Tangle

If you're on the hunt for an addictive and challenging puzzle game, Tangle might just be it. This game revolves around intersecting lines that need to be untangled - but that's easier said than done. The grey lines signify what's overlapping, so you'll need to select a circle and move it around until all the lines are untangled. Once you complete this task, you win.

One of the best things about Tangle is that it has unlimited levels, which means that there's no shortage of content to work through. While beating level 10 takes some skill, the game provides endless variations on levels, so you'll never get bored. Once you've had some practice with the game, you can try challenging your friends online in Multiplayer mode.

To add to the competitive nature of the game, there's an online Leaderboard where you can compare your times with anyone else who's playing Tangle around the world. There's even a Leaderboard Badge that allows you to show off your fastest times on the web.

If you're looking for an even greater challenge, Expert mode will give it to you. The levels in Expert mode are much tougher, providing a new level of difficulty for players to tackle. And, if you're the type of player who likes to track scores, you'll appreciate Tangle's Personal Leaderboard.

The game also features sound effects, which add to the overall experience. However, there are a few limitations to the game. For example, your scores aren't displayed on the online Leaderboard. Additionally, Tangle will only play all levels at any difficulty for 60 minutes. After that, the game will only allow you to play the first two levels.

Overall, Tangle is a great puzzle game for anyone who loves to be challenged. With its unlimited levels, variations, and online Leaderboard, there's plenty of content to keep players coming back for more.
