Sudoku Journal: Daily Puzzles

Sudoku Journal brings eight Sudoku variants into one ad-free app. EIGHT VARIANTS Play Classic, Jigsaw, Killer, Diagonal, Thermometer, Sandwich, Odd/Even and Windoku with the same controls. Classic and Jigsaw also have 6×6 Mini boards for shorter sessions. AD-FREE PLAY The free app and Ultimate both work without advertising banners or videos. LOGIC-CHECKED PUZZLES A logical solver checks each generated puzzle before you play. Difficulty depends on the techniques needed to solve it, with four levels: Easy, Medium, Hard and Expert. HINTS Ask for a hint when you get stuck. Guided hints help you find the next move, with a separate tap to show the answer. When a guided explanation is unavailable, the app can reveal a correct digit. DAILY CHALLENGE A new Daily Challenge is free each day and does not use your weekly quota. Complete it to build your streak. OFFLINE PLAY Play without an internet connection. You do not need to create an app account. FREE OR ONE-TIME ACCESS The free app includes 14 new puzzles a week across all eight variants, plus the Daily Challenge. Sudoku Journal Ultimate is a one-time purchase for unlimited puzzles and access to current and future variants. PRIVACY CONTROLS Sudoku Journal does not track activity across apps or sell personal data. You can turn off usage statistics in Settings. Support: [email protected]
