Underneath

A simple hiding place is a message underneath another object. The object can be a simple prop such as a plate or cup. For example, your escape room might have this normal place setting.

The players are expected to search around for clues. Simply lifting up the objects reveals a hidden clue.

This is a simple puzzle that encourages players to interact with the objects in the room. Players usually find the clue simply by picking up and examining objects. The clue gets revealed secondhand as players move things around.

The hiding place works best when hidden underneath a prop that is not otherwise needed. The prop should be easy to move and is easy to handle.
