*** About ***
Pythagorea is a collection of geometric puzzles of different kind that can be solved without complex constructions or calculations. All objects are drawn on a grid whose cells are squares. A lot of levels can be solved using just your geometric intuition or by finding natural laws, regularity, and symmetry.

*** Just play ***
There are no sophisticated instruments. You can construct straight lines and segments only and set points in line intersections. It looks very easy but it is enough to provide an infinite number of interesting problems and unexpected challenges.

*** All definitions at your fingertips ***
If you forgot a definition, you can instantly find it in the app’s glossary. To find the definition of any term that is used in conditions of a problem, just tap on the Info (“i”) button.

*** Is this game for you? ***
Euclidea users can take a different view of constructions, discover new methods and tricks, and check their geometric intuition.

If you have just started your acquaintance with geometry, the game will help you understand important ideas and properties of the Euclidean geometry.

If you passed the course of geometry some time ago, the game will be useful to renew and check your knowledge because it covers most of ideas and notions of the elementary geometry.

If you are not on good terms with geometry, Pythagorea will help you to discover another side of the subject. We get a lot of user responses that Pythagorea and Euclidea made it possible to see the beauty and naturalness of geometric constructions and even fall in love with geometry.

And do not miss your chance to familiarize children with mathematics. Pythagorea is an excellent way to make friends with geometry and benefit from spending time together.

*** Main topics ***
> Length, distance, and area
> Parallels and perpendiculars
> Angles and triangles
> Angle and perpendicular bisectors, medians, and altitudes
> Pythagorean Theorem
> Circles and tangents
> Parallelograms, squares, rhombuses, rectangles and trapezoids
> Symmetry, reflection, and rotation

***Why Pythagorea***
Pythagoras of Samos was a Greek philosopher and mathematician. He lived in 6th century BC. One of the most famous geometric facts bears his name: the Pythagorean Theorem. It states that in a right-angled triangle the area of the square on the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares of the other two sides. While playing Pythagorea you often meet right angles and rely on the Pythagorean Theorem to compare lengths of segments and distances between points. That is why the game is named after Pythagoras.

Comments on Pythagorea for Android

★★★★★ Adam Smith · Feb 10, 2025
Amazing geometric puzzles and no ads. Such a unique and rewarding app. Thanks for making this available!
★★★★★ John Robins · Jan 8, 2025
A terrific game that helps keep math skills sharp. I've played and reset progress many times over the years, and I'm still finding novel ways to solve some of the puzzles.
★★★★★ Peter Arwanitis · Jul 10, 2025
Looks simple, but long list of math / geometry puzzles to keep you challenged and motivated. Helps me during vacation to relax, but YMMV Sometimes confuse myself due to too many "helper lines" to construct, but hey. Try to find a simpler approach and => free and no ads <= Should be part of education :) (and it might be that the in game info requires Internet, got some black screens being offline \o/ still the game works fine!)
★☆☆☆☆ BLANK · Mar 19, 2025
It doesn't try to teach you anything, you have to have the knowledge on how to find/construct certain points or just blindly guess. This app should teach you geometry and methods of finding points instead. You can just completely skip levels too without any hints or seeing the solution after.
★☆☆☆☆ Michael Piotto · Jun 15, 2026
The game only wants specific solutions. Fix your game, it's pretty easy to write code to detect a specific shape with specific parameters.
★★☆☆☆ Cloud Rain · Dec 21, 2024
Sometimes it is impossible to create a parallel without constructing a point by creating a line first so that the pointcus on the intersection. Then the system does bot allow you to delete the first line for assistance
