Line Puzzle 3D is a free online drawing puzzle game where you control a pencil to trace the outlines of 3D shapes with accuracy and steady hand control. Each level presents a rotating three-dimensional figure that you need to follow precisely, testing your spatial reasoning and hand-eye coordination in ways flat puzzle games simply can't match.

The gameplay gets progressively trickier as shapes grow more complex and the paths twist around corners you don't always see coming. Rotating the 3D object to get the right angle before drawing is half the challenge, making each completed level genuinely satisfying. The clean visuals give you instant feedback when your line drifts off track, so you always know exactly where you went wrong and can retry without frustration. Short levels mean you can squeeze in a round anywhere without losing progress.

This game is a great pick for fans of hypercasual puzzle games, brain training challenges, and creative drawing games online. If you enjoy 3D shape games, geometry puzzles, or satisfying line-drawing mechanics, Line Puzzle 3D delivers that in a casual, no-pressure format. It also works well as a focus and concentration game for players who want something mentally engaging but not overwhelming. Play free in your browser right now, no download or account required.
