General Rules edit

Mostly from WPC IB.

Scoring and Bonuses edit

  • Individual Rounds: A bonus of 10 points for each full remaining minute will be awarded to any competitor who correctly solves all puzzles in a round.
  • Team Rounds: A bonus of 40 points for each full remaining minute will be awarded to any team who correctly solves all the puzzles in a round.

If a single “minor” error (as determined by the judges) is present in a round submitted for bonus, 60% may still be awarded to the competitor or team.

Individual Playoffs edit

There were no individual playoffs this year. Instead, there were five mini-playoffs that focus on different puzzle genres. Rules from the IB:

"The top three finishers in Number Placement (Rounds 2-4), Object Placement (Rounds 5-7), Shading (Rounds 11-13), Loop/Path (Rounds 14-16), and Region Division (Rounds 18-20) will be invited to play in a three puzzle playoff in front of an audience to determine the best solvers of these puzzle styles.

In the mini-playoffs, the three players will all start at the same time. The three puzzles will be solved and judged in order. When a competitor solves a puzzle, he or she will submit the puzzle to their grader and will then wait for 30 seconds while grading is completed. If there is any mistake in the solution, the grader will return the puzzle. The competitor will have to fix any mistake and resubmit the puzzle, waiting for an additional 30 second period while it is graded. After the first person finishes completely, the round will be ended and new champions titled (e.g., “World Shading Puzzle Champion”)."

There were no team playoffs.

Contest Details edit

The rounds were reordered during the contest due to team rounds not printed on time, but the round numbers remain the same as in the IB.
