Screwdom 3D

Screwdom 3D, developed by iKame Games - Zego Studio, is a 3D mechanical physics puzzle game that has become a breakout title in the spatial sorting genre. Generating over 23 million downloads, achieving a 4.56 rating across 320,000 reviews, and ranking among Google Play's top casual puzzle titles, the game expands upon traditional 2D screw-sorting puzzles by moving them into three dimensions. Instead of flat boards, players encounter layered 3D objects—such as toy ducks, model houses, and geometric figures—fastened together by color-coded screws, pins, and interlocking plates.

The core mechanics combine spatial problem-solving with sorting systems. The screen displays target screw boxes that accept specific colors (e.g., three red screws or three blue screws). Players tap screws embedded in the 3D model to extract them. If a screw's color matches an active open box, it sorts into place immediately. If no corresponding box is open, the extracted screw must be placed into a limited staging hole buffer. If all buffer holes fill with mismatched screws, no further pins can be removed, resulting in a failed attempt.

Physical simulation plays an active role in puzzle progression. Loosening all fastening pins from an acrylic or metal plate causes it to drop off the model via gravity, uncovering deeper structural layers and additional screws. Players must mentally plan their sequence of moves: extracting a screw simply to free up space can backfire if it fills the last staging hole, while removing a specific support pin might clear an entire plate and reveal required colors. The presentation emphasizes ASMR satisfaction, featuring distinct metallic clicks, subtle vibrations, and clean visual details. Monetization blends interstitial ads, rewarded video options to unlock extra buffer holes or undo moves, and in-app purchases for tools like drills and clearing hammers.
