This is genius :). I definitly didn´t think about flattening the structure and test the positions string-wise. Would you have documented your intention a bit I would have tagged as Best Practice, for sure.

I only tagged as Clever because Genius doesn't exist ;).

what's going on here.. looks clever tho

Far for best practice, as it isn't understandable at first glance. On the other hand, a one-liner for a relatively complex task is cool!

great solution

Practically, don't think this will ever need to be scaled. It's tic tac toe. If possible future scaling isn't an issue, why even bother future proofing it?

I had to work that one out myself. Excellent

No doubt it is clever, never knew you could do it like this. Thans

nice

Nice

Do I understand correctly that it works only if the step is equal to half the alphabet length?

Wow.

Its clever, but is it the best practice?

oh thats spicy

@rowcased Thanks, I'm surprised that replies to solutions are accessible to people who have not solved them yet. It should be obvious that all comments to solutions are going to spoil the solution in one way or another, and people who have not solved the problem don't have any reason to read these solution replies anyway. Codewars should just hide every comment which replies to a solution as spoiler.
