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.

*** Main topics ***
> Prisms, cubes, parallelepipeds, and cuboids
> Pyramids and tetrahedrons
> Diagonals of polyhedrons
> Cross sections
> Diagonal sections
> Parallel and central projections
> Method of traces
> Method of inner projection

### 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)

### Love this dev

Every app I've tried from these guys is phenomenal. Great, innovative learning apps. I can't put them down. So much potential here - can't wait to see what's next.

### 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!
