## What is Sudoku Journal?

Sudoku Journal brings eight sudoku variants into one ad-free app and keeps a journal of every puzzle you finish.

A PAGE FOR EVERY PUZZLE
Each puzzle you finish becomes an entry in your Journal. It shows the solved board, your time, mistakes and hints, and your average for that difficulty. Week, month and year pages gather your dailies, streaks and personal bests.

STICKERS
Collect multiple stickers for streaks, variety and clean solves. Some stay hidden until you earn them.

EIGHT VARIANTS, FAMILIAR CONTROLS
Play Classic, Jigsaw, Killer, Diagonal, Thermometer, Sandwich, Odd/Even, and Windoku. The board, keypad, notes, and guided hints work the same in every variant. Classic and Jigsaw also support quick 6×6 puzzles.

AD-FREE PLAY
Every puzzle is free of banners, pop-ups, and video interruptions. The free and paid options use the same ad-free app.

LOGIC-CHECKED PUZZLES
A logical solver checks every generated puzzle before it reaches you. Each puzzle has a path to the solution without guessing or trial and error.

DIFFICULTY BASED ON TECHNIQUE
Easy, Medium, Hard, and Expert reflect the techniques needed to solve a puzzle, not the number of given digits. Easy puzzles always offer an accessible next step. Expert puzzles require advanced techniques.

GUIDED HINTS
Guided hints help you find the next move. Tap again to see the answer. If 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. Completed challenges appear in your journal and count toward your streak.

OFFLINE PLAY
Open and finish in-progress puzzles without a connection. The app does not require an account.

FREE OR ONE-TIME ACCESS
The free app includes 14 puzzles a week across all eight variants, plus the Daily Challenge. Ticket packs add puzzles. Sudoku Journal Ultimate is a one-time purchase with 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 disable anonymous usage statistics in Settings.
