Untangle
Move the dots. Clear every crossing. Match the minimum.
How to play Untangle
Every dot is joined to other dots by straight lines. Drag one dot and all of its connected lines follow. Your goal is to arrange the graph so that no lines cross and no dots overlap. Red lines still cross; when the whole graph turns green, the puzzle is solved.
One completed drag counts as one move, no matter how far the dot travels. The Par number is the fewest moves possible for that puzzle. You can solve in more moves, then restart and use what you learned to find the perfect route.
How to solve in fewer moves
Follow clusters of red lines
A dot attached to several crossed lines is usually more valuable than a dot attached to only one. Moving that single junction can clear several crossings at once.
Make space before making a shape
You do not have to recreate a particular drawing. Move crowded dots toward open parts of the board, keep connected neighbors near one another, and let the graph settle into any clean layout.
Plan the whole drag
A move is counted when you release a dot, so you can test positions while holding it. Watch the live crossing counter and release only when the new position clears the most red lines.
Difficulty levels and custom graphs
Easy puzzles use 6 dots and have a minimum of 1 move. Medium uses 10 dots with a 3-move par, Hard uses 12 dots and needs at least 4, while Expert expands to 15 dots with a 5-move par. All 64 puzzles are checked during the site build: the answer layout has no crossings, and the published par cannot be beaten.
The Custom option generates graphs of any size from 6 up to 30 dots on your own device, with the same proven-minimum par. Every puzzle shows a short code under the board - save it or copy its link to rebuild that exact graph any time.
Frequently asked questions
What is the goal of Untangle?
Move the dots until no two lines cross. The shape does not need to match a hidden picture; any crossing-free arrangement wins.
What counts as a move?
Each completed drag of one dot counts as one move. You can drag a dot as far as you like before releasing it.
Is the par score really the minimum?
Yes. Every included puzzle is generated from a planar graph and checked offline. Its starting crossings prove that at least the par number of dots must move, and a solution in exactly that many moves is verified.
Do I have to place dots in exact positions?
No. There is no hidden target layout. You win as soon as every line is clear and no two dots overlap.
Can I replay a specific puzzle or play bigger graphs?
Yes. Every puzzle shows a short code under the board - enter it later to rebuild that exact graph. The Custom option generates graphs from 6 up to 30 dots on your device.
