Trace every connection exactly once in a collection of calm, compact route puzzles. Plan your path, keep moving through connected nodes, and avoid leaving unused lines behind.
Explore 90 built-in networks across four chapters:
• Choose a valid starting point in open-route puzzles.
• Follow a clearly marked starting node in later networks.
• Visit numbered waypoints in order.
• Follow arrows on one-way lines.
Touch a node and drag along a connected line. A traced line stays visible and cannot be used again, while nodes may be revisited when a route allows it. Lift your finger to keep your progress, undo the last segment, or restart after confirming. If a route closes too soon, review the blocked node and remaining lines.
Choose a starting-node clue or a next-line suggestion. Each hint explains why that choice helps without revealing the complete route. Complete a network to see your time, undos, hints, and personal record. Finish without hints to earn a badge.
Browse chapter maps with real network previews, rule tags, completion marks, and favorites. A local daily route rotates predictably through the built-in puzzles. Preferences include drag snapping, trail style, sound cues, completion motion, a dark theme, and direction arrows.
The game works offline. Progress, preferences, favorites, and records stay on your device. There are no accounts, ads, purchases, online leaderboards, or external content.
