Hey, ruby-quiz is back?!
This is how I would have done it... One loop, break-out once you got the
number. Maybe it helps.. Cheers, Martin


magic = rand(101).to_i
puts "Guess the magic number!"

loop do
  print "Choose 0-100> "
  n = gets.to_i
  if !(0..100).include?(n)
    puts "0-100!" 
    next
  end
  puts "Higher!" if n<magic
  puts "Lower!" if n>magic
  break if n==magic
end

puts "You won: #{magic} is the number!"
