Hidden Messages

One of the most common escape room puzzles is a message or code hidden in what otherwise looks like a normal note. The basic approach is to differentiate some subset of the letters or words. Experienced players learn to look for idiosyncrasies in any text they see.

	Highlight Letters Highlight letters using bold, colors, or other font changes.
	Capital Letters The capital letters in the message don’t follow grammar. That’s because they spell out a secret.
	Numbers for Letters Hide a number code by replacing letters in a message with similar looking numbers.
	Number Words Numbers that naturally belong in a message form a code.
	Rotated Letters Spell out a secret word by rotating or flipping letters.
	Misspellings Hide a phrase in a note by intentionally misspelling words.
	Code-Word Lookup A meaningless message reveals a clue when paired with a separate list of code words.
