Checkers (Draughts) is a classic two-player abstract strategy game played on an 8x8 board. Players move their pieces diagonally forward, capturing opponents by jumping over them. When a piece reaches the far row, it becomes a king and can move backward. The goal is to capture all opponent pieces or block them from moving.
Square size: 4.5-5 cm. Pieces: cylindrical, 3-4 cm diameter, 5-9 mm height.
Red moves first. Players alternate turns. On each turn, a player must make exactly one move.
Move one piece diagonally forward (left or right) one square to an adjacent vacant dark square.
Move one piece diagonally forward or backward (left or right) one square to an adjacent vacant dark square.
Jump diagonally forward over one adjacent opponent’s piece (man or king) to land on the vacant square immediately beyond it. The captured piece is removed after the jump sequence is complete.
Same as capturing move of a man, but may jump forward or backward.
If a jump creates an immediate further capturing opportunity, the piece must continue jumping until all possible captures in that sequence are completed. All captured pieces are removed at the end of the sequence.
When a man reaches the farthest row (king-row/crown-head), it becomes a king. Place a same-colored piece on top of it. This completes the turn – the newly crowned king may NOT continue jumping until the opponent has moved.
All captures are compulsory. If a capture is available, you must take it. If multiple capture paths exist, you may choose any one (not necessarily the one capturing the most pieces). Once started, a multiple jump must be completed.
The game is won by the player who makes the last legal move. This occurs when:
A player also wins if the opponent resigns, forfeits, or fails to meet time control.
A draw may occur by agreement, or under tournament rules such as:
Piece movement:
| Piece | Ordinary Move | Capture |
|---|---|---|
| Man | 1 square diagonal forward | Jump forward over 1 adjacent enemy to vacant square |
| King | 1 square diagonal any direction | Jump any direction over 1 adjacent enemy to vacant square |
