There is no equivalent in any other sport. It’s kind of like shooting par in golf with opposing players defending the holes.

A 147 in snooker is pretty impressive (although it's no no-hit perfect game).

This one by Ronnie O'Sullivan is very beautiful particularly the shot at just over 7 minutes:

And this one is the fastest 147 ever (again by Sullivan when he was younger)

Again, not to be compared to a no-hitter but they're much shorter to watch ;-)
