Drag nodes to untangle
Drag the nodes so that none of the connecting lines cross.
Each level shows a graph of nodes (dots) connected by lines. The lines start out crossed up — your job is to rearrange the nodes so no two lines cross.
Drag any node to a new position. The lines follow. The Crossings counter at the top shows how many pairs of lines still cross — when it reads 0 as you lift your finger, the level is solved and the next one begins. Lines lying on top of each other, or a line passing through a node, count as crossings too.
Every puzzle is guaranteed solvable: there is always a layout with zero crossings.
The graphs grow until level 10 (12 nodes and up to 17 lines); after that every level is that size. You have 2 minutes.
Goal: most levels cleared in 2 minutes.
The fastest way to zero crossings is to spread the nodes out first — drag everything apart so the tangle of lines becomes legible, because crossings are far easier to spot and fix on a sparse layout than on a crowded knot. Give yourself room before you start reasoning about which line goes where.
Look for the node with the most lines coming off it and place it where its connections fan out cleanly, since a single busy hub causes most of the mess. A reliable trick is to drag a heavily connected node toward the edge so its lines splay outward instead of crossing through the middle. Many small graphs settle neatly into a rough circle or convex shape, so when you are stuck, try arranging the outer nodes around a ring and tucking the rest inside, then nudge whatever still crosses.
