What is Hard Puzzle: Color Lines?

Hard Puzzle: Color Lines is a logic game where you connect matching colored elements and draw paths across the board, planning every move. The levels gradually become harder: more colors appear, there’s less free space, and more situations where it’s easy to make a mistake. The game is great for relaxing while still giving your brain a workout — short levels, clear rules, and a real challenge closer to the final stages.

How to play Hard Puzzle: Color Lines

On each level, connect pairs of the same color with lines and fill the board neatly without blocking other colors.

• 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.
