Euclidea

Euclidea is a fun and challenging game where you create your own geometric constructions! 127 Levels: From super easy to insanely hard, you'll keep going from one challenge to the next! 10 Innovative Tools: Let your creativity run wild in the world of geometry! Plus, there's "Explore" mode and hints to help you solve tough problems. Easily drag, zoom, and pan—it's all smooth! Each level you complete unlocks the next challenge. To access all levels, you need to earn stars! But if you prefer no restrictions, you can make a one-time in-app purchase to unlock everything. "Euclidea helps boost imagination, intuition, and logical thinking—skills that are definitely worth developing." – appPicker "Euclidea is a delight to play... Every math student should have it, and ideally, every adult would enjoy it too." – Non-Trivial Games About Euclidea Euclidea is a new way to learn, explore, and have fun with Euclidean geometry! Your task is to solve various challenges by using a straightedge and compass. If you create the most elegant solutions in the fewest steps, you'll earn the highest scores. Scores are based on lines (L) and elementary Euclidean constructions (E). Start Simple and Get Smarter! Don’t worry if you're not a math genius. Euclidea starts with simple challenges to guide you through the basics. Once you’ve mastered them, you'll face more complex, brain-bending puzzles like inner/outer tangents, regular polygons, and more. There are 120 unique challenges, organized into packs for easy navigation. Add Constructions to Your Interface When you learn key constructions (like angle bisectors or a non-collapsing compass), they automatically get added to the Euclidea interface’s shortcuts, saving time and making your drawings neater! Easily Drag, Pan & Zoom All constructions in Euclidea are fully dynamic. You can drag to adjust angles, lines, and radii. Zoom and pan effortlessly. This makes the game more interactive and helps you better understand the relationships between geometric elements, explore different options, and spot mistakes. Instant Automatic Precision Don't stress about precision—Euclidea automatically snaps points, lines, and circles to a clean interface! Additional Special Features A helpful “Explore” mode that lets you preview the figure you need to construct. A toolbox that expands as you progress—these tools are key to future challenges. Some challenges have multiple solutions, allowing you to try different approaches and have double the fun!

Select a Level: Choose a challenge from the level list to start your geometric adventure. Observe the Goal: Look at the target figure of the level and understand what needs to be constructed. Pick Your Tools: Use a straightedge, compass, and other tools to start building the geometry. Adjust Constructions: Drag points and segments to fine-tune, ensuring your figure meets the requirements. Earn a Score: Get a score based on the steps and lines used—aim to design the best solutions! Unlock Tools: Complete key constructions to unlock shortcuts, making future challenges simpler. Explore Mode: Use the Explore mode to preview the target and get a better understanding of the geometry you need to complete.
