LineFlow

LineFlow is a puzzle game built around the classic "one stroke" idea.

In each level you draw a single, continuous path that travels every edge exactly once and visits all nodes. Rules are simple: start at any node, move along the existing edges, and never reuse an edge. When every edge is covered with no repeats, you clear the level.

The game has 20 levels with gradually increasing difficulty—from simple shapes like triangles and squares to more complex graphs. It works both as a quick casual game and as a brain-teaser for players who like logic and planning.

If you get stuck, you can use "Hint" to see a suggested next move or "Undo" to go back one step and try another path.

You can sign in with Google to keep your experience consistent across devices (where sync is supported).

The interface is clean and easy to use: tap or swipe to connect nodes, with clear feedback when you finish a level.

Whether you want a short break or a focused puzzle challenge, LineFlow offers a compact, satisfying experience.
