Hint 2 of 2
The missing tile must continue the four-fold pinwheel pattern; match the orientation of the dark corners and pink star to the neighbours.
Show solution
Approach: match the missing tile to the surrounding pattern
- The wall is built from a repeating tile, rotated in a pinwheel; the hole sits where one tile is missing.
- Read off what the neighbouring cells demand at the four edges of the hole.
- Only choice E has its dark corner and pink-star orientation matching every neighbour, so it completes the wall.
