Sereno Sudoku: Offline Classic

Sereno Sudoku is sudoku built for playing without rushing: large, clear digits, a clean design, and nothing to distract you from the board. It is now three logic games in one app: Sudoku, Killer Sudoku and Nonogram. • Classic Sudoku in three difficulties, easy to hard, always with a unique solution • New: Killer Sudoku, the one with sums. Three levels with 120 puzzles each, every one with a verified unique solution and no given digits, the way the genre is meant to be. Included, no purchase needed, with its own "How to play" guide • Nonograms (picross): pictures you uncover with logic, with large numbers • Daily Sudoku challenge with a monthly calendar and streak. Play today's or catch up on any day you missed • Notes with automatic clean-up and unlimited undo. In Sudoku, hints show you the technique instead of just filling the cell • Number-first mode: pick a digit, then tap the cells where it goes • Row, column, box and matching-digit highlighting so you can read the board at a glance • Three themes: light, sepia and dark. Adjustable digit size • Optional original music, relaxing and unobtrusive • No lives, no energy, no waiting. No forced ads mid-game: the only ad that shows up on its own comes after you finish, and videos for an extra hint are always your choice • In English, Spanish, Portuguese, French, German and Italian • Works completely offline, no account needed Premium (optional, one-time purchase) gives unlimited hints, unlocks the dark theme and removes ads. Family Sharing supported: buy it once and share it with your family. A game by Vossen.
