iPhone

There has been a murder. You have a grid, one person per row and per column, and a card for each suspect carrying one true clue. The victim was alone with the murderer: work out where everyone stood, and a single person will be left in the victim's room. That is your culprit. EVERY CASE IS SOLVED BY REASONING There is never anything to guess. Each case has exactly one solution and you reach it by pure deduction. Every single case was machine-verified before shipping. If you are stuck it is not bad luck: there is still something to read. 735 CASES, SEVEN SETTINGS An old harbour, an orbital station, a castle, a Christmas village, a Wild West town, an Egyptian pyramid and a grand hotel, each with 100 cases plus 5 bonus ones. Grids run from 6×6 to 16×16, ordered by difficulty, and you play them in any order you like. A NEW CHALLENGE EVERY DAY The same case for everyone, changing at midnight, with a daily leaderboard of times. HINTS THAT EXPLAIN WHY A hint does not just place a person: it tells you which clue proves it and which steps lead there. It teaches you to see, instead of skipping the case. FREE TO START, ONE PURCHASE FOR EVERYTHING The tutorial, the daily challenge and five cases in every setting, from beginner to expert level, are free. A single one-time purchase unlocks every case and the archive of past daily challenges, forever. No subscription. Or open cases one at a time by watching an optional video. WORKS OFFLINE The cases ship inside the app. Play on a plane, on the underground, in the middle of nowhere. Sign in with Apple or Google if you want your progress on another device: it is optional, and the game is complete without an account. ALSO • Pencil marks on the grid, exclusions, undo • A timer that pauses when you leave a case • Trophies that tell you how you earned them • Sixteen suspects, redrawn for every setting LANGUAGES The game itself (clues, rules and menus) is available in English, Italian, German, Spanish, French, Portuguese, Dutch, Norwegian and Romanian. SUSoku is inspired by Murdoku-style murder logic puzzles. It is an independent game with original maps, clues and artwork, and it is not affiliated with any book or publisher.
