How this board opens
This one opens itself. One sweep of the overlap rule — every row read against its clue lengths, then every column — is worth 257 of the 400 cells, 64% of the board, before you have deduced anything of your own. The most generous opening is row 1, which gives up 20 cells on its own. 13 of the 40 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 89 cells, and the longest unbroken run anywhere in the clues is 6.
About this category
The smallest of the newer shelves and the most mixed. Some of it is the equipment: a baseball, a bowling ball and its pins, a rugby helmet, a kettlebell, a bicycle, a ski, a karate belt. The rest is what happens afterwards — a trophy, a medal, a chequered finish, and the numbered places on a podium. Worth knowing before you browse, because a fair part of the shelf is awards rather than sport, and if you came for equipment specifically there is less here than the label suggests.
