[Ruby] Math.. game.. thing

I have no idea what to call this program but it's a game/problem my math teacher used to give us last year. The concept: You need to find a 4 digit number using the numbers 0-9 in the allotted number of tries. If you get one right, you get one more try, get it wrong, you lose one.

It's not my best program and I made it because I got bored in BTT but hey, enjoy!

Code:

actions = (0..9).to_a
@sequence = []
4.times do |key|
	key = actions.sample
	@sequence << key
end
@fails_left = gets.to_i
@correct_a = 0
@correct_r = 0
@a = " "
@b = " "
@c = " "
@d = " "
def sel
	system "cls"
	puts """
    __________________________________
   /   ___     ___     ___     ___    \\
   |  |   |   |   |   |   |   |   |   |
   |  | #{@a} |   | #{@b} |   | #{@c} |   | #{@d} |   |
   |  |___|   |___|   |___|   |___|   |
   \\__________________________________/

Tries left: #{@fails_left}

Enter guess (x x x x):"""
	guess = gets.chomp
	guess = guess.split(" ")
	guess = guess.map(&:to_i)
	@correct_a_prev = @correct_a
	case guess[0]
	when @sequence[0]
		@correct_a += 1
		@a = "#"
	when @sequence[1]
		@correct_r += 1
	when @sequence[2]
		@correct_r += 1
	when @sequence[3]

	end
	if @fails_left == 0
		system "cls"
		puts "you've died. :3"
		sleep
	else
		sel
	end
end
