Any ideas for compacting this code down?

Question

I've done this as an exercise in loops. Can anyone suggest ways of compacting it down?

test2.rb:

def main
pick
go
again
end

test.rb
require 'colorize'

def again
if $i == $p
puts msg(2) # Would you like to go again?
answer = gets.downcase.chomp.to_s
if answer == "yes"
main # Go back to the beginning
else
msg(4) # Are you sure?
confirm = gets.downcase.chomp.to_s
case confirm
when "yes"
msg(3) # Ok then, thanks for playing
when "no"
main # Go again
else
msg(5) # Msg for unrecognisable input
end
end
else
puts msg(3) # Ok then, thanks for playing
end
end

def pick
msg(6)
$p = gets.chomp.to_i
end

def go
$i = 0
while $i < $p
msg(1)
input
options
sum
$i += 1
#count
end
end

def sum
a = $p - $i - 1
if a >= 0
puts "You have #{a} goes left..."
else
again
end
end

def input
@b = gets.chomp.to_i
end

def options
if @b <= $p
@b
elsif @b > $p
puts "#{@b}".red + " is too large!".white
puts "Try again!"
go
else
puts "Wrong! Try again"
go
end
end

def msg(n)
case n
when 1
puts "Choose a number between 1 and #{$p}".red
when 2
puts "Would you like to go again?"
when 3
puts "OK then, thanks for playing!"
when 4
puts "Are you sure? Yes/No?"
when 5
puts "I really don't know what you want from me. I'll assume you don't want to play. Goodbye!"
when 6
puts "Pick a number... ".blue
end
end

def count
puts "i = #{$i}"
end

Answer 1

I'm not very good in Ruby, but I can suggest one thing; please use the Code Playground to type and run your code 😉 Just a reminder, it makes it easier for others to help you 👍

Answer 2

In case you don't know how to write and run your codes in the code playground, to create a new code press the little plus icon in the code section (On your profile or the trending section) and choose your language ☺

Answer 3

I know about that, I’m interested in what OTHER people ARE able to do with the code.
