How this board opens
Nothing falls out of this one for free: a first sweep of the overlap rule down every row and across every column leaves all 100 cells open, so the board only starts moving once you play rows and columns off each other. Straight line logic carries it to 0 cells and then stalls, so the last 100 need cross-referencing between a row and a column that share a cell. The finished picture fills 31 cells, and the longest unbroken run anywhere in the clues is 5.
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.
