How this board opens
A first sweep of the overlap rule down the rows and across the columns settles 76 of the 225 cells, about 34%, 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. 2 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 73 cells, and the longest unbroken run anywhere in the clues is 10.
About this category
Buses, cars, a taxi, a truck, a gearshift, trains running into a tunnel, ships from a small fishing boat to a modern hull at a dock, a sextant, a suitcase, a hotel reception desk, and the signage that surrounds all of it — a stop sign, a parking sign, traffic lights, the pictograms on a washroom door. It is the shelf of getting somewhere, and it is built almost entirely from objects that were designed to be recognised quickly.
