A while ago I released an updated version of my Sudoku Solver iOS app. As well as solving regular Sudoku puzzles it can Sudoku puzzles ‘with a twist’ (where there is a ‘twist’ of nine shaded squares which must also contain the numbers one to nine). What’s more, if a particular puzzle has multiple solutions it will list them for you. The latest version also has the ability to store and retrieve puzzles, and I have improved the user interface.
In reality I can’t see many people wanting to use it – it’s not the only Sudoku solver out there, and what’s the fun in using an app to solve a Sudoku puzzle anyway? – but I enjoyed writing it and I was curious as to what the whole process of writing and publishing an iOS app was like.
To find it just go to the Apple App Store and search for ‘Vaughan Harper’ (or else look at https://apps.apple.com/us/app/sudoku-solver/id1349979694 ).
I’ve attached some screenshots below.
Clearly this isn’t going to solve the world’s greatest problems, but it was a lot of fun writing it.
