How to play
- Goal
- Join every circle into one tree, matching each numbered branch count.
- How it ends
- The chart finishes when every number matches, every circle is connected and there is no loop. Undo and Erase allow corrections.
- Record
- Your first unassisted finish keeps your time for that chart; later plays are practice.
- Join only immediately horizontal or vertical neighbouring circles with one branch per pair. No diagonal or skipped circles.
- Match every numbered circle’s exact branch count. Blank circles have no number constraint, but every circle must connect.
- Keep one connected tree with no loop. A finished tree on N circles has N−1 branches. Cross notes are optional and need not fill unused edges.
- Choose Line and tap an edge, or drag through neighbouring circles and release. Alternatively select successive neighbours and press Draw. One released route is one Undo. Note excludes an edge; Erase clears it.
- Restart preserves the first clock. Reload preserves an unfinished attempt and Undo; its resumed finish stays local. A clock change or computer suspension makes the current time local. Replay starts fresh and preserves your first time.

| 1 / 2 / 3 | Line / Note / Erase |
| Z / Y | Undo / Redo |
| R | Restart confirmation |
| Escape | Cancel a draft, close a dialog or return to the atlas |

Tips for Edaburi
- Start with corners A corner numbered two needs both neighbours.
- Count available neighbours A four in the middle needs every touching branch.
- Avoid a loop If two circles already belong to the same branch group, joining them closes a loop.
Questions about this game
Do blank circles have a hidden number?
No. Their only constraints are belonging to the tree and avoiding loops.
Must every unused edge have a cross?
No. Crosses are optional notes; the selected branches determine completion.
May a branch skip a circle?
No. Only immediately neighbouring circles can connect.
Can replay improve my first time?
No. Your saved first finish remains unchanged; replay is practice.
All charts are open. Reload retains an unfinished original attempt, Undo and its clock; resumed finishes stay local. Practice starts fresh and preserves your first time.

About Edaburi
Draw branches on a lamplit living-bough folio. Each numbered circle tells you exactly how many branches touch it; blank circles still belong to the tree.
All 160 original charts are open: eight 3×3, fifty-six each at 4×4 and 5×5, and forty 6×6. Every chart has one independently verified ending and a complete logic proof.
Your first finish keeps its time. An uninterrupted verified first solve can claim the named fastest time; replay is practice.
