Six-Cell Window
Expert
Used by Smart Hint
The same block check widened to a 2x3 or 3x2 rectangle — six cells at once. Slower to work through, but it catches clue clusters that bend around a corner, which no straight-line or square window can see.

How it works
- Same idea as the Quad Window, stretched to a 2x3 (or 3x2) rectangle — six cells checked as one.
- The wider shape has TWO fully-enclosed middle dots instead of one, and it can hold a cluster of clues that bends around a corner — a shape no square block and no straight three-in-a-row can cover.
- Working through six cells by hand is real effort, which is why this sits near the top of the ladder: try everything cheaper first, and only widen the net when nothing else moves.
- As always, any edge that comes out the same way in every surviving combination is forced — drawn in if it's always a line, X'd if it's never one.
