Probably something like:

def check_age(age)
  eligible = 18..30
  if age < 18
    print "Sorry, too young."
  elsif eligible === age
    print "Have a great holiday!"
    true  # provide a positive result
  else
    print "Input not understood."
  end
end

print "Please enter your age: "
check_age(gets.chomp.to_i)

# of course I would use a case
# make eligble a constant
# and if required provide the flow control (probably not recursive) in
another function

Good luck
