Case briefing
Christmas clues
Arrange the nine cards into a 3×3 grid. North is up. Read each clue carefully; every fact matters.
How to play: Select any two city cards to swap their positions. When your arrangement satisfies every clue, check the grid to close the case.
What the clue language means
Adjacent cards share a side, never just a diagonal. “Somewhere left/right” compares columns; “above/below” compares rows. Neither requires immediate neighbors or alignment on the other axis unless stated. “In a row/column between” means strictly between on that axis; the other axis is unrestricted. “Exactly one” and “either … but not both” exclude both alternatives being true and both being false. Combine every clause, including those separated by a semicolon.
