How to play
- Goal
- Match every room’s pin count and connect all rooms through shared pins.
- How it ends
- The rooms form one connected network and every printed count matches. Cross marks are optional; mistakes can always be undone.
- Record
- The fastest first unaided solve of each chart is recorded.
- Tap grid points to place pins. Each room’s number counts every pin inside or on its boundary.
- A pin at a shared boundary counts in every room it touches. A junction can join three or four rooms at once.
- Every room must connect to every other room through shared pins. The pins themselves do not have to touch. A blank room has no count constraint.
- Pin toggles a pin, Cross marks an unused point as a note, and Clear empties one point. Cross marks are optional for completion.
- Undo and Redo change one entry. Restart keeps the first clock running; replay after a finish is Practice.

Tips for Heyapin
- Count shared pins A junction pin belongs to every room meeting there.
- Watch full rooms Once a room has enough pins, its other points must stay empty.
- Keep a way through Matching totals is not enough: each room still needs a connection to the network.
Questions about this game
Must the pins touch?
No. The rooms connect by sharing pins; the pins themselves need not be adjacent.
Are boundary pins counted twice?
A pin counts once in each incident room, even at a junction of three or four rooms.
Must every empty point have a cross?
No. Crosses are optional notes and do not count as pins.
Does Restart reset the clock?
No. The first clock keeps running. Replays after a finish are Practice and preserve the first time.
Pins, notes and Undo save in this browser. The first clock starts when a chart is selected. Reloaded attempts stay local; replay is Practice and preserves the first finish.
