Our House of Darkness room would probably be a bit too intense for younger audiences. The other two rooms may work, but this depends on the 9 yr. old. Your average youngster may get bored since the puzzles are designed for adults, though there are some items that you will need to search for that kids seem to enjoy doing. We have also seen some children come up with ideas that the adults in the room didn't think of, and they were right. One thing to note is we require a full room booking if you bring in kids under 13 since it is a safety concern having strangers mix in with children.
Unfortunately this room is for ages 13+
