WARNING: DOUBLE BLACK DIAMOND! (as in there are two diamonds as the theme in the grid, and that this puzzle is very hard)
This is a Friday Yin Yang puzzle, with the extra constraint that if you rotate the grid 45 degrees, the colored cells will form an extra valid 3×4 Yin Yang grid and a valid 4×3 grid too.
This wraps up my extra grid obsession on a very fun note. Next week I will start with “regional” puzzles.
Have fun 🙂
