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 each puzzle in a round. At the judge's discretion, 0.6 × bonus will be awarded in the case of a single minor mistake in no more than 1 puzzle. For the avoidance of doubt, a minor mistake is considered at most two incorrectly filled cells in at most one of the puzzles.
  • 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 there are any mistakes, then no bonus will be awarded.

Individual Playoffs[edit]

The top 10 competitors from the individual competition will qualify for the playoffs. In the case of a tie, all players with the same score will compete in the corresponding round.

Time differences will be calculated proportionally based on the top score and the 10th place score. The difference between 1st and 10th place will be 10 minutes.

Finals will be divided into three rounds. The first round will feature competitors who finished in positions 7-10, with staggered starts determined by points' differences. The winner of the first round will progress into the second round along with competitors who finished in positions 4-6. First round's winner will have an offset as determined by the 7th place competitor. The winner of the second round will progress into the third round along with competitors who finished in positions 1-3. Second round's winner will have an offset as determined by the 4th place competitor. This round will determine the podium.

Team Playoffs[edit]

The top 4 teams after the preliminary rounds will qualify for the playoffs. In case of any a tie, all teams with the same score will compete in the finals.

Teams will start the playoff with time offsets based on the preliminary results. The time differences will be calculated proportionally to the team points from preliminary rounds. The difference between the 1st and 4th team will be 6 minutes.
