Would be good to mention in the description that input list may go in the form of list of strings, like this:

[['[0,0,2]', '[0,0,0]', '[1,0,1]']]

Each moves first in turn, doesn't he?

Very nice, seems easy at first, but then you try to find what is not working

I have an issue with 'dangerous inputs' too.
"4 should equal 0" or "-1 should equal 0".

What does it mean? Test tries to pass only (4) or only (-1),
while the function needs two parameters (level,button)?

But in my code things that are not 0,1,2,3 do give 0.

Shall the first argument be divible on sum of rest or on every each argument?

I get try again: [1, 4, 3] should equal [4, 3, 1].
But what is the difference?
