About

Boundrop

Features
Read full description

Boundrop is a one-screen falling-block puzzle where you combine and clear colorful, jiggly balls. Drop them, fling them, and steer the balls as they bounce off one another to set up chain reactions. Just watching them wobble is oddly satisfying โ€” a great little stress reliever. Every color combo follows the color wheel, so you'll get a feel for mixing and complementary colors as you play. ## HOW TO PLAY - Grab the balls falling from the top and drop them wherever you like. - Same color: balls merge and grow bigger. - Neighboring hues on the color wheel merge into a new color (red + blue = purple). - Complementary colors (red-green, blue-yellow and more) fuse into a BLACK STONE. - Black stones crush the balls beneath them. - Connect 8 or more stones and they all clear at once! - The game ends when the balls pile up and overflow the top. ## FEATURES - Bouncy soft-body physics: every ball springs, squashes and jiggles. - Simple one-finger controls: drag and flick, that's all. - Score & combo system: chain clears within seconds to multiply your score. - Difficulty ramps up the longer you survive. - Three game modes: Endless, 1 Min and 3 Min. - Haptic feedback for every bounce, merge and clear. - Free to play, supported by a single banner ad. No time limit, no stamina, no gacha. Just you, gravity, and a screen full of bouncing jelly.
