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

Euclidea user reviews :

The puzzles are actual math problems. Further puzzles build on the knowledge gained from previous ones. The drawback is that some puzzles are insanely hard, and the game requires you to perfect earlier stages in order to progress. Some of these “near impossible” puzzles will block your progress and you are practically required to look up the solution. It either requires cheating, or you’ll be stuck not being able to play the rest of the game.

Excellent fun and sometimes very challenging. Be prepared to spend a long time finding optimal solutions (or pay) to unlock higher levels! One small niggle: the app quite unnecessarily uses full screen mode, hiding the status bar and soft buttons, and there is no way to disable this.

Excellent challenging game. Impressive coding how it always “knows” whether a solution is exact. Shortcomings: a) why not show which puzzles have multiple solutions b) for those of us who don’t live and breathe geometry, the Logical / Elemental dual scoring is somewhat opaque.

Super fun to practice geometry. Wish I could go through euclids proofs, also I don’t like the idea of needing to find a specific proof to continue (i.e shortest proof) and that sometimes it requires knowledge of theorems not yet proven in game. Google saves you then but still
