About

Close

Code Breaker is derived from a game called Bulls and Cows of unknown origin. It's game principle is public domain. There are commercial versions of Bulls and Cows from other parties using different names or trademarks being published and being available as well. Code Breaker is MIT licensed and just uses the public domain principle of the game Bulls and Cows. It comes bundled with third party software libraries using free software licensing.

Rules

The rules of Code Breaker are as follows.

  • Iteratively a guess is stated to be compared towards a secret four digit code with six possible values per digit (letters from a to f).
  • Objective is to match the secret code perfectly.
  • On each guess a result indicates the amount of perfect matches and imperfect matches represented as numerical values.
    • Perfect matches indicate that a digit is included in the secret and is placed at correct position within the guess.
    • Imperfect matches indicate that a digit is included in the secret but the position is still incorrect.
  • Thus the secret code is found if four perfect matches and no imperfect match are indicated on a check.
  • Digit values may occur multiple times. No digit of the guess will count multiple times in the indicated result. Indicating perfect matches over imperfect ones is prioritized. Previous check results are kept visible in a log to use for analysis.
