Well in this riddle there's a word or phrase as an answer, its from a game, I cannot solve it so far(over a week trying). The riddle is the following:
"Try not to move, 3 knocks and you're outside."
Context: This is a game where you get a riddle and you need to answer a word or a sentence in order to pass to the next level, there are no clues. Example of last riddle was : “The first in the series, since Daniel became a legend” and the answer was “Harry Potter and the Philosopher's Stone”.There is no credit needed, it is a family game...
