Killer Aid app review

Wow what can I say about this app! It has been super helpful in giving me a better understanding of how to conquer certain sudoku puzzles! To be honest, I would usually be far too stubborn to download a separate app just available to complete puzzles, but I didn't want to give up on finishing some of these hard puzzles. I have been super impressed by how easy this app is to use and how quick the results are given. I guess that's why the developer decided to call it killer aid! It is definitely a killer sudoku helper haha! And, now I'm killing these sudoku puzzles.
