Electronic Sudoku

Jan 24, 04:46 PM

I prefer to solve on paper, but I sometimes find myself with downtime while standing in line somewhere, so I keep a sudoku application on my phone to play with. I have tried a number of programs, but my favorite one is OpenSudoku for Android for a number of reasons.

My favorite feature of this particular sudoku implementation is that it supports 3 different input mechanisms. Depending on which phase of solving I am in, different entry methods are faster. OpenSudoku allows me to quickly switch between them, making entering numbers satisfying and joyful (as it should be) instead of a chore.

The other fantastic feature that this one has is its support for importing more puzzles. The format is dead simple, and I have even started to encode some of my favorite puzzles for reference and practice.

Are there any others that you like?

  1. One of your puzzles in your favorite puzzles list is invalid (it has 2 3s in box 4):

    Thanks for the list of good puzzles.
