Description
Euclidea is a FUN & CHALLENGING Way to Create Euclidian Constructions!
127 Levels: from very easy to really hard 10 Innovative Tools "Explore" Mode and Hints Easily Drag, Zoom & Pan
New levels are unlocked as you solve the previous ones. You can complete the whole game only if you earn all the stars. But you can buy an IAP that removes this restriction.
“Euclidea has been shown to help with imagination, intuition, and logic, all wonderful skills to develop.” – appPicker
“Euclidea is an absolute joy to play…it’s a game that every math student should have and, in an ideal world, every adult should like.” – Non-Trivial Games
***About Euclidea*** Euclidea is a brilliantly original way to learn about, explore and have fun with Euclidian Constructions! Your task is to solve interesting challenges by building geometric constructions with a straightedge and compass. If you design the most elegantly simple solutions in the least number of moves, you’ll earn the highest scores. Solutions are scored in lines (L) and elementary Euclidean constructions (E).
***Start Simple and Get Smarter!*** Don’t worry if you aren’t a math wizard. Euclidea starts out with simple challenges that guide you through the basics. Once you master the fundamentals, you’ll move on to tougher, more mind-bending challenges such as inner/outer tangents, regular polygons, and more. There are 120 unique challenges in total, which are organized in packs for simpler navigation.
***Add Constructions to Your Interface*** When you learn certain significant constructions – such as angle bisectors, non-collapsing compass, and so on – they are automatically added to the Euclidea interface’s shortcut, which helps you save time and allows you to create clean, uncluttered drawings.
***Easily Drag, Pan & Zoom*** Euclidea-created constructions are completely dynamic. As such, you can drag to adjust angles, lines, radii and so on. You can also easily zoom and pan. This not only makes the experience more interactive, but it allows you to more deeply grasp the relationships between geometric elements, explore various possibilities, and analyze errors.
***Instant, Automatic Precision*** Don’t worry about spending time or effort trying to achieve perfect precision, because Euclidea automatically handles that task by pinning points, lines and circles to the app’s clean interface.
***Additional Special Features*** > A helpful “Explore” mode that allows you to see the figure you need to construct > An inventory of tools that you create as you progress – you’ll need these to solve future challenges > Some challenges can be solved in more than one way, which means you can try a different approach and have even more fun

A really fun and challenging way to learn math and geometry
★★★★★Sebastian Wieland· Feb 9, 2026
Great mathematical puzzle game! Please add a dark mode :)
★★★★★Generic DevTexture· Feb 3, 2026
It's a satisfying game. I mostly went into this game to learn more about geometry, and I got what I wanted. The puzzles are fun they're not too hard (for me at least) I also like how the game doesn't force you to only have a limited amount of moves, so you can experiment as much as you like till you can find the right answer. Also, idea for the developers... How about a sandbox mode? ’D Where you're free to draw anything and be able to analyze their relationship with other objects you constructed.

I don't get it. I completed the first puzzle following the guides (3 stars). No guides in the second puzzle, so I copied the first puzzle's guides to draw a 60° angle. No award, no completion, zero stars. What's the point?
★★☆☆☆Bumi· Mar 25, 2026
It's fun and challenging but on level 2.8 (tangent to circle at point), the E star is impossible to get. Constructing it requires at least 4 step when using straightedge and compass, not 3. I believe there's miscount of the required move on several other levels, but this one is the easiest to spot.
