Trace every edge in a network exactly once and discover the route that completes the picture.
This quiet puzzle game is built for short sessions. Each level gives you a small network of nodes and lines. Press a node, drag through connected nodes, and watch your path become bright ink. You can revisit ordinary nodes, but each edge may be used only once.
Four chapters introduce new ideas at a comfortable pace:
• Open routes let you choose where to begin.
• Starting point levels make the first move part of the puzzle.
• Ordered marker levels ask you to visit numbered nodes in sequence.
• One-way levels add arrow-marked edges that must be followed in the correct direction.
There are 90 handcrafted levels, a rotating daily challenge selected from the built-in archive, personal best times, and progress badges. If a route closes too early, your ink remains on the board so you can understand the decision and undo the last segment. Hints offer a small strategic nudge without revealing the complete route.
The game is designed to be played offline. Progress and preferences stay on your device. There are no accounts, ads, payments, leaderboards, or external content.
