Lines is a free Android puzzle game developed by Djon Smit. The objective of the game is to score as many points as possible by forming lines of balls of the same color. The game is easy to play and challenging to master, making it perfect for puzzle game enthusiasts.

To play, simply use your touch screen to move the balls. First, select the ball you want to move, then choose an empty destination square. If the square is already occupied by another ball, that ball will be selected to be moved next. However, you cannot always place the ball where you want to, which adds an extra layer of challenge to the game.

After you move a ball, three more balls will appear on the board, except when you form a line. The more balls in a line, the more points you'll score. With each level, the difficulty increases, and the challenge to clear the board becomes more significant.

Overall, Lines is a fun and challenging puzzle game that will keep you entertained for hours. Download it for free from the Google Play Store and start playing today!
