Rules[edit]

Tournament Structure[edit]

The top 10 competitors from the individual competition will qualify for the playoffs. In case of a tie, all players with the same score will compete in the corresponding round. Ties are broken by score without time bonuses, score in Round 9, extra puzzle.

In each round of all play-offs, the competitor in the best position in this round will start solving at 25:00. The competitor in the worst position in this round will start solving at 20:00. Starting times of other competitors will be calculated according to their points, proportionally.

Finals will be divided into three rounds. The first round will feature competitors who finished in positions 7-10. The winner will progress into the second round along with competitors who finished in positions 4-6. The first-round winner will have a staggered start as determined by the 7th place competitor. The same goes for the third round. The third round will determine the podium places for the 25th World Puzzle Championship.

Round Structure[edit]

The time limits for each round will be 25 minutes. In each round of the finals, 4 puzzles will be solved. Their puzzles will be chosen by play-off competitors from the set of puzzles in the corresponding section of the Instruction Booklet.

For each round of finals, 8 different puzzles are prepared. The competitor in the best position in this round will choose one puzzle, which will be solved first in this round of the finals, and one puzzle, which will not be solved at all. The competitor in the second-best position will choose from the remaining 6 puzzles, one puzzle, which will be solved second, and one, which will not be solved at all. The competitor in the third-best position will choose from the remaining 4 puzzles, one puzzle, which will be solved third, and one, which will not be solved at all. The last competitor will choose from the remaining 2 puzzles, one puzzle, which will be solved last in this round of the finals.

The first and second round of the play-off stops either with the end of the time limit or when the first competitor solves correctly all puzzles in the round, whichever is earlier. The third round of the play-off stops either with the end of the time limit or when 3 competitors solve correctly all puzzles in the round, whichever is earlier.

The rank for a playoff round is determined by a) number of correctly solved puzzles, b) time of the last correct submission, c) score in preliminary rounds. In playoff rounds 1 and 2 we care only about the winner, other players are ranked according to the score in preliminary rounds. In Round 3, all positions 1-4 are determined by playoff results.

Scoring and Submission[edit]

When a playoff competitor completes a puzzle, he/she must raise his/her hand to indicate to a judge to enter the submission period. The entire puzzle will then be checked over the next minute. After one minute, if the puzzle is correct, the judge will allow the competitor to begin the next puzzle. If the puzzle is incorrect, the judge will return the incorrect puzzle to the competitor. The competitor can resubmit a returned puzzle at any time, and will again enter the submission period.
