Self-Referential Quiz (Puzzleship)

About Self-Referential Quiz (Puzzleship)

There is nothing to know in advance. Each question refers to the quiz's own answers, either counting them or pointing at a specific question, and your answers must make all of them true together. Most questions cannot be settled alone, which is what makes it a puzzle.

Questions that point at one specific other question are easier to handle than ones counting totals, and a question that points at itself often has only one consistent option. Assuming an answer and following it until something breaks is a fair method here, since a contradiction eliminates that option for good.

Puzzleship publishes six quizzes of Self-Referential Quiz a day, graded from very easy to ultra hard. Each day's quizzes are numbered and dated, the same for every player, and appear at midnight in your own time zone; earlier days stay playable in the archive. The site is free with ads, and a premium plan removes them.
