Daily Sudoku: Killer & Jigsaw

Daily Sudoku Herald gives you one sudoku every morning, and the rule changes every day: classic, killer sudoku, jigsaw sudoku, sudoku X, thermo sudoku. Five variants take turns, in a game set like the puzzle page of a newspaper: paper, ink, and digits written in ballpoint. ONE PUZZLE A DAY • Every morning, a new numbered edition: the same number and the same rule for every player. • The difficulty follows the week: easy on Monday and Tuesday, medium from Wednesday to Friday, hard at the weekend. • Your very first daily puzzle is served easy, whatever the day. • A missed day is not lost: the last 60 editions stay open in the archive. FIVE SUDOKU VARIANTS • Classic sudoku: rows, columns and 3×3 boxes. • Sudoku X (diagonal): both main diagonals also hold the digits 1 to 9. • Killer sudoku: the digits in a dotted cage add up to the number in its corner. • Jigsaw sudoku (irregular): nine free-form regions replace the boxes. • Thermo sudoku: digits increase from the bulb to the tip. New to a variant? An illustrated rule card appears before the grid and stays one tap away during the game. FREE PLAY • Pick a rule, then a difficulty: easy, medium or hard. • Grids are generated on your device: play as many as you like. • A best time for each difficulty. SOLVING TOOLS • Pencil notes, eraser and undo. • A counted number of hints: 3 to 5 per grid, depending on the difficulty. • Timer with pause, and a mistake counter. • Autosave: close the app, your grid is waiting. STREAK, RANKS AND LOGBOOK • Your day streak sits at the top of the home page, and the archive keeps your best streak. • Five ranks, from Apprentice to Editor-in-Chief, that never go down. • A monthly logbook, stamped for every daily puzzle you solve. • A result summary that shows no digit of the grid, ready to copy and share. • An optional daily reminder, at the time you choose. COMFORT • A "night paper" dark mode that follows your device setting. • The grid is described cell by cell for screen readers. • Available in 14 languages. NO ACCOUNT, PLAYS OFFLINE No account to create, nothing to set up. Grids are generated on your device: the daily puzzle and free play both work with no connection, on the subway or on a plane. ADS, IN PLAIN WORDS The game is free and funded by ads. No banners, and no ad forced on you during a grid. In free play, an ad may be offered between two grids: it is announced first, and you can decline it. When you run out of hints, an optional short video gives you one more. See you tomorrow, for the next edition.
