Single Stroke Line Draw

One line, every dot, zero room to retrace — can you clear the board in a single uninterrupted stroke?

You know that moment when a puzzle looks trivial and then quietly punches you in the brain? Single Stroke Line Draw lives there. The board gives you a tangle of dots joined by lines, and you have to trace every single segment exactly once, one uninterrupted stroke. No lifting, no retracing, no second chances on a line you've already inked. It takes about six seconds to understand and considerably longer to master. The first few levels are gentle enough: a square with a diagonal, a house shape, maybe a triangle with a tail. You'll glide through them and think you've got it. Then the game drops a six-pointed star with internal spokes, and suddenly you're staring at it like it insulted your family. That's the real fun — working out where to start, where to finish, and how to weave through the intersections without trapping yourself. I started sketching routes with my finger above the screen before committing, like a tiny cartographer. What kept me hooked is how cleanly it resets your head. There's no timer, no score pressure, just the line and the dots. The undo button erases your last move, not the whole route, which feels forgiving until you realize you've undone the same turn five times. If you like logic puzzles that reward patience over reflexes, this one's a quiet, infuriating gem.

Connect all the dots and complete the level

Odd-degree junctions are your starting and ending points — find them first. If a section looks like a dead end, save it for the finale. Trace the outer boundary mentally before you touch the screen. Undo is faster than restarting, so don't be shy with it. On later levels, pause and map the entire route before drawing. Treat every crossing as a potential trap — count how many lines meet.
