Halifax Kakuro

Halifax Kakuro as an app

The online puzzles can also be installed as an app on your phone, tablet or computer. This is a great way to keep puzzling when you are offline.

There is nothing to download from an app store, and no account to make. The app is the same as the website, just installed as an icon on your home screen. It updates itself: when there is a new version, you get it the next time you start the app. And it is of course free!

Playing offline

The app can also be used offline. Whenever you are online, the app downloads a supply of daily puzzles as well as some random ones. So even when you are offline, you can still do yesterday's puzzle, look ahead to next week, or ask for a random puzzle.

Of course, puzzles you are working on and puzzles you have already solved also stay on your device.
