Quick answer: Coordinate clues become much easier once your team has the Map Room. Treat each one as a navigation problem first, then a local interaction problem.
Read the clue carefully
Copy both numbers in the order shown. Start with nearby landmarks rather than trying to walk directly through terrain with no reference point.
Two-team method
Keep one player at the map and one at the location; use a radio or agreed signals; confirm the surrounding landmark before testing every object in the area.
Common mistakes
Reversing the coordinate order; leaving the map reader without a way to communicate; searching only obvious boxes instead of nearby surfaces or buttons.
