About

Unite Drop

Features
Read full description

Unite Drop is a simple yet deep 3D falling puzzle game where you drop colorful balls and merge them together. It's a merge-drop style game. * How to Play Just tap the screen to drop balls. When balls of the same color touch, they merge and evolve into larger balls. Keep creating bigger and bigger balls. When you merge the largest purple balls, they disappear. * Game Features - Simple controls: Anyone can enjoy immediately with just a tap - Position guessing: It's 3D but you can't change the viewpoint. Guess the spatial relationships inside the box from how the balls cluster together - Combo system: Chance for high scores with consecutive merges - Ranking feature: Compete for scores with players nationwide - Pleasant visuals: Gentle pastel color design How high can you score in the limited space? Why not test your skills? * FAQ Q. Is there no online ranking? A. It's planned for future updates. Q. Is there no sound? A. Sound effects will be added in the future. BGM is undecided. Q. A ball disappeared even though it wasn't the maximum size A. When 3 or more balls of the same color stick together at exactly the same time, they may disappear. It's a bug, but we're keeping it because it's interesting.
