Stack Up

Stack Up gives a familiar block puzzle an unexpected twist: the shapes rise up from the bottom of the screen instead of falling from above. Each shape is made of four squares, and you can rotate it and shift it sideways as it climbs.

The goal is the same as in classic block games. You need to fit shapes together so they form complete rows with no gaps, and each finished row is cleared and adds to your score. If you leave holes, the board fills up quickly. Because the direction is reversed, the game takes a few minutes to get used to, and then it becomes very absorbing.
