Murder & Method
Read full descriptionHide full description
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.

Rings turn one notch per tap. A dot can hop to the next ring only at the exact moment two rings kiss. Land every dot in its socket in the fewest moves. A logic puzzle with one exact rule, no timer and no luck. NEW IN 2.0: ENDLESS A fresh board every time, made on your phone and proved by the solver before you see it. Six difficulties, drawn at random after an easy start, from gentler than Orbit 1 to as tough as Orbit 6. Solve at par to grow your chain. No timer, no lives, no end. ONE RULE, EXACT Tap anywhere and every ring clicks round by its own spin: +1, −1, +2, or not at all. Tap a dot while it sits at a kiss and it arcs across to the touching ring. That is the whole game. Nothing is random inside a level and nothing is timed, so every board is a small piece of clockwork you can read before you touch it. THE CLICK OF GEARS MESHING The feeling you chase is the socket swinging into the kiss as the dot arrives. Every tick, hop and dock has its own sound, haptic and light: the notch marks blink in sequence, the hop leaves a luminous trail, the socket blooms, and a solved level ends on one calm chord. 120 LEVELS IN SIX ORBITS Every level was generated and proved by a solver, so par is the true minimum and a level is never unsolvable, only over par. Every orbit is free to reach: earn 40 stars in one and the next opens. Each adds one twist: • Kiss – two rings, one dot, one socket. Learn the hop. • Wall – a stop bar rides the ring and refuses a landing. • Flip – a marked notch sends its ring the other way. • Three – a third dot, and three colors to route at once. • Still – rings that do not turn, and mixed spins. • Tangent – everything, on twelve-notch rings. Three stars means par. Undo is free and unlimited, restart is free, and one hint per level shows the solver’s next move. ONE DAILY, ONE STREAK A new brain teaser every day, built on your phone from the date, the same for everyone. Par is shown before you start. Solve it and your streak grows; share the result as text, not a screenshot. Reminders are optional, up to three a day, and stop once the day’s puzzle is solved. MADE TO BE READ Every dot and socket carries a shape as well as a color, so no rule depends on color alone. Reduce Motion turns every pulse and burst into a fade. VoiceOver and Dynamic Type are supported throughout. Sessions are two to five minutes, one-handed, and every move is saved, so you can put the phone down mid-level and pick up exactly where you were. WHAT’S INCLUDED • Game Center: leaderboards for total stars and best streak, seven achievements. • iCloud: your progress follows you to a new phone. • No account, no in-app currency, no lives, no timers. FREE TO PLAY, ONE UNLOCK TANGENT is free to play, with ads: a banner on the menu screens, never on the board, and now and then a short ad between puzzles. TANGENT Full Game ($4.99, once, no subscription) removes every ad, opens all six orbits at once, and adds the daily archive of the past 30 days and Skip board in Endless. Without it, you can watch an ad to skip an Endless board. Restore Purchases and offer-code redemption are on the Unlock screen and in Settings.
