euclidea

Euclidea is a geometry puzzle game and educational platform that teaches Euclidean constructions through a collection of interactive puzzles. The game models a classical straightedge-and-compass environment, where players construct geometric objects using a restricted set of tools and operations that reflect standard Euclidean procedures. The focus is on logical sequence and exact construction rather than trial-and-error guessing.

In each puzzle, players are given an initial configuration of points, lines, and circles and a target element to construct. Participants perform steps such as drawing lines or circles, locating intersections, or constructing midpoints and perpendiculars, all within the constraints of the tools provided. The objective is to reproduce the target with as few moves as possible. Submissions are scored for efficiency, speed, and accuracy, and the game commonly offers hints and validations to assist progress.

The platform features a large catalog of levels arranged from beginner to advanced, covering topics such as perpendicular and parallel constructions, angle bisectors, tangents, and centers of triangles. It also provides guided tutorials and explanations to illuminate the geometric ideas behind each solution.

Euclidea is used in education and self-guided learning to promote understanding of geometric reasoning, problem-solving strategies, and algorithmic thinking. It is available on multiple platforms, including iOS, Android, and web browsers, allowing learners to practice geometry anytime, anywhere.
