I'm trying to build the classic MasterMind game in Ruby but I can't seem to put it all together.

Question

class Game
    COLORS = %w{red yellow green blue}.sample(4)
    puts COLORS
    attr_accessor :guess
    def initialize
    puts "Started a game."
    @answer = []
    @guess = guess
    end

    def rules
        10.times do |x| player_guess

            if @answer == COLORS
            puts "You Win!"
            else
            puts "try again!"
            end
        end

    def player_answer          #Here we put the players answer into the @answer array.
        @answer.push(guess)
        puts @answer
        end
    end

    def player_guess
        puts "Go ahead and choose 4 colors in any order from red, yellow, green, and blue. Then hit enter."
        guess = gets.chomp
    end


end

game = Game.new
game.rules
```Ruby

#Now I know this doesn't follow all the rules the original game MasterMind but I was hoping there is someone out there who is familiar enough with it to help me get this small example working. If anyone could help you will have my eternal gratitude.

The problem is in your loop, It is checking to see if the answer array is equal to the colours array. But the answer array is always empty because it never gets any of the guesses added to it.

I got it to work with the code below, You will have to enter the exact sequence of colours in to get it to evaluate to win in its current form.

I made a mastermind game in ruby a few weeks ago, You can have a look at here if you like: https://github.com/KevinMulhern/ruby_oop/blob/master/mastermind.rb

class Game
    COLORS = %w{red yellow green blue}.sample(4)
    puts COLORS
    attr_accessor :guess
    def initialize
    puts "Started a game."
    @guess = []
    end

    def rules
        10.times do |x| 
            @guess.push(player_guess)
            if @guess == COLORS
                puts "you win"
            else
            puts "try again!"
            end
        end

    def player_guess
        puts "Go ahead and choose 4 colors in any order from red, yellow, green, and blue. Then hit enter."
        guess = gets.chomp
    end


end

game = Game.new
game.rules

Wow thanks! This was exactly what I was hoping for. I looked over your project awhile and was very impressed! there are a lot of MasterMind examples out there but none as thorough as yours. Honestly your project looked really good and I noticed you had some methods and pieces I have yet to learn. When you were writing your code what did you use for assistance or as a reference?
