How this board opens
The overlap rule is stingy here: one sweep of it across every row and column yields 68 of the 400 cells, 17%, so most of this board has to be argued for rather than read off. The most generous opening is row 1, which gives up 20 cells on its own. 3 of the 40 lines are decided outright by their clues, with no room to slide. Straight line logic carries it to 68 cells and then stalls, so the last 332 need cross-referencing between a row and a column that share a cell. The finished picture fills 117 cells, and the longest unbroken run anywhere in the clues is 12.
About this category
Hats and masks make an unusually top-heavy category: most of it is full 20×20 boards, the rest sits at 15×15, and there is a single 10×10 as the only real warm-up. Proportionally that makes hats & masks the most 20×20-heavy set on the whole site — if you specifically want the big grids, there's a higher concentration of them here than anywhere else, the larger food & drink category included.
