Hard Puzzle: Color Lines

About Hard Puzzle: Color Lines

Hard Puzzle: Color Lines challenges you to connect pairs of matching colors by drawing lines across a grid without overlapping paths. Each level requires careful planning to fill the board completely, as the available space becomes tighter and the number of colors increases. The rules are simple to understand, making it easy to start, but the puzzles grow steadily more complex, testing your logical thinking and spatial awareness. With the option to undo moves or restart if you get stuck, this brain training game offers a satisfying balance of relaxation and challenge for players who enjoy color-based logic puzzles.

How to Play

On each level, connect pairs of the same color with lines and fill the board neatly without blocking other colors.
• Tap a colored element and draw a line to its matching pair.
• Lines must not cross, and you usually can’t leave extra gaps.
• If a move doesn’t work out, use undo/redo or restart the level.
• Your goal is to connect all color pairs and complete the level.
