Hi all,

I was wondering who else has undertaken to make improvements to the original Sudoku game, and what they were. So far, what I have done, is this:

  • Selection is saved always, e.g. Continue and Exit.
  • Settings can be changed from Game screen
  • Locking the original numbers
  • A setting to switch on or off locking (default on)

Another thing I was thinking of adding was a “Sudoku Generator” of sorts, that is, the capibility to generate new games on each level.

Anyone who would like to discuss these improvements & ways to implement them would be appreciated. For example, I use an additional array called “locked”, that I fill with the original puzzle string. Later in the game, I just have a method isTileLocked(x,y) return true if the corresponding value is non-zero. This is of course saved like the puzzle array.

I haven’t looked at it for months now, because I didn’t have much of a chance to work with Android since 2011. I just discovered Sudoku isn’t even installed on my phone anymore.

If you are patient, I’ll see what I can do. I can’t even remember exactly what improvements I made, but I did like the result ;-).


P.S. Could you kindly remove your other post in TDD for Embedded C. Although it did help to catch my attention, it’s rather confusing in the other thread. Thanks.
