Looks like carom can have one or two r’s, just as you like. But the real find here is Kik-It, which is a foosball-style game. This one looks to be from the early 1960s and from the pictures I’ve seen, it just had little pegs to kick the ball rather than little foosball players. As for crokinole, it looks like it is Canadian carom, just like Canadian bacon is not really bacon.
