In Bowls, the balls are slightly oblate, with the oblateness being
different in each hemispheroid. But they don't call them "balls".

I've seen juggling balls that are more cubical than spherical. But I
don't know whether anyone uses them in a competitive sport.
For that matter, the dimples on golf balls are an important part of
their shape.

I'm not a mathematician so I don't know for sure but
can a quoit (torus) be considered an n-dimensional ball?
(I don't know what value n might have)

No. It's topologically distinct from a ball.

Name 5 sports/pastimes that use a net but no ball.
It cannot be a safety net so things like discus and trampolining are not
allowed.

Wouldn't the nets in bee-keeping be for safety then ?
Badger baiting sounds dubious too. I've seen nets used for catching
rabbits out of a warren, but sacks for catching badgers...
Hell, if they're allowed, then I'll add 'fruit cultivation' - that

You can play gladiators with balls, but most jugglers prefer

Well, most people seem to get the first three.
Badminton, fishing and ice hockey.
It's the other two that are tricky, and they are....
deck tennis which is played on ships with quoits instead of a ball and
no raquet.
and
shuttlecock where you use your feet to hit a disk with a feather over a net.

Snooker and Billiards. There is a net in the pockets which guides the
balls down.

Good answer. I don't know of any balls at all used in billiards or snooker.
Unless you count the 16 on the table.

22 Balls in Snooker, 3 in Billiards...
*Pool* (or 8-ball?) uses 16 balls, which may be what you were thinking?

A fifth answer is ringette, a game that resembles ice hockey played with
a hard rubber ring. See:
I first encountered the game when I saw scores for it reported in the
sports pages of the Helsingin Sanomat and had to pull out my
Finnish-English dictionary to make sure this wasn't an alternative name
for ice hockey.

Both "pool" and "billiards" are also used generically as terms for any of
these and similar games (although, obviously, not by everyone).

Snooker uses 23 balls:
15 red balls,
7 balls (#2 ---> #8),
1 cue ball. _________________________________________________Gerard S.

Carom is a very good game, at which I am passable, but could you call it a
sport? No more than Tiddlywinks.
But you remind me; it's stretching the point a long, long way, but the cars of
NASCAR typically have nets over the driver's side window, do they not? I don't
know if it's a safety feature, but I doubt it; it's insufficiently substantial.

Yes the nets over the window in touring car type racing is a safety feature.
Its there for when they roll their car so that their arms/head don't fly out
the window

Again, defining "balls" loosely, I am surprised that horseshoes and
curling have not yet been mentioned here (unless I missed them or they
have not yet appeared on Google).
But, unseriously, almost no balls are (perfect) spheres, due to low
air-pressure in some balls, or due to the balls sometimes moving at
relativistic speeds in relation to their observer...
Thanks,

In sport kiting there are kites designed for usage in high winds that
have some of the sail panels replaced by netting. Thus retaining the
structure and dynamics of the kite design but allowing some of the air
to escape through the sail.

For objects that would typically be called a "ball", a bowling ball has
those finger holes cut out of it. It could then be called intentionally
non-spherical.

Well, for that matter, golf balls have (inward) dimples, baseballs have
threads, soccer balls have seams, so do volleyballs, basketballs have seams
and (outward) dimples, etc., etc. The closest to speherical ball I can
think of is a ping pong ball.

I would expect the most exactly round balls to be solid, hard ones, such
as billiard balls.

A ping pong ball has a seam. Ask anyone who has broken one in half.
Maybe the professional ones don't....
A racquetball is also fairly close to spherical, except in play.

True, and the seam forms a ridge, but the best-quality balls have a spherical
exterior, if not a smooth interior. Poor-quality balls are little more than two
rough and misshapen hemispheres crudely melded.
