> There's a rope around the field, if the ball goes over it without hitting the ground (like a home run) it counts for 6.

On the larger grounds, it tends to be a decently-sized foam triangular prism (covered in advertising, obvs.) rather than a plain rope which leads to "if it hits the triangle" rather than "goes over the rope" (I believe "hits the rope" also counts but is much harder to judge for obvious scale reasons.)

Also, IIRC, the ball can go over the boundary without hitting the ground but a fielder can knock it back inside for a catch to be performed to get the player out[0].

Sorry, I'm just making this more complicated for the baseballers, aren't I?
