Technical details (casual players probably wouldn't be interested):

- The solver does not inform you of whether the sudoku puzzle you asked it to solve has a unique solution.
- Hints, by design, are "minimal," that is, it purposely only does a one-pass check for possible values. Otherwise, what fun would it be if we tell you what the solution is for each box every step of the way? :) (though for easy puzzles, that's what the one-pass check does anyway)
- While most 16 by 16 puzzles takes only a few seconds to solve, some could, in theory, take minutes given the possible solution space (e.g. worse case 16^256 = 178 * 10^308 possible solutions!). So, please be patient!
- The solver is by definition computation heavy. To save your battery and wait time, the 16 by 16 puzzle solver requires having at least 48 of 256 squares filled in.
- While the solver has been stress tested and verified on over 290 million puzzles, one can never be certain of the correctness in all possible 9x9 or 16x16 sudoku puzzles. If you find any issues with the solver, please let us know, and we will correct it right away.
- The INTERNET permission is required for facebook integration. The WAKE_LOCK and READ_PHONE_STATE are needed to prevent screen from sleeping and to mute the background music if you get an incoming call.

And if you do love it, please rate it 5 stars and tell your friends! Greatly appreciated!
