Every game has its rules – the rules of checkers are very easy to understand. Firstly, the game is played on a chessboard by two opposing players. One player usually picks dark counters (twelve in number), while the other automatically chooses the lighter counters (also twelve in number).
The rule of checkers restricts a player from moving an opponent’s piece, and only the shaded squares on the board are used. There are usually 64 squares (8 x 8 alternating squares) on a chessboard; however, some chessboards have up to 100 squares (10 x 10 alternating squares).
To play the game, the players have to move their piece diagonally to the next unoccupied square. But if the next (diagonal) shaded square contains the opponent’s piece and the subsequent space is free, the player can jump over the opponent’s piece to the next free space and then capture the opponent’s piece (remove it from the board).

Note: You can only capture your opponent’s piece when it is in the next shaded square you were supposed to move to, and also, the subsequent square must be vacant (having no piece on it).
The core objective for playing draughts is to capture all your opponent’s pieces, which means you’ve won over your opponent. Also, when a piece is able to travel all through an opponent’s boxes (squares) without being captured, the piece turns to a “King,” which means more power; thus, the King piece can move forth and backward to capture an opponent’s piece. When a piece turns to a King, a previously captured piece can be placed on its top to distinguish it from the rest.
