PatternCrack: crack the colour code

PatternCrack is a logic game where you have to crack a secret colour code. After each guess you get feedback, black pegs mark a correct colour in the correct position, white pegs mark a correct colour in the wrong position.

The principle is the same: you guess a colour combination, get feedback after every attempt about correct colours and correct positions, and reason your way to the solution. Anyone who knows the board-game classic with the coloured pegs will feel at home straight away. Unlike on the board, you set the code length, the number of colours and the number of attempts yourself, and there is a daily challenge with Game Center leaderboards on top.

Mastermind is a registered trademark of its respective owner. The name appears here only so you can place the game principle. PatternCrack is an independent game with no connection to that company.

You can configure difficulty individually, code length (3–6 pegs), number of colours (4–8), number of guesses (6–15 or unlimited), and whether duplicates are allowed.

Yes, in custom games you can use one hint per game, which reveals one colour of the secret code. It does cost you a guess, though. The Daily Challenge has no hints, so every player faces the exact same puzzle.

Every day, all players worldwide get the same secret code, with only one guess. Can you keep a winning streak going day after day? Via Game Center you can compare yourself to friends and the global leaderboard.

Yes, after the Daily Challenge you can share a spoiler-free result summary. It shows your run as a progress bar together with your current streak, without giving away the secret code, perfect for comparing with friends.

Yes, the “Daily Challenge” widget is available for both the Home Screen and the Lock Screen. It shows at a glance whether you have already played today's challenge and how long your current streak is. Tapping it opens the app.

PatternCrack supports comprehensive iOS accessibility:

• VoiceOver: every peg, feedback and guess row is spoken
• Voice Control: play purely by voice
• Dynamic Type: adapts to the iOS „Larger Text" setting
• Symbols on pegs: each colour also gets a unique symbol (star, triangle, square …) for users with colour-vision differences. Enable it in App Settings → Accessibility
• Reduce Motion: respects the iOS setting and skips animations like confetti
• Dark Mode: follows the system appearance automatically

Yes, all games are automatically saved to your game history. Results sync across devices via iCloud.

PatternCrack is available in 9 languages, German, English, Spanish, French, Japanese, Arabic, Simplified Chinese, Brazilian Portuguese and Russian. The app follows your device's system language automatically.
