Fill Line is an online logic puzzle game where you complete each shape by drawing one continuous path. Your goal is to fill every available line without crossing or revisiting a section you have already completed. The first levels introduce the basic rules, while later puzzles feature more complicated layouts that require careful observation and route planning.
How to Play Fill Line
Click or touch the starting point, then drag along the empty paths. Continue drawing until every line in the puzzle has been filled. Each section should be completed only once, and your path cannot cross itself or return through a line that has already been used.
Before making your first move, study the complete shape. Look for narrow sections, corners and routes with limited access. Choosing the wrong direction early in the puzzle may block part of the remaining path, so try to think several moves ahead.

Tips for Solving Fill Line Puzzles
Study the Complete Shape
Take a moment to inspect the entire layout before drawing. Narrow paths, corners and isolated sections can provide useful clues about the order in which the route should be completed.
Complete Restricted Areas Carefully
Sections with limited access are often more difficult than large open areas. Consider how you will enter and leave these parts of the puzzle before closing nearby routes.
Do Not Close the Route Too Early
Be careful when drawing around the outside of the shape. Completing a loop or surrounding an empty section too soon may block the only remaining way to reach it.
Think Several Moves Ahead
A move may appear correct at first but still lead to a blocked path later. Before continuing, consider where your current direction will leave you and whether all remaining lines will still be accessible.
Review the Route After a Mistake
When a route does not work, restart the level and reconsider the direction of your earlier moves. Remember where the remaining path became blocked and use that information to plan a better solution.
Why Play Fill Line?
Fill Line combines straightforward controls with puzzles that gradually become more demanding. The game does not depend on speed, quick reactions or complicated commands. Success comes from studying the layout, selecting the correct route and keeping every unfinished section accessible.
This makes Fill Line a suitable choice for players who enjoy line puzzles, path-finding games, drawing challenges and logic-based gameplay. The short levels are easy to begin, while the more complex shapes may require several attempts to solve.
