The game was invented by the French settlers of Quebec, Canada; it was named Grand jeu de dames. It is unknown when the game was first played in Canada. The huff rule was dropped in 1880 after a dispute developed during the Canadian championship match.
The idea of an increased-size international draughts game is older still; boards with 12x12 squares were on sale in London in 1805.
Canadian checkers follows the same rules and conventions as international draughts, the only differences are the larger gameboard (12x12 squares instead of 10x10), and more checkers per player (30 instead of 20). The starting setup is shown in the diagram.
Games are recorded using the same method of notation used by other draughts variants, extended for a board of 144 squares (see diagram).
