* A player must take the opponent's piece when in a position to do so. This rule also applies to multiple moves. The computer will not allow the player to make another move until this has been completed. After crowning, a player is not permitted to continue a multiple move. 

Joining a Game
A game will not begin until two participants have joined. 
The first player to join the game is designated the 'leader' and uses the black pieces. The second player uses the white pieces. The black player starts the game. 

Moving Pieces
During their turn, each player moves one piece at a time. In order to move a piece on the board, the player must choose a piece using the mouse. The piece will be highlighted when the mouse clicks on it. After the piece has been chosen, the player must then choose the destination square . 
If an illegal square is chosen, an 'error' sound effect will be triggered. 
The sound effect will be deactivated when the piece has been chosen again. The cursor will change form when a legal destination square has been located. 

Taking Pieces
In order for an opponent to be defeated, the player must take the opponent's pieces. When a player takes the piece of an opponent, there will be an animation of the player's piece 'jumping' onto the opponent's piece. The opponent's piece will be in 'death-throes'. 

Replacing a Pawn with a King 
When one player's pawn successfully reaches the other side of the board, the pawn is replaced by the opponent's King. 

Concluding the Game
When a player wins a game, there will be a animation signifying the player's victory. At the conclusion of a game, the leader must choose 'New Game' to begin a new game. The leader also has the option of starting a new game at any stage of play.
