We give the first complete combinatorial proof of the fact that the number of domino tilings of the 2n×2n square grid is of the form 2^n(2k + 1)^2, thus settling a question raised by John, Sachs, and Zernitz. The proof lends itself naturally to some interesting generalizations, and leads to a number of new conjectures.
