Light Line

Light Line challenges you to fill every empty space with one smooth touch, using careful paths and smart moves to clear increasingly tricky stages.

Light Line turns one simple idea into a surprisingly tricky puzzle: cover the entire board without lifting your finger. Each stage contains connected blocks with one colored starting point. From there, your light line must travel through the available spaces until nothing remains empty.

ONE TOUCH FROM START TO FINISH

The colored block marks the beginning of your route. Touch it, then slide continuously across the connected blocks to spread the light through the puzzle.

The key rule is simple: your finger stays on the screen while the line moves. Every empty space needs to be filled, so the route has to be planned with the whole shape in mind rather than just the next few blocks.

Some layouts may look almost solved until one awkward corner reveals that the chosen path was wrong.

Gameplay Built Around the Perfect Route

Light Line does not rely on complicated controls or fast reactions. The real challenge comes from spotting how the blocks connect and deciding where the line should travel.

• Starting point: The colored block shows where the route begins.
• Continuous movement: Slide across the blocks without lifting your finger.
• Complete coverage: Fill all available spaces to finish the stage.
• Increasing difficulty: Later levels introduce more challenging shapes that require greater attention and route planning.

Hints When the Path Gets Tricky

Light Line provides hints to help you continue. Free hints are available, while additional hints can be accessed by watching an advertisement. The hint system keeps tougher puzzles from becoming complete roadblocks, while players who prefer solving everything themselves can simply keep experimenting with different routes.

Simple Controls More Difficult Puzzles

Light Line keeps the interface minimal so the shape itself remains the focus. No complicated button combinations are needed. Just find the colored starting block, keep your finger down, and guide the light through the entire layout.
