Hard Puzzle: Color Lines
You draw lines between matching coloured elements until every pair is connected, but the board fills quickly and paths must not cross. Each level tightens the space and adds more colours, so a single poor choice can leave no route for the last pair. Undo, redo and restart are there when you misstep, and it runs in the browser on desktop, phone or tablet without installation.

About this game
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
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.
