Had the same issue, note that according to the docs, $

Matches the end of the string or just before the newline at the end of the string...

Just after I say this I do the Google search that finally leads me to an answer...

A 7 kyu I have no idea how to do even after looking through the cheat sheet, and coming back after a few days...

Spent longer than I like to admit on this before finally deciding to try the actual solution. Sometimes you just overthink things.

• I sometimes get a few failed tests like:

Youre RegEx should NOT match 'bxa6e1p1'
Youre RegEx should NOT match 'fxe3eNpN'

...but not always. Some of these should be added to the fixed tests.

• also, strings ending with +# and #+ should be tested
• +1 typo: Youre --> Your

So I was testing why my solution was timing out (can't honestly imagine how to make it faster) and I made it return just 0 and one of the advanced cases passed.

Is there really a case that requires 0 (wouldn't really make sense, per the description there is no way to make a case where 0 is correct result) or is this just some timer case that checks if you fit in the 1 second?

Same here (language: python).

Patience and coffee is the only way to solve this ))))

As @B4B already pointed out, this kata is a duplicate of https://www.codewars.com/kata/do-not-loose-at-tic-tac-toe. But that was 3 years ago and this kata has not been unpublished still now, so I was wondering what is the future of this kata, would it be unpublished eventually? Or remain in beta forever?

This one was painful. xD

Maybe TypeError("first argument must be string or compiled pattern") or re.error("Reason") are clear enough?

Afterall, user can see re.compile(REGEX) in sample tests.

Prolog: Solution expects a specific (unspecified) order, while description states that order is irrelevant.

Python, possibly other languages: tests miss sanity checks on values returned by user solution and crash badly when an unexpected value (not a pattern, or not a valid pattern) is returned.
