Untangle the Lines

Untangle the Lines turns a messy tangle of nodes and connectors into a calming mental workout. The objective is straightforward: shift the points around the canvas until every line runs cleanly without crossing another. Each level presents a fresh web of connections, and your only tools are your mouse or finger and a bit of spatial reasoning. As you progress, the configurations grow denser, demanding more careful planning and a steady hand. This puzzle is designed for quick bursts of play or longer, more contemplative sessions. The controls are simple—just drag any point to a new spot—but the satisfaction comes from watching the chaos resolve into a neat, orderly pattern. There’s no timer and no pressure, so you can experiment freely, undo mistakes, and find your own pace. Whether you’re killing a few minutes or diving into a series of levels, it’s a gentle test of logic that keeps you coming back for one more puzzle.

What is Untangle the Lines

If you enjoy clearing up visual clutter, this puzzle will hook you right away. Drag the nodes, untangle the mess, and enjoy a moment of quiet satisfaction.

How to Play

Click or tap a node and drag it to a new position on the board. Your goal is to move the nodes so that no two lines cross each other.

Tips for Playing

Start by moving the nodes with the most connections first, as they often create the most crossings.
Try to form a simple outer polygon with the most connected nodes, then place the others inside.
Keep an eye on the edges—lines that cross near the border are often easier to untangle than those in the middle.
If you get stuck, don't hesitate to undo a few moves and try a different approach.
Sometimes a small adjustment of one node can resolve multiple crossings at once.

Frequently Asked Questions

How do I know when a level is solved?

A level is complete when no lines are crossing each other on the board. The game will typically show a success message or proceed to the next level automatically.

Can I restart a level if I make a mess?

Yes, there is usually a reset or restart button. You can also undo individual moves to step back gradually.

Is there a time limit?

No, the game is relaxed and untimed. You can take as long as you need to figure out each puzzle.

Does the game work on mobile devices?

Absolutely. All you need is a touch screen, and you can drag nodes with your finger just as easily as with a mouse.

What happens when I finish a level?

You'll advance to the next, more challenging level. Each new stage introduces a more complex web of lines to untangle.

Are there any hints or help features?

While the game focuses on self-solving, you can use the undo and restart options to guide your thinking. There are no built-in hints to keep the challenge pure.
