One-stroke puzzle — How to play and useful tips
Use every edge exactly once in 72 original graphs. Tap connected points one at a time without keeping your finger down.
Controls
- Choose an outlined starting point, then a point connected by an unused edge.
- Use Undo to reconsider a route that gets stuck.
Playing tips
- Keep access to unused edges instead of closing off your route too soon.
Common questions
Can I revisit a point?
Yes, but an edge cannot be used twice. A crossing without a marked point is not a place to turn.
Can I resume later?
