How to play
- Goal
- Draw one closed loop through every dot, using all fixed segments.
- How it ends
- The chart finishes when every dot has two lines and all lines form one loop. Undo and Erase allow corrections.
- Record
- Your first unassisted finish keeps your time for that chart; later plays are practice.
- Join horizontally or vertically neighbouring dots into one closed loop. Every dot needs exactly two links.
- Keep all fixed segments, identified by their diamond marks. They cannot be erased or crossed out.
- Do not branch, skip a dot or close separate small loops.
- Tap an edge or drag through neighbouring dots and release. A whole route is one Undo. Alternatively tap successive dots and press Draw. Cross notes are optional.
- Restart preserves the first clock. Reload preserves an unfinished first attempt and Undo; its resumed finish stays local. Reopening practice starts fresh.

Tips for Grand Tour
- Start at a corner A corner has only two possible exits, so both belong to the tour.
- Keep fixed links The diamond segments are already part of the answer.
- Leave the tour open Do not close a small loop while dots remain outside it.
Questions about this game
Must every dot be visited?
Yes. Every dot must have exactly two links in one closed tour.
Can I erase a fixed segment?
No. Its diamond identifies a mandatory link.
Are cross notes required?
No. They only help you remember edges you have ruled out.
Can replay improve my first time?
No. Your saved first finish remains unchanged; replay is practice.
All charts are open. Reload retains an unfinished first attempt, Undo and its original clock; resumed finishes stay local. Practice reopens fresh and preserves your first time.
