Trace a single continuous trail that visits every node exactly once.
Rules
Start from any node. Follow the connecting lines to move between nodes. You cannot revisit a node you have already passed through.
Controls
Tap a node to begin your trail. Tap connected nodes to extend it. Tap the previous node to backtrack one step. Use Clear Trail to start over.
Tips
Look for nodes with few connections - they often need to be visited at the start or end of your trail. Plan ahead and think about which paths leave the most options open.
