Just for fun, here's a little rewrite:

number = 5 + rand(65)

print "Try to guess the Magic NuMbeR between 5 and 69: "

diff = { false => "bigger", true => "smaller" }

loop do
   user_try = gets.to_i
   break if user_try == number
   puts "The NuMbeR is #{diff[user_try > number]} than #{user_try}!"
   print "Try again: "
end

puts "Congratulations! You found the Magic NuMbeR!" 
puts "The NuMbeR is #{number}."
