CYDI is a free shape drawing game that runs entirely in the browser. There is nothing to download, no account to create and no drawing tablet needed - a mouse, a trackpad or a finger is enough.
Pick a category and work through it shape by shape. Geometric shapes come first, from a plain circle and oval through triangles, pentagons and heptagons to multi-point stars, spirals, waves and gears, followed by categories like symbols, the English alphabet, nature, food and sports. Every shape flashes up as a target, you redraw it freehand, and you get a scored side-by-side comparison right away. Clearing a shape unlocks the next one in its category, so the targets get harder as your hand gets steadier.
Best scores are saved per shape in your browser, which makes it easy to come back and beat your own record on the shapes that beat you.
Once a shape stops beating you, the same drawing and the same scoring work with other people: play a multiplayer drawing game against friends on their own devices, or a two-player game taking turns on one phone.
