An "Unholey" Magic Square is a take off of "Unholey Primes": primes which only use digits that do not have "holes" in them: 1, 2, 3, 5, and 7. In this one I used only the digits 1, 2, and 3 because there are 81 ways to write 4 digit numbers using only 3 different digits, and as I mentioned before a 9 x 9 Magic Square has 81 block to fill.
