Growing up we called it Carrom board, which is square board with 4 pockets in the corners. I never knew there was an American version of it as Crokinole board.
Canadian. I haven't played Carrom, but it's my understanding it's Indian in origin and plays a bit more like a billiards variant, even going so far as to use tiny pool cues.
I haven’t played in a while but as long as I remember, there aren’t any pool cues but there are varying (house) rules on how/where the disc can be flicked
