*** 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 triangle the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of those of the two other 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.

*** The tree ***
The Pythagoras tree is a fractal constructed from squares and right-angled triangles. Your Pythagoras tree grows up with each solved problem. Each tree is unique: no other tree has the same form. And after all levels are completed you will see its blossom. Everything depends on you. Good luck!

### 4/5 — Сложно

*2026-05-22*

Хорошая игра, но минус одна звезда потому что учитель постоянно говорит проходить ее всю, и при этом заявляет что лично знает создателя

### 3/5 — Great concept, lacking

*2026-04-20, version 2.34*

I have had these apps for years and always enjoyed the beginning of them. I purchased the entire collection, even tipped the creators. But I have to say that after a while, they just become frustrating. Why? Because you don’t build on any of the knowledge gained from level to level. Sure, it gets harder and harder, that’s fine. But eventually you have to look up answers online which don’t in any way elucidate the problem. I’ve passed levels, with help and on my own, that I am certain I could recreate, yet I don’t understand WHY it works. I wish this game were more educational. The glossary of terms starts out useful but eventually it doesn’t help at all. I love geometry, but I wish this made me appreciate geometry more. Please make it more educational. Perhaps by adding some info explaining WHY your solution works after you’ve input it. Some clues would also be helpful, not so much in finding the answer but in reminding us of the concepts that will lead us to the answer.

### 3/5 — Hatalı soru

*2026-03-07, version 2.34*

Paraleller bölümündeki 2.8 soru yanış 5 noktadan geçen geçecek şekilde iki paralel doğru oluştirmamızı istiyor. sorunun çözümü 4 nokta ile çözülüyor. onun dışında oyun iyi

### 5/5 — Отличная игра

*2026-01-17, version 2.34*

Хорошая игра

### 5/5 — Great game

*2025-11-13, version 2.34*

This game is free- and unlike many other free games that overload you with ads, this one doesn’t, and it’s nice that the developers actually care. The levels are a good difficulty: some are not too difficult, while some really make you think about how to use the grid to construct what it’s asking. Overall, it’s a great game.

### 5/5 — Actually free and fun puzzle game

*2025-10-25, version 2.34*

This app is a bit challenging, but extremely fun and addictive. It’s very educational as well. But the best part to me, is that it’s completely free. Zero ads, zero in app purchases, zero micro transactions. Just a simple game. Gotta respect it

### 2/5 — Очень сложно

*2024-12-20*

Быстро становится настолько сложно что ничего не приходит в голову. В итоге перебираешь все варианты. Уже кликер какой-то.

### 5/5 — Best maths game ever

*2024-10-07, version 2.34*

Teacher recommended this game I don’t regret getting it

### 5/5 — Лучшее приложение!

*2024-09-30*

Даю задания из приложения своим ученикам. Полезно и интересно! Ребята в восторге. Можно давать детям разных возрастов в зависимости от темы. Особый смак в том, что решений в интернете почти нет.
Рекомендую!

### 4/5 — A Surprisingly Engaging Trip through Euclidean Geometry

*2024-09-28, version 2.34*

I wish all proofs were so fun and easy
