What are the rules for each checker piece?

In checkers, each player starts with 12 pieces, which move diagonally on the dark squares of the board. Regular pieces can only move forward one square at a time and can capture an opponent's piece by jumping over it to an empty square directly beyond. When a piece reaches the opponent's back row, it is "kinged" and crowned, gaining the ability to move both forward and backward. Kings can also capture by jumping over opponent pieces in either direction, making them more versatile on the board.
