Cube Merge Lab is a fun and brain-teasing 3D puzzle game where blocks fall automatically in different shapes. Swipe left or right to rotate the view, observe carefully, and let cubes drop into the perfect position. Match and form 4 tiles on the same plane to score points and build higher stacks. The faster you rotate and the smarter you place, the higher your score. Easy to play, hard to master, Cube Merge Lab challenges your spatial thinking, timing, and strategy in a colorful lab environment.
