1 Answer 1


I believe the answer is

Option 3, one black diamond

My reasoning is:

Each row and each column has two black diamonds and two white diamonds. Option 3 completes the pattern.

  • $\begingroup$ @TylerSelden I have not, but with the row and column patterns being this strong, that felt like overthinking it. $\endgroup$

    $\begingroup$ @samm82 Interestingly the columns are all "repeating patterns" in some sense: WBWB, BBWW, and WBWB. $\endgroup$
