Checkers, also known as draughts, is a board game played on an 8x8 checkboard. It is played by two people, on opposite sides of the playing board, alternating moves. At the beginning of the game, each player has 12 pieces, positioned on the first 3 rows of each side on the black squares.
- First move is made by the player with black pieces. There are two ways to move a piece: simply sliding a piece diagonally forward to an adjacent and unoccupied dark square, or "jumping" a piece of the opposing player. It is possible for a piece to be "jumped" if on one side there is an opposing piece and the opposite side is vacant. In this case, one piece would "jump over" the other into the vacant square on the opposite side. A piece that is jumped is captured and removed from the board. Multiple-jump moves are possible if when the jumping piece lands there is another opposing piece with a vacant square on the opposite side. Jumping is mandatory and cannot be passed up to make a non-jumping move, nor can fewer than the maximum jumps possible be taken in a multiple-jump move. When there is more than one way for a player to jump, one may choose which sequence to make, not necessarily the sequence that will result in the most amount of captures. However, one must make all the captures in that sequence.
- If a player's piece moves into the kings row on the opposing player's side of the board, that piece is said to be "kinged" and gains the ability to move in both forward and backward directions. If player's piece jumps into the kings row, the move terminates (it cannot jump out (as in a multiple-jump move) until that move has ended and the piece has been kinged).
- A player wins by capturing all of the opposing player's pieces, or by leaving the opposing player with no legal moves.
