Mind Cipher
Read full descriptionHide full description
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.

Verdict
The clearest difference is in-app purchases: Bigger Math at none against Mind Cipher's 4. Bigger Math also leads on device support (3 vs 1) and iOS requirement (12.2 vs 17.0). Mind Cipher's advantage is update cadence (every 10 days vs every 6 months). On price and ads there is nothing between them.
