Code-breaking as a spy dossier. One clue lies. 480 cases, daily, duel. $2.99 once. No ads. Mind Cipher is a Mastermind-style code-breaking game — Bulls and Cows, Hit and Blow, played with colors — filed as a spy dossier. Crack the hidden color code from ink marks: a filled dot is exact, a ring is the right color in the wrong slot, a dash is not in the code. The marks never rely on color, and an optional Shape Marks setting gives every peg its own outline. Then open the Lie file. Exactly one report in the round is fake. The rest are true. Cross-check the reports, find the contradiction, and crack the code anyway. Classic cases teach the real marks: 240 cases from beginner to master. Lie cases run a matching 240 where one clue always lies. Today's Case is a new puzzle every day, with Top Secret lie days and a home-screen widget. Duel Mode is pass-and-play: one sets the code, the other breaks it. Notes sit on the board so you can mark eliminated and confirmed colors. Informants (hints) are recruited by closing cases. Every closed case ends with a stamped report you can share. No ads. No account. Free to start: Today's Case, Duel, Classic 1–40, and Lie 1–80. Pro is a one-time $2.99 unlock for the rest of both files, Free Play, and the custom editor. The app follows your language, or you can set it in Settings: English, 简体中文, 繁體中文, 日本語, 한국어, Español, العربية, Deutsch, Français, עברית, Português, Türkçe.

Mind Cipher is now a spy dossier. Paper, typewriter type, rubber stamps and a filing cabinet of case files replace the old look, with a new app icon to match. Feedback marks are pure ink — dot, ring, dash — so they never rely on color, and a Shape Marks setting gives every peg its own outline for color-blind players. Every closed case ends with a stamped report you can share. Today's Case now climbs through the week — 4 pegs and 6 colors on Monday, 5 pegs and 8 colors by Sunday — with Top Secret lie days and a home-screen widget. Two themes: Dossier and Night Desk. Dynamic Type and right-to-left layouts are supported throughout.
