*** About ***
XSection is an introduction to solid geometry. It teaches you how to perceive
2D representation of polyhedrons, lines, and planes from 3D Euclidean space.
No calculations, a bit of theory, and a lot of practice.

*** Is this game for you? ***
XSection follows Euclidea/Pythagorea series of geometric games.
With all these apps you can become a real Geometry Guru.

*** 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 Question (“?”) button in a problem statement.

Awesome challenge!

Puzzles are tough but possible and often imaginative, which I really like. The instructions can be a bit confusing, especially if you don't know much geometry, but other than that, the concept is really cool. I'd like to see some puzzles where we are allowed to use certain angle tools (like constructing a 45 degree angle anywhere)

For the spatial afficianato

Think you’re good at geometry. Well this challenging little gem will keep you awake at night. Any experience in mechanical drawing will give you a leg up.

Great mind exercise

Good exercise Of the good old days when descriptive geometry was king.

I like this!

I like this app very much. It makes my brain to think. And it is interesting! Thanks!

Awesome!

Lots of fun and challenging. I'm hoping that new levels will be added, but the number of levels included is well worth the price. I'd be willing to pay for more!
