Never heard of crokinole, Jackie. But from what you say it appears to be quite different from Carom (at least as I know it).

A Carom board is a square, highly polished, wooden board with holes in all four corners that have small collection baskets tagged on underneath. The centre of the board is marked for a solitary red disc and eighteen white and black (nine each) are arranged in an alternating fashion in concentric circles. Either two or four players can play. Each player shoots a disc (called a striker), in turns, at the central arrangement of discs, with the aim of landing them in the corner holes. Whoever gets the maximum number of discs in, wins. Red scores highest, followed by white and then black.

Have you played this?
