Fill The Lines

About Fill The Lines: A Stress-Free Line-Drawing Puzzle

Fill The Lines is a thinking game built around one satisfying goal: draw lines to complete a given puzzle shape without leaving any blank spots. The puzzle presents an empty shape, and a set of colorful blocks sits ready to be placed. No timers count down, and there is no losing condition — just hundreds of unique levels to work through at whatever pace suits you, on a computer or mobile device.

Several scenes show a solid blue-green background surrounding a centered gray grid of small squares. The colorful pieces themselves appear in orange, pink, purple, yellow, light blue, and green, each containing circular nodes connected by paths.

How to Play Fill The Lines: Fill Every Blank Spot

Each level opens with a puzzle shape made up of empty blank spots. Colorful blocks — each built from line segments or shapes — are available to place into that shape. The objective is to fit every block so that all blank spots are covered and no gaps remain.

Drag a block into position using touch or mouse, then keep placing pieces until the shape is completely filled. Completing a level advances you to the next one. Because there is no time limit and no way to lose, every attempt is simply a step toward finishing the puzzle.

Controls

• Finger drag (touch screen): Pick up and place a colorful block into the puzzle shape
• Left mouse button click and drag: Pick up and place a colorful block into the puzzle shape
