Sudoku Sagax vs Murder & Method

Sudoku Sagax is Sudoku with real progression: solve levels, collect points and stars, climb through 19 fox ranks and take on everyone else in the daily challenge. Nona the vixen shows you around and explains every new puzzle type in half a minute. ELEVEN PUZZLE TYPES • Sudoku in four difficulties, from Easy to Extreme • Killer Sudoku, Kakuro, Nonogram, Crowns, Binary puzzle • X-Sudoku, Jigsaw Sudoku, Mini 6x6 and the big 16x16 • Foxhold: Sudoku as tower defence, our very own game Every type has its own levels, its own best times and its own leaderboard. DIFFICULTY BY TECHNIQUE In classic Sudoku, difficulty follows the techniques a puzzle calls for, not the number of givens: Easy needs singles, Extreme asks for X-Wing and XY-Wing. In the game you see which technique is needed, and after a win, what you solved it with. Every level of every puzzle type can be solved without guessing, with logic alone. DAILY CHALLENGE AND STREAKS One puzzle a day, the same for everyone, with its own daily leaderboard. Solve on consecutive days and your streak grows. Streak shields cover a missed day, so a busy calendar does not undo weeks of work. RANKS, STARS, ACHIEVEMENTS Every solved level counts towards your rank: 19 tiers from Fox Cub to Sagax Immortalis, each with its own fox portrait as a profile picture. Add up to three stars per level and 39 achievements. DUELS AGAINST FRIENDS After a win, challenge someone with a link: they play exactly the same puzzle against your time. No account needed on their side. THOUGHT THROUGH IN DETAIL • A tip that shows you the next technique instead of giving away the digit, plus notes, eraser and undo • Mistakes shown instantly or only at the end, your choice • Digit-first mode for fast entry • Light and dark themes, in ten languages • Puzzles are generated locally, so a dead spot will not stop you You can start playing without an account. With a free account (sign in with Google or Apple), your progress, streak and leaderboard position follow you across devices, including between app and browser. Sudoku Sagax is free, with no ads and no in-app purchases. The den is open. How far will you get?

The Society receives the files that even the Yard cannot close. You are its newest candidate. Every case begins with a floor plan, a handful of people and their statements. Each row and each column contains exactly one figure. The murderer is whoever was alone in a room with the victim. Every statement is true. Every case has a solution, and the cards prove it. Everything you need to find it is right in front of you. No guessing. No clock. No luck. Just deduction. HOW TO PLAY • Read the statements. Each card reveals something about where a person was standing. • Reconstruct the scene. Place the figures, eliminate what is impossible and keep track of what remains open. • Ask the Inspector. If you get stuck, three levels of hints are available – each a little more explicit, always based on your own board. • Make your accusation. The Society does not ask for suspicion. It asks for proof. THE LONDON CASEBOOK 120 files. London, 1928–1940. A séance in Chelsea. A boxing hall after midnight. The Underground at night. A diamond office in Hatton Garden. An incident high above the rooftops of St Paul’s. Across twelve years, guests, suspects and victims return again and again. Some names disappear. Others return. The casebook can be browsed chronologically or by file series. The cases lead from your first admission file to the Master Files. The difficulty grows not through ever larger boards, but through what matters: the depth of the deduction. THE PRACTICE ROOM Members also gain access to the Society’s practice room. There, earlier crime scenes are reconstructed with new casts and recombined again and again. No one dies. Everyone learns. AN ILLUSTRATED WORLD Painterly character portraits, illustrated crime scenes and furnishings, and a casebook inspired by the London of the late 1920s and 1930s. Murder & Method is fully available in English, German, Italian, Spanish and French. MEMBERSHIP The ten files of the admission examination are free. Those who pass may join the Society. A single purchase unlocks the remaining 110 files of the London Casebook. Introductory price until 31 December 2026. The regular price applies thereafter. No ads. No subscription. No account. No tracking. No energy. No coins. Fully playable offline on iPhone and iPad. Made in Düsseldorf by Lindhavn Studio.
