Selecting the option <guibutton>none </guibutton> will cause the tiles to change colour instantaneously. Selecting the <guibutton>option</guibutton> partial will cause the animation to flip the tiles slowly. Selecting the <guibutton>complete </guibutton> option will cause the tiles to flip slowly and smoothly.</para>

<title>Stagger Flips</title>

<para>This option causes captured tiles along a row, column, or diagonal to flip one after another, like dominoes; instead of all flipping simultaneously. It has no effect on game play, but looks nice.</para>

<title>Show Grid</title>
301
<para>This option will display a grid on top of the playing surface. The grid is useful to display because it shows the player exactly where they are placing each tile.</para>
