## What is Flat?

Flat is a 3D puzzle game that combines minimalist design with profound logic.
The rules are simple: move all the cubes on the board into the black holes to make the board completely flat.

- 50 stages of intellectual challenges
    - As you progress through the stages, new mechanics such as arrow panels and switches will appear.

- Comfortable controls
    - Intuitive swipe controls allow you to immerse yourself in the pleasure of solving puzzles.

- Minimalist aesthetic
    - The stripped-back visuals help sharpen your focus.

Why not clear your mind and aim to complete all the stages?
