Shape Drawing: One Line Puzzle

About Shape Drawing: One Line Puzzle: 500 Hand-Drawn Levels, One Unbroken Stroke

Shape Drawing: One Line Puzzle is a puzzle game built around a single, strict rule: trace every dot and line in a picture using one continuous stroke, never lifting your finger and never crossing the same line twice. Every one of its 500 levels was drawn by hand rather than generated, so each shape has its own character. Several scenes show small white points scattered across a dark green background gradient. A green bar fills from left to right as lines are highlighted between circular nodes in several views of the game.

The journey starts with a simple three-line triangle and moves through houses, foxes, rockets, owls, castles, and eventually a 33-line snowflake. The challenge grows from the geometry itself — a loop that must be entered at exactly the right moment, or a crossing that looks open but leaves you stranded two moves later. There is no timer and no lives, so the pressure is purely logical. A wrong turn produces an immediate dead end, and progress saves automatically, letting you stop at level 6 or level 460 and return whenever you like.

How to Play Shape Drawing: One Line Puzzle: Trace Every Line Without Lifting

Press any dot and drag to draw the shape. The level is complete when every line has been covered exactly once. Trace into a dead end and the game tells you immediately — drag back along the path and try a different route.

Two in-game buttons give direct assistance: HINT draws the rest of the solution for you, and LEVELS opens the full level list. The speaker button mutes the sound.

Controls

• Press and drag (touch): Draw the line across dots
• Drag back over the previous dot: Undo the last step without lifting your finger
• Lift finger mid-line: Fails the attempt and resets the level
• Mouse: Draw and navigate on desktop
• H (keyboard): Activate the hint
• Portrait or landscape orientation: Both supported
