Most Sudoku apps bury the puzzle under forced ads. Sudoku Infinity has none. The only ads are optional ones you choose to watch.
It also goes deeper. Six difficulties from Easy to Abyss, where Abyss serves true 17-clue puzzles, the fewest a Sudoku can have and still be unique, a challenge you rarely find.
Speed, Zen and No-Mistake modes, daily and weekly challenges, leaderboards, achievements, themes, cloud save, and full offline play. A Sudoku that respects your focus, not your attention.
