Sudoku.com by Easybrain is essentially the definitive version of Sudoku for mobile. It avoids the clutter found in many other apps and focuses on what matters: the puzzle. The 'Note-taking' feature is particularly well-executed, automatically updating your possible numbers as you fill in cells, which removes the tedious bookkeeping of paper puzzles.
The app scales beautifully for all skill levels. If you're a beginner, the 'Auto-check' and 'Highlight Duplicates' features act like training wheels. For experts, the 'Expert' difficulty and 'Fast Mode' provide a legitimate challenge. The Daily Challenges and Seasonal Events (like the current Dragon Dance) give you a reason to log in every day. While there are ads, they are relatively unobtrusive compared to other free puzzle games, and the overall polish makes this my go-to app for my morning brain workout.
