Two six sided dice are marked with 12 different integers, so that any number from 1 to 36 can be derived when both dice are thrown and the showing face-up values are added.
What is the lowest possible value of the highest number on one of the dice faces?

Since we've been given the 21 hint:

16,17,18,19,20,21

-15, -9, -3, 3, 9, 15
