Placement reference
Match every touching edge. Open meets open; closed meets closed.
Connect at least one pathway. Path-to-Path colors may differ.
A Path directly beside the Center must match the color of the
Center edge it connects to. These spaces are not reserved for any
player; personal and Community Paths follow the same Center color
rule.
Cards are fixed after placement. Faint tiles are alternative
locations for one selected card.
Rooms connect to at least one open Path and cannot share a side.
Another Room side may face a closed Path edge, in either placement
order. That closed edge is not a route. A Wall Utility blocks the
whole Path card.
If no eligible personal card can be placed, or the pending
Community card cannot be placed, construction ends in a neutral
deadlock.
