2024 U.S. Puzzle Championship - Rules

The official purpose of the championship is to recognize the top U.S. puzzle solvers, to participate in the 2024 World Puzzle Championship in Baijing, China during the week of Oct. 13-20, 2024. Unofficial participation is open to all puzzlers world-wide, with nationality determined by citizenship, not residence.

 

For official Team USA qualifying, you must start at 1pm ET (10am PT) on Saturday August 10, and complete answer submissions within the 3 hour time limit (unless a hardship accommodation is granted in advance). Otherwise, the test timing is flexible, starting a 3 hour window any time and finishing before 10pm ET on Monday August 12.

Registration

All contestants must register to participate in this online championship, and must login to submit answers. See the Privacy Policy regarding our use of registration and other information collected by this site.

 

Test Procedures

Unlike most years, you can start this USPC test anytime between 1pm ET (10am PT) on August 10 and 10pm ET on August 12. However to be considered for Team USA qualifying, you must start immediately at the start of the test window (unless a hardship accommodation is granted in advance).

 

The proper procedure this is therefore slightly different than normal, so please read the following to ensure you are familiar.

 

  • Starting Friday August 9 (possibly sooner), download the 2024 Preview Puzzle Instructions and encrypted 2024 USPC files.
  • The preview instructions include a sample puzzle and solution, point value, and a description of the answer key format for each puzzle on the test. This will give you a head-start for translation or any other reasonable preparation, such as trying out puzzle types that you are unfamiliar with.
  • Go to the Start USPC page when ready to start. Once there, click either start button or link, which will reveal the USPC password and start your 3-hour clock.
  • Using the password, open the 2024 USPC PDF file and begin solving!
  • You will have 3 hours to solve as many puzzles as you can and submit your answers via the Answer Page. Your submission time is recorded with your answers. After you submit an answer or answers, the confirmation page will show your timestamp and remind you to check your Timer. You may then return to the Answer Page to view your submitted answers, continue solving, and to submit additional answers.
  • For your convenience, a separate Timer Window is available to show the current server time and a countdown to test end. The Timer is available from the right sidebar when you are using the "start", "password", or "answer" pages. This is a convenience, and not guaranteed to be accurate. You are personally responsible for submitting answers on time.

 

After 3 hours, your personal test period is over. In case of emergency or network lag, the Answer Page will continue to accept answer submissions; otherwise late answers are not scored. Please use the Timer to keep track of your time remaining.

 


 

Scoring

Your last Answer Page submission before the deadline will be time-stamped and scored. Your final score is the total of all points accumulated, including bonus. (One late submission will be considered, if within a grace period of 30-seconds of the deadline or when no other on-time submission is available.)

  • The scoring for each puzzle is given at the top of the page. A correct answer will earn the number of points indicated (which is a rough, relative indication of the time expected to solve the puzzle).
  • Leaving an answer blank will score 0 points.
  • There is no penalty for incorrect answers.
  • If you submit all answers completely and correctly, you will receive a bonus of 2.0 points per minute early (including fractional minutes) before your 3 hour limit.
  • All answers should be submitted within the 3 hours time limit. If a late submission is accepted, it will be subject to a prorated 2.0 point per minute penalty.

 

Ranking and tie-breaking will be based on the following rules in order:

  1. Most total points, including bonus
  2. Earliest final submission time

 

Outside Help

Outside solving help of any kind is not permitted. This includes but is not limited to: assistance of any kind from any other person; prepared notes, books, calculators, computers, or tools other than items explicitly permitted.

 

You are allowed to use writing implements, eraser, blank paper (including commercial graph paper), ruler, scissors, tape, and translation of Preview Instructions.

 

Judging

All entries and scores are subject to review for rules compliance. USA winners may be asked provide a copy of their passport ID page to prove nationality, and to sign an affidavit confirming that they did, in fact, abide by the rules of the competition. The organizers reserve the right to disqualify any contestant if, in their sole judgment, they believe the rules have been violated.

 

In case of a dispute, protest, or other judgment, the decision of the judges is final.

 

Technical Support

The organizers do not expect any technical problems with the operation of championship. If you do encounter a problem that is likely causing trouble for many contestants, check the USPC home page. If you have a problem that is most likely affecting only you, you may call the test hotline number: (+1) 650-302-4898. Officials will not, however, answer any questions regarding the puzzles themselves.

 

Results and Winners

The solutions to the test puzzles will be published here after August 12. Preliminary scoring will be emailed by August 13, and results will be published here before August 17.

 

The USA contestants with the top five unaudited scores will be notified within one day of the test. Within two days, all contestants will receive an email or online summary of their score, and will have a 1-day window to respond with any scoring protests.
