How this board opens
A first sweep of the overlap rule down the rows and across the columns settles 82 of the 150 cells, about 55%, which is enough of a skeleton to work outwards from. The most generous opening is column 1, which gives up 12 cells on its own. One of the 25 lines is decided outright by its clue, 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 46 cells, and the longest unbroken run anywhere in the clues is 10.
About this category
Mugs, umbrellas, light bulbs, scissors — everyday objects has the most varied dimensions of any category on the site: eight distinct grid shapes, from a 5×5 and the catalog's only 5×15 board right up to 15×20 and 20×20. Nothing else here covers that much ground, which makes it the natural category to browse when you want a particular size rather than a particular theme.
