What does this mean?

"E" if an error of any kind occured during the interpretation (invalid input or invalid move required)

How do we know who made an error? If someone does not have a legal move, can they make an "invalid" illegal move? Or is the turn flipped and the other made the error? And what if both players don't have a next legal move, and there still is a move in the input, who made the error?

well, it depends how you interpret the description I guess. The description should either:

• state the exact rules, with examples
• OR tell us that it's a prerequisite that we known the rules, and link us to the proper rules somewhere online

I watched a quick guide of the rules. For instance, the statement below is incorrect. You can't flip any pieces in between, you can only flip from the piece you place to your first own piece.

A player can play only if he has a valid move. Valid moves are those in which an opposing piece is trapped (horizontally, vertically, or diagonally) between one already on the board, and the piece being placed. Any pieces between will be flipped (could be more than one!).

For instance

BWWBWW

-> if you place a B at the right, you end up with

BWWBBBB

k i will change it

I think it does, else I would not have given you these specific instructions. But it's up to you to keep it or change it.

shouldn't matter too much

no thats just what i did

Seems pretty different to me

How much is this different from this kata?

I don't know if it's just the description, or also test case generation that is incorrect here

The Coffeescript version is definitely broken. It appears that when the "Random Test Cases" are performed, the preloaded "words" array only contains one word ([ "ZONES "]).
