Sudoku Daily: Jigsaw & Killer

"Every morning, a grid. And every morning, a different rule." Someone had to put sudoku back in the newspaper. The Daily Sudoku looks like the puzzle page of a broadsheet printed for you alone: the grain of the paper, lines drawn with a nib, digits laid down in ballpoint. Beneath the styling, one simple and formidable idea — the rule changes every day. THE IDEA One day, a classic sudoku to warm up. The next, diagonals. Then killer cages, irregular regions, thermometers. Five variants take turns across the editions, and the difficulty follows the rhythm of the week: gentle on Monday, stern by the weekend. Every grid carries its issue number, like a newspaper — and it is the same grid for every player, everywhere, on the same day. Never played a killer or a thermo? A clear rule card appears before each variant and stays available at any moment. That is what makes the exotic rules approachable — and what makes you come back for the next one. WHAT WE LIKED — How legible the constraints stay: cages, thermometers and regions never obscure a digit. — The streak on the masthead: your days in a row are printed at the top of the paper, and the archive keeps your best run. That is what brings you back. — The ranks, from Apprentice to Editor-in-Chief, which never go down — not even the day a streak breaks. — The emoji result summary, copied in one tap, ready to paste wherever you like. — The archive: the last 60 editions stay open. A missed day is never lost.
