No worries!

Thanks for the quick reply and closing the Issue - hope you enjoy your time on Codewars, and congrats on solving (just saw your profile was updated - I saw you had a little typo with board vs row ;) ).

By the way, there is a Discord if you want to join (link is in sidebar on the left), that's normally the best way to get a quick reply especially on weird timezones/weekdays depending on who is online.

you're totally correct, was looking at the wrong log. whoops! appreciate the help.

Hey and welcome to Codewars - this test/board is indeed a correct Sudoku, so I'm guessing that you are reading the error logs/console incorrectly

The "Expected True to be False" is applying to the board above the error message - try reading this troubleshoot page then re-run your tests; make sure you are taking the sample test input from "above" the failed error message.

I won't close issue for now, but please update if that was indeed the problem.

random test (below) failing, wants a false. tested manually and on a sudoku solver, the board is correct. it should be true, but expects a false.
