There are often buttons in the secret room. You must press them when you see them. This is also a clue. With the first and second clues, there will be more and more clues to help players.
3. Pay attention to the light. Turn on the flashlight when you see it, and the light you shine is likely to have clues.
When you see the mirror, try to reflect the light with the mirror. Maybe there will be things like pictures and texts, and such things will also become clues.
5. Pay attention to the puzzle. When a player finds a puzzle, he needs to find the remaining puzzles, put them together and find clues on the whole puzzle.
6, warm reminder, when you can't find clues when you escape from the secret room, you can seek off-site help.
