Puzzle scoring brings an arcade game feel to sudoku and provides a metric for challenges. Sudoku Book uses an exclusive method of scoring games based on the difficulty of each answer - not based on time. Now there are two parts to the puzzle, how to solve it and how to get a higher score.
We listen to our users and have added many features based on user requests. Tech support is available within the app as a direct email to the developer. And we respond. Already in version 3 we've been in contact with many users and are fixing things based on their input.
