One Line: One Stroke Puzzle

One Line: One Stroke Puzzle is a calm, minimalist line puzzle where every move matters. Draw through every line in one continuous stroke, without lifting your finger and without tracing the same line twice. Plan your route, choose the right turns, and solve each shape with a single connected path.

Think. Draw. Solve.

The rule is simple. The challenge is finding the route. Start from a dot, follow connected lines, avoid dead ends, and complete the whole figure in one stroke. Some puzzles are geometric, some form recognizable pictures, and some use curved paths that change how you read the board.

Two ways to play

• One Stroke — Follow the classic one-stroke rule. Lift before completing the figure and the current attempt resets.
• Relax — Keep your progress when you lift your finger and continue from the glowing endpoint.

Built for thoughtful play

• Clean, touch-friendly controls
• Undo and Restart when you want to rethink a route

• Skip a puzzle and return to it later

A puzzle game you can play at your own pace

There are no timers forcing you to rush. Take a moment to study the intersections, think about where a path can end, and then draw. The difficulty grows through more interesting routes, branching choices, loops, intersections, and unexpected shapes rather than simply making everything bigger.
