Classic Lines is a free Android puzzle game developed by SharLines Corp. that is sure to entertain both children and adults alike. The objective of the game is to form horizontal, vertical, or diagonal lines of at least five balls of the same color by moving them around the board. When a line is formed, the balls in that line disappear, and the player earns points. If a line is not formed, three new balls are added to the board. The game continues until the board is full, and the goal is to make optimal moves and earn the highest score possible.

The game offers four difficulty levels: "Baby," "Beginner," "Professional," and "Expert." The "Baby" level is specifically designed for young children, while the "Beginner" level is perfect for new players. The "Professional" level offers a more serious challenge for experienced players, and the "Expert" level is a real brainstorm for advanced players. Additionally, there is a custom difficulty level where players can manually adjust the board dimension, color count, and line length.

Classic Lines is designed to work on both phones and tablets and is best played in portrait screen orientation. With its simple yet addictive gameplay and various difficulty levels, Classic Lines is a great choice for anyone looking for a fun and challenging puzzle game.
