About this board
The 5 in the bottom-left corner is the only patch you can place with certainty at the start, and it runs up the whole left edge. The tall shape-only clue in the top-right corner is settled by elimination: any longer patch there would leave a neighbour with nowhere to go. The square 4 and the 6 settle in the middle, and a wide clue finishes the bottom row.
