### How to Play & Core Mechanics
Your goal is simple: fill the entire 3D structure by drawing one continuous path through all the empty cubes. Tap and drag your finger (or mouse) to connect adjacent cubes. The path cannot cross itself, and you must cover every single cube in the puzzle. Each **level** presents a new captivating 3D shape, from simple lattices to complex geometric figures, steadily testing your logic.

### Brain Training Benefits
This isn't just a game; it's a workout for your mind. **3D Fill** sharpens your:

### Essential Tips for Success
* **Start from the Edges:** Begin your path from a corner or an outer cube. It’s easier to work your way inward.

* **Identify Chokepoints:** Look for cubes that have only one or two possible connections. These are critical and must be connected correctly early on.
* **Don’t Be Afraid to Restart:** If you get stuck, hit reset. A fresh perspective often reveals the solution.
* **Think in Sections:** Break down the complex shape into smaller, manageable clusters in your mind.
