Crosswords 25x25 in XXL format

A 25x25 grid, the largest format on the site, and unlike every other category here, it isn't meant to be finished in one sitting, it's easy to come back to gradually, a little each evening, over several days. Another way to use it is as a shared game, the grid can be solved together with friends or family, taking turns on different sections, something the smaller formats don't really lend themselves to, since those are usually finished solo in one evening. It's the sheer volume and structure that make 25x25 a format built for patience rather than speed.
