Fantastic App

Great utilities for figuring out possible combinations. Great UI (the corner notes don't cover up cage totals like in your web
app. Only one nitpick, I seem to have a different difficulty scale than you guys. The first puzzle, rated one star, took me just
over 50 minutes because I just couldn't see

Not your average killer sudoku

Killer sudoku is my favorite sudoku variant, and when I heard Cracking the Cryptic was releasing their own app, I was thrilled. As
