A web of glowing strings is knotted over itself. Drag the orbs apart, watch the red crossings drain to zero, and leave behind one clean, untangled constellation.
About Untangle
Untangle hands you a snarl of neon strings on a deep-space board and one simple demand: no line may cross another. Every red segment is tangled with something; drag an orb and the strings follow it live, flicking from red to cyan the instant they come clear. The crossing counter in the corner ticks down as you work, so you always know exactly how much knot is left.
The early boards come apart in a few tugs. Later ones pack nearly fifty orbs into a lattice where fixing one crossing quietly creates two more on the far side. That is where the real game lives: you stop dragging on instinct, spot the outer ring hiding inside the mess, and peel the graph open from the edges instead of yanking at its middle. Pulling one stubborn orb across the board and watching thirty crossings collapse at once is the moment that keeps you loading the next knot.
All sixty puzzles are guaranteed solvable, your best time per level is saved, and undo forgives any tug you regret. Good for a two-minute breather or a long, stubborn evening.
Where Untangle comes from
This puzzle is Planarity, written in Flash by John Tantalo at Case Western Reserve University in 2005 from a concept by Mary Radcliffe of Western Michigan University. Every level is a planar graph drawn with its vertices on a circle so that the edges cross, and a theorem by Istvan Fary guarantees such a graph can always be redrawn with straight edges and no crossings, so every puzzle is solvable. The game's viral spread earned Tantalo a place among Cleveland's 'most interesting people' of 2006; this version is 360 PlayZone's own take on the classic. Source.

How to play Untangle
Grab any orb and drag it somewhere new; the strings attached to it move with you. Edges that cross another edge glow red, clean ones glow cyan, and the counter shows how many crossings remain. Rearrange the orbs until the counter hits zero to clear the level and unlock the next. Finish quickly to earn three stars for that knot.
Controls
Desktop: drag orbs with the mouse, Z undoes, R resets, M mutes, Esc opens level select. Touch: drag orbs with a finger and use the on-screen buttons for undo, reset, levels, and sound.
Tips & tricks
- Start from the rim: park the obviously-outer orbs in a wide circle first, then untangle the middle inside that frame.
- Orbs with only two strings are cheap to relocate; sling them far out of the way and deal with them last.
- If a knot will not loosen, one orb usually belongs on the opposite side of the board entirely; carry it across and see what falls clean.
- Stretching helps: spreading everything toward the edges makes the remaining crossings easy to read before you commit to fixes.
