DuBlox is a great puzzle game from HoodaMath. At first glance this game looks easy—all you have to do is move some blocks around a board, there’s no timer and nothing trying to kill you. But you’ll quickly find that flipping these little blocks in just the right sequence is pretty challenging. Most casual games don’t require you to think in 3D, but this one will. As you move through the levels the game gets more complex, adding obstacles and special buttons/squares.
