How this board opens
The overlap rule is stingy here: one sweep of it across every row and column yields 46 of the 225 cells, 20%, so most of this board has to be argued for rather than read off. The most generous opening is row 1, which gives up 11 cells on its own. Straight line logic carries it to 217 cells and then stalls, so the last 8 need cross-referencing between a row and a column that share a cell. The finished picture fills 84 cells, and the longest unbroken run anywhere in the clues is 13.
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.
