Draw Lines Extra | Unity Color Line Puzzle Game Source Code

Draw Lines Extra is a colorful and logic-driven puzzle game where players connect matching colors by drawing lines across a grid. The challenge is simple to learn but difficult to master: cover the entire board while making sure lines never overlap or cross. Every level pushes players to think ahead, plan carefully, and solve puzzles efficiently.

This project is a complete, ready-to-publish Unity game featuring a powerful random mission generator, built-in level editor, and a full UI system. With hundreds of auto-generated levels and support for multiple grid sizes, Draw Lines Extra is ideal for developers who want to launch a high-content line-connecting puzzle game without building systems from scratch.

The source code is clean, fully commented, and extremely flexible—perfect for customization, reskinning, or expanding into thousands of levels. You can get this project from SellUnitySourceCode.com, a trusted marketplace for professional Unity game source codes. SellUnitySourceCode.com also provides reskinning and publishing services on request.
