How this board opens
A first sweep of the overlap rule down the rows and across the columns settles 75 of the 225 cells, about 33%, which is enough of a skeleton to work outwards from. The most generous opening is row 15, which gives up 15 cells on its own. 4 of the 30 lines are decided outright by their clues, with no room to slide. From there the board finishes on row-and-column logic alone — there is no point where you have to try a cell both ways and see which one breaks. The finished picture fills 79 cells, and the longest unbroken run anywhere in the clues is 8.
About this category
Weather and the seasons, mostly: rain falling, a cloud with sun behind it, wind as curled strokes of moving air, a snowdrop pushing up through the ground, summer rays, the bare tangle of roots, an umbrella, a pair of sunglasses, a thermometer with its three scales, a campsite. It is the shelf with the fewest man-made objects on it, and it behaves differently from the rest of the catalog because of that.
