TracePath

Untangle a network one careful move at a time. Drag from node to node and cover every line exactly once without lifting the thread between connections.

Explore 90 fixed levels across four rule chapters:

Any start: choose a starting node on a looping route.
Fixed start: plan from a clearly marked entry.
Ordered signals: visit lettered nodes in sequence.
One-way lines: follow arrowheads through directional links.

Every level has a valid route. Lift your finger to keep your progress, undo a segment when you want to rethink, or restart after confirmation. If a route closes too early, review the path on the board, see the final decision point, and try a different approach.

Use two levels of hints for a start suggestion or next-line reasoning without revealing a complete solution. Finish to see your time, reversals, hint count, and personal best. Save challenging routes as favorites, follow chapter progress, or take on a daily route that rotates predictably from the built-in puzzles.

Choose drag assistance, glowing ink, sound, motion, theme, and helper arrows in Preferences. No account or network connection is needed. Progress and settings are kept locally on your device.
