About This Game

Single Line: Drawing Puzzle challenges you to complete each figure with exactly one unbroken stroke. Shapes start as elegant outlines with a missing path, and your finger or mouse must fill the gap in a single confident sweep without lifting, doubling back, or crossing your own line. Early designs ease you in, but the patterns soon twist into knots that demand genuine planning: you must mentally trace the route before your hand moves a pixel. It is the kind of quiet, addictive brain teaser that fits into any spare minute and quietly sharpens spatial reasoning.

How to Play

Press on the starting point and drag in one continuous motion to draw the missing line and finish the figure. You cannot lift your finger, retrace a section, or cross an existing line, so plan the whole route before you start drawing. Tip: begin from dead ends and corners, since those segments have only one way in or out, and if you get stuck, restart the shape to try a different order.
