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.
Generally, crokinole is a much less punishing game than carrom, if we're talking about Indian carrom boards. American carrom boards, that were really popular in after-school programs when I was growing up, have relatively HUGE pockets than the Indian boards, in addition to being smaller boards. American carrom is like playing 8-ball, Indian carrom is like playing snooker.
I like carrom a lot, but I'm terrible at it. I'm at least a reasonable player at crokinole, and it's a lot easier to introduce others to the game without them getting too frustrated by it.
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
