how do you turn any four digit number to a single digit number using one unchanging rule?

for instance
1000 goes to 3
2000 goes to 3
9000 goes to 4
8000 goes to 5
1234 goes to 0
4321 goes to 0

You should be able to do it in your head

If it's the rule that I think it is, 1234 and 4321 should be 1, not 0... Hmmm...

And, this is not really a lateral puzzle, is it?

By counting the number of "circles" or "loops" in the numbers.

P.S. It is a lateral puzzle since you have to make the mental leap of not thinking of it as an arithmetic problem. Well... at least not THAT kind of arithmetic problem.

I'm with Doriana. Requiring lateral thought doesn't automatically make something a lateral puzzle. You shouldn't be able to deduce the answer on your own without back and forth (in the form of yes/no questions) with the puzzle host.

But, welcome to the forum, Chook! I'd suggest taking a look at other puzzles on the forum to get an idea of the kinds of puzzles we do here.

I disagree, being able to deduce the answer on your own simply means the puzzle had (a)enough information or (b)it was easy. Every so often people get the answer right away even if neither of the above conditions was true. And there are plenty of questions that somebody could have asked the Original Poster if they didn't immediately see the solution.

My only problem is with the last sentence, I don't get it. If I can solve it immediately, in my head, there's no puzzle. If I cannot, can I ask questions?.. In the end, I'll stick with Doriana and Noel... Solving an equation might require a LOT of lateral thinking, but it is not a puzzle

Just to settle the matter I'll say we have a SPOILER.
