n. — Games
a board game in which wooden discs are flicked towards the centre of a board (see Image 1).
Type: 5. Frequency — In this game, the objective is to place one's disc at the higher-scoring centre of the board, while also displacing the opponent's discs. The Canadian origin seems most likely (see, e.g. the 2015 quotation), yet the earliest quotation is from Milwaukee from 1885 (see OED-3, s.v. "crokinole"). As Chart 1 shows, the term is most frequently used in Canada.
See also COD-2, s.v. "crokinole", which marks it "Cdn.", and OED-3, which marks it "Chiefly Canad.".
