Extra large crosswords 23x23 on the site

A 23x23 grid is built for those willing to spend more time on it than even the large format allows, the field covers a noticeably wider vocabulary range and less obvious, more elaborate word crossings. This isn't a puzzle to squeeze in between other tasks, it's more of a whole evening's occupation, unhurried and clock free. What sets it apart from the giant format is that a 23x23 grid can still be finished in one evening, rather than stretching across several days the way the site's largest grid often does.
