Reading the Outline
Each round shows a dark silhouette against a clean background. Your job is to draw a single straight line that matches one side of the hidden shape. There is no timer, so you can study the outline and consider angles and lengths before committing. The challenge comes from observation, not reflexes.
Drawing and Adjusting
Using a mouse or finger, you drag to create a line. You can reposition and rotate it before locking in your guess. Once you confirm, the shape appears in full color and your line is shown against its edge. That immediate reveal tells you exactly how close you were and helps you adjust on the next attempt.
Shape Variety and Difficulty
Silhouettes range from simple geometric forms to more intricate outlines. Early shapes tend to have straight edges that are easier to match. Later puzzles introduce curves and irregular angles, so you need sharper estimation. The gradual increase in difficulty keeps rounds from feeling identical without becoming frustrating.
Session Length and Access
Each puzzle takes only a minute or two, which suits short breaks. There is no story mode or lengthy tutorial—you start a round, make your guess, and see the result. The minimal interface loads quickly in a modern browser, and no download, registration, or personal information is required.
