Solution 7 should be correct. The diagonal of -1s is a valid win.

Hope all is well with you, Doug!

Ned Gulley on 17 Oct 2017

@Sean, I think Doug's got it right. He's asking only if the X side (that is +1) is in a winning position. In test 7, the O side (-1) is in a winning position. So the answer given is correct.

Test 7 should return true. There is a diagonal of -1.

No. See Ned's comment and read the problem description again.

Shouldn't Test 7 be y_correct = 1?

To be fair, you didn't mention anything about anti-diagonal in your problem description (test no. 4). Or am I missing something?
