About this game

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

One of the best games I've played, and the best part is that it's not just a game. This is a fantastic implementation of real geometry fundamentals that builds from the ground up a sense of geometric proof. I got stuck at some point and it was hard to go back and pick up where I left off - but replayability is not necessary when a game leaves such a profound memory.

The game could offer a bit more help, especially when first starting. Also offer help throughout the game. I understand that part of the experience is to figure it out on your own, but sometimes getting lost on a problem with no help is very frusterating, and without the answer, you can't progress to the next problem...other than that, it is a great designed game and is unique in every single way and different from any other game I've ever encountered. Thank you to the developers and great job!

NO INTRUSIVE ADS. Get ready to (re-)learn geometry from a whole new angle.*sunglasses* Wait, don't go yet... You get to draw cool stuff! Draw on your screen to match the diagram. Beginning with points, lines, and circles, more elaborate drawing tools and diagrams are discovered. Requiring ALL stars (including the hidden Vs) to progress is often difficult but video solutions can be found.
