- Codebreaker is a logic game in which a code-breaker tries to break a secret code created by a code-maker. The codemaker, which will be played by the application we’re going to write, creates a secret code of four numbers between 1 and 6.
- The codebreaker gets some number of chances to break the code (depends on chosen difficulty). In each turn, the codebreaker makes a guess of 4 numbers. The codemaker then marks the guess with up to 4 signs - + or - or empty spaces.
- A + indicates an exact match: one of the numbers in the guess is the same as one of the numbers in the secret code and in the same position. For example:
- Secret number - 1234.
- Input number - 6264.
- Number of pluses - 2 (second and fourth position).
- A - indicates a number match: one of the numbers in the guess is the same as one of the numbers in the secret code but in a different position. For example:
- Secret number - 1234
- Input number - 6462
- Number of minuses - 2 (second and fourth position)
- An empty space indicates that there is not a current digit in a secret number.
- If codebreaker inputs the exact number as a secret number - codebreaker wins the game. If all attempts are spent - codebreaker loses.
- Codebreaker also has some number of hints(depends on chosen difficulty). If a user takes a hint - he receives back a separate digit of the secret code.
For development:
- Ruby(v2.7.1)
- Codebreaker gem
- I18n

- Simplecov
Also was used CircleCI for testing.
