  • All ties will be resolved by the earliest received submission, so send in your answers as soon as you know them. But try to be as accurate as possible—it usually takes close to a perfect score to win. 
  • Answers will be accepted until 11:59 p.m. (Pacific Time) on Tuesday, January 4, 2022, and only a member's first submission will be considered.
  • Spelling counts. The quiz is scored automatically by Google Forms, so make sure you spell your responses correctly. For player names, write the first and last name only in that order. Use a capital letter as the first letter of proper nouns. Do not use any accent marks or titles. For chess moves, use simple algebraic notation without a move number (e.g. Nf3). For fractions, use the most simplified (e.g. 1/2).
  • You can use any resources at your disposal to get the answers (engines, web search, comment section, phone-a-friend, etc.).
  • Provide your valid username and an e-mail for your answer receipts in the form.
