Stack up the blocks as high as you can! In Stack, players aim to stack blocks as high as possible. The game features simple yet beautiful graphics and offers a competitive element where players can strive for the best score in the world. Players tap to place blocks on top of each other, trying to align them perfectly to build a taller tower. Each misaligned placement reduces the size of the next block, increasing the challenge. The game continues until the blocks become too small to stack.
