Every box contains a Halloween-themed question. Answering a question will reveal the question in every adjacent box. Your goal is to reveal all the boxes.
Answering a question where the adjacent box is already revealed will not trigger an answer. Due to the nature of this quiz, answers cannot be revealed when the quiz is done. However you can find the answers to all the questions in the comments.
