The map exists in the rules. Whether to print it is up to you.
You reached your destination.
A cube of rooms, each addressed by a 3-digit number — floor, row, column. Each keycard carries four digits (two on the top edge, two on the bottom). Hold two keycards and overlap them so three digits show across the top and you've named a room. Only certain digit patterns yield a valid room; that subset, plus the adjacency rules between rooms, is the map — and the cards in play decide how big the cube is.
Rotate, flip, or swap the keycards — or, when there is more than one kind, trade a held card for another with Card — to unlock new rooms, then click an unlocked neighbor to walk there. Reach the ★ destination to win. Or use Unlock to ask the cards to form any specific room number — the panel either orients them or tells you the room is impossible.
