In Sky High, you have to build a giant tower by stacking up the sliding layers of the stately building. Tap at the right moment to stop the layer from moving to and fro. Try to drop it exactly on top of the previous layer. Any bits that stick out over the edge are lopped off, reducing the size of the misaligned floor. Each subsequent floor of the building will shrink down to the same size. That means that the layers of the building will gradually become smaller and smaller. Keep stacking for as long as you can. You can keep going even with only the slimmest columns of stone left, as long as you don't miss your target altogether. What's your record score?
