Show HN: World's Biggest Crossword App

Hi, we (two man company) have just release what we think is the world's biggest mobile crossword (single grid of 103x103) for iOS and Android. It plays pretty well all the way down to iPhone 5 (a wee bit small to be honest!).

Looking for any feedback especially around any novel (read cheap) ideas on the marketing/promotion front.

The retention on the app is awesome once people get started, but as it is a single grid the life time value is pretty limited. I think part of the appeal is the fact you can finish it so it is a mixed pleasing.

Cheers, James

ps - we are UK based, but we have made quite a lot of effort to avoid / callout where it is a UK term/spelling.
