Blockstacker is an easy-to-learn, but challenging game where you slide rows on the board to match stacks of colored blocks to gain points. Every time you reach a new level, you get a chance to gain extra points by matching a lock and key. Watch out for the evil Magno Skulls, as they will connect with each other, and make rows move together. Use Hearts, Bombs and Orbs to your advantage, and keep the board clear.
