IOS Review #107: Euclidea

Title: Euclidea
Developer: Horis International Limited
Platforms: IOS Universal
Price: Free
Math can be difficult and frustrating for some people, and the very notion of math puzzler probably is enough for people to dismiss some games. But Euclidea isn't like most math-based puzzlers; rather than numbers and addition and subtraction, it's all about geometry, constructing figures and shapes. There are quite a few games that feature similar concepts, usually physics-based puzzlers where you need to build supports or structures, but Euclidea distills that idea down its purest, most minimalist form, with an elegant presentation and easy-to-use controls.
Euclidea starts out simple, easing you into its collection of geometric brainteasers by teaching how to create line segments, select points, draw circles. And then gradually, the challenge begins to increase, as you use intersecting circles to create equilateral triangles and perfectly bisect lines.

But the game isn't completely merciless. For several of the more common and tricky actions like bisecting angles and creating parallel lines, once you learn how to construct it once, Euclidea provides tools that automatically perform the action. Thanks to the game's controls and clean UI, the challenges of the puzzles are about figuring out how to accomplish a task rather than in the execution
You'll need those tools, because while Euclidea may be easy to control, it certainly isn't easy. Figuring out to create a perfect hexagon within a circle or trisecting an angle requires you to think ahead, understand how points and intersections and line segments all interact and can be used together. It may sound scary, but the game does a good job at introducing its concepts and making sure you can use them before throwing the tricky challenges at you. Like math in general, Euclidea's puzzles are cumulative, building upon what you figured out before and challenging you to use that knowledge in new ways.

Euclidea is visually sparse, black lines against white, but there's something appealing and satisfying about the symmetric patterns of lines and arches created from your attempts to solve puzzles, how distinct shapes emerge from the mess of intersecting and overlapping figures.
Euclidea is free to download, with only an IAP to remove ads. You can download the game here.
And if you enjoy this one, the developer released Pythagorea earlier this year, a similarly geometry-focused puzzler with its own unique twists.
