Tangle is an addictive puzzle game of intersecting lines.
The objective of the game is to untangle the mess of lines presented before you. Grey lines are lines that are currently overlapping. To untangle them select a circle and drag it around. When all the lines are untangled you win!
With unlimited levels (although beating level 10 takes some skill) there is a lot of content to go around.
After a little practice challenge your friends online in Multiplayer mode. Or, shoot for the fastest times in the world on the online Leaderboard.
After you've mastered all of that, switch to Expert mode and challenge yourself again.
