Due to popular demand, we've added a new feature in v1.3 to create crosswords based on a list of words you provided. Hope you like it! Regarding only three grids, at the beginning we weren't sure what the usage would be, and because server time costs us money, we erred on the side of caution. We have since increased the initial limit to ten.

You're welcome! Right now it doesn't have that feature, but an upcoming version will allow you to save in progress, and resubmit. The latest feature lets you create crosswords from lists of words you provide.

Just FYI, the online version now supports 25x25. To get to it, go to Get More Crosswords on your iPhone or iPad, then enter an email address and select Pro. You’ll get an email with a link to online.We revised the backend to improve the success rate for larger crosswords while keeping the same computing limits.As a professional, you’re probably using it by sending multiple and picking the best of, so you might be happy to find out that we’re topping up every day now, so no need to buy crosswords any more.Hope you like the changes!——————————————A version which supports 25 x 25 crosswords is in planning, but the limiting UX factor is the size of the mobile screen. It’s already pushing the limit with 15 x 15. We do have a corresponding web interface linked to CWC which would be ideal to support 25 x 25, but precisely no one uses it! Related to this is that for large crosswords, the entries tend to include more phrases as opposed to single words. We’re currently investigating what’s available with respect to these kinds of word lists.Besides that, there are very different computational requirements in generating a 25 x 25 puzzle vs a 15 x 15 one, so we may need to revise our business model.In summary, we’re working on it!
