How this board opens
The overlap rule is stingy here: one sweep of it across every row and column yields 18 of the 225 cells, 8%, so most of this board has to be argued for rather than read off. The most generous opening is column 8, which gives up 15 cells on its own. One of the 30 lines is decided outright by its clue, with no room to slide. Straight line logic carries it to 61 cells and then stalls, so the last 164 need cross-referencing between a row and a column that share a cell. The finished picture fills 82 cells, and one run in the clues is 15 long — near enough the full span of a line that it fixes itself the moment you reach it.
About this category
Dice, pawns, chess pieces, playing cards — board games is a tighter, more consistent set than most of the catalog: ten of its thirteen puzzles sit right at 15×15, with only a couple of 10×15 boards and a single 10×10 on either side. That consistency is deliberate rather than a gap. Once you're comfortable with 15×15 solving here, every other puzzle in the category feels familiar rather than like starting over at a new difficulty tier each time.
