Dive into the underwater world of Unblock It 3D: Atlantis and test your logic with endless brain-teasing puzzles! Rotate the puzzle cube to reveal which blocks you can slide away. Discover a vast collection of levels inspired by the lost city of Atlantis, featuring stone tiles textured like coral, shimmering pearl finishes, and sea flora woven through ancient ruins. Unlock new cube styles, explore vibrant oceanic themes, and keep your mind sharp as the puzzles grow more complex.

Clear the entire 3D puzzle by sliding blocks in the direction shown by their arrows. If a block isn’t blocked by another, you can swipe it away.
