Codebreaker is a logic game in which a code-breaker tries to break a secret code created by a code-maker. The code-maker, which will be played by the application we’re going to write, creates a secret code of four numbers between 1 and 6.
The code-breaker then gets some number of chances to break the code. In each turn, the code-breaker makes a guess of four numbers. The code-maker then marks the guess with up to four + and - signs.
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.
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.
Add this line to your application's Gemfile:
gem 'codebreaker'And then execute:
$ bundle
Or install it yourself as:
$ gem install codebreaker
Console interface
require "codebreaker"
Codebreaker::GameInterface.new.run
