Planar Puzzles is a captivating puzzle game developed by Mobile Gyro. This Android game falls under the puzzle category and offers a unique and engaging gameplay experience. The game revolves around planar graphs, which are graphs of multiple planes where the edges do not cross.

The main objective of Planar Puzzles is to arrange the vertices of the planar graphs in such a way that the edges of the planes do not intersect. Players can touch and drag the circles (vertices) to rearrange the planes and untangle the graph. A counter keeps track of the crossed edges, and the puzzle is considered solved when there are "zero" crossed edges.

The game is easy to learn but challenging to master, making it perfect for those who enjoy thinking-puzzle games. It offers thousands of puzzles to keep players engaged for hours, and the best part is that it is completely free with no limitations or restrictions. While the game works on phone-sized screens, it is recommended to use tablet-sized screens for an optimal experience.

Planar Puzzles is a must-have addition to any game library for puzzle enthusiasts. Give it a try and see if you can untangle the graph!
