How to play Checker?

Starting the Game
To start a new game, press MenuBar and select "New" button. You also can select 
first move or last move if you press MenuBar and select "Swap".

Moving Pieces 
Select you piece, if the piece can be moved according the game's rule,  it will
become meshed graph. If you change your mind, you can select another piece for 
movement by clicking it. Then you can select position where you want to move, if 
the position can not be moved to, the selected piece will be no answer, otherwise
it will be moved to the position you selected.
If your move was a simple move or a single jump, the computer will then make its 
move. If your move was the first jump in a multiple jump, then your turn will 
continue. Select subsequent jumps in the multiple jump in the same way you 
selected the first. 

Crowning Pieces
Pieces will be crowned automatically when they reach the opposite side of the board. 
Crowned pieces are indicated by marking a "K". 

Ending the Game
The computer will announce the winner automatically. The game ends when one player 
has either captured or immobilized all of the opponent's pieces.

The rules of Checker

The Game
Various forms of Checkers have been around for thousands of years, but the game as
we know it appeared several hundred years ago. The object of the game is to either 
trap or capture your opponent's playing pieces. The game is played on an eight by 
eight checkered board with alternating light and dark squares. Each player begins 
with 12 game pieces arrayed on the squares directly in front of him. 

Basic Movement
The human player moves first regardless of the color chosen. Pieces must move 
forward along the diagonals. 

Capturing Pieces
When you "jump" an opponent's piece, it's captured and removed from play. A piece
can be captured when: 1) it sits on a square where your piece may have validly moved 
if that square was vacant, and 2) the square on the diagonal beyond the target piece 
is unoccupied. 
An important point of strategy is that you must jump when given an opportunity. If 
there's more than one jump possible, you may select the one you want. You can use this
rule to manipulate your opponent into an uncomfortable position by sacrificing one of 
your pieces. You may also make multiple jumps by jumping several of your opponents 
pieces in one turn. The multiple jump must be made by one of your pieces, and you must
complete the jump - you can't stop in the middle of the sequence. It is possible to 
jump your way to the edge of the board, crown your piece, and continue jumping back 
the other direction in one move. 

Crowned Pieces
When a piece reaches the opposite side of the board, it's said to be "crowned". Once a
piece is crowned, it may move both forward and back along the diagonal by one square,
making it exceptionally powerful. Any piece may capture a crowned piece, however. 

Determining the Winner
The first player to either capture or immobilize (leave without a valid move) all 
the opponents pieces is the winner.
