This is the best Sudoku game in town. Please update to iOS 11! – Big Bad Sudoku Book Review

I have been playing and enjoying this game for several years. Thank you very much for creating it! However, it has not been updated so won't be compatible with iOS 11. Because of this, I have researched similar games in the AppStore. Nothing comes close! So I have decided not to upgrade my iPad just because I don't want to lose this specific game. I know right? Life is indeed stranger than fiction. Lol. Seriously though, please update!! Thank you.
