Been using Sven’s SudokuPad for a couple months now. It’s basically a Sudoku app that lets you play the same puzzles used in the Cracking the Cryptic YouTube videos. Pretty solid app if you’re into Sudoku.
Here’s what you do: you can create your own Sudoku grids or try out the exclusive puzzles made by the Cracking the Cryptic guys. There’s also a hint system if you get stuck, which is pretty cool. And you can track your progress and time – took me a while to figure that out but it’s useful.
Look, if you’re into Sudoku, you’ll probably like this. It’s not perfect – the hint system could be better and there’s some ads if you don’t pay – but overall it does the job. Worth checking out.
