Description
Master different methods and solve puzzles.
* More than 100 tasks: from basics to challenges * 11 chapters to explore * Built-in glossary with geometric terms * Step-by-step instructions * Easy to use
XSection is a trainer of solid geometry problem solving. It teaches you how to perceive 2D representation of polyhedra, lines, and planes from 3D Euclidean space. All the problems can be solved without complex calculations. The app contains the required theory facts and explanations. If you forgot a definition, you can instantly find it in the app’s glossary.
XSection is a perfect way for students to practice before tests or exams and to improve your spatial imagination. The app will not allow you to create an impossible object: for example, to "intersect" skew lines (which is a typical error when constructing cross sections on paper).
The best way to learn to solve math problems is to solve them a lot.
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
XSection follows Euclidea - Pythagorea - Pythagorea 60° series of our geometric games. With these apps you can become a real Geometry Guru!
Starting from the 8th chapter levels are unlocked at 4-hours interval. But you can buy an IAP that removes this restriction.

Great, easy to learn puzzle game. Each geometric puzzle prepares you for the future ones, and the puzzles get progressively more challenging. Finding solutions is quite satisfying, can't wait to see more!
★★★★★Natalie F· Feb 11, 2025
Amazing game! I've never dealt with 3d geometry before and this is a fun way to learn. I wish I could use different colors for different lines but overall this is just a rare good free thinh
★★★★★Jake Allison· Dec 7, 2025
Awesome game. Challenging but incredibly simple once you can see the solution. Wish it had more levels.
★★☆☆☆Danksta Danksta· Oct 5, 2021
Its kind of mystery from the start what the actual purpose of the app is. I could find no clear direction on what to actually do or if I was using the app with any real success. Instruction would be helpful because it was sort of confusing. If the desired planes were more clearly defined in relation to the starting base, maybe just a few more colors, it would help for reference when constructing from scratch. Really awesome concept and actually quite fun if you can find the patience to use it

Quite a good concept, but needs a little work. There should be more definitions given. I had to Google what skew to a line meant before I found the level glossary (which should be directly accessible from the level screen). And I'm not very happy about having to arbitrarily wait 4 hours between level 8.1 and 8.2, and I'll be even less happy if I have to wait between levels going forward. Edit: Confirmed. 4 hours wait before every level after 8.1, this is ridiculous. Dropped rating.

No hints. If you don't know how to solve a puzzle, you are stuck. There is no hint. Uninstalled after 3 levels, maybe I am too stupid.
