Light Line

Light Line is a free online puzzle game built around one beautifully simple idea — draw a single continuous line of light that fills every blank space on the grid without missing a single cell. No color matching, no timers, no distractions. Just you, a glowing starting point, and a board that needs to be perfectly illuminated.Developed by Movisoft, Light Line is the kind of puzzle game that feels effortless to start and impossible to put down. Each stage presents a clean, minimalist grid and challenges you to trace a path from the starting point through every empty space — moving up, down, left, and right — until the entire board glows with light. The catch: your line must cover every cell exactly once with no gaps and no dead ends. One wrong turn and you'll need to rethink your entire path.With four difficulty levels — Beginner, Intermediate, Expert, and Master — and hundreds of stages to work through, Light Line scales perfectly whether you're looking for a relaxing brain workout or a genuine mental challenge. Every 20 stages you earn bonus items including hints and hearts to help you through the toughest puzzles. Satisfying, meditative, and endlessly replayable. Play Light Line free in your browser on desktop or mobile, right here on VPlay — no download needed.
