NZ Sudoku and vaki ® Puzzle Championships

2017 NZ Open vaki ® puzzle and Sudoku Championship

The 2017 NZ open vaki ® puzzle and sudoku championship will be held, as an online event from 1.00pm Wednesday 21 June until 1.00pm Sunday 25 June.

Competitors in the sudoku and vaki ® puzzle championships play puzzles online (i.e this is a paperless competition). There are two types of puzzles - classic sudoku and vaki ® puzzles. The puzzles are scored. In both classic sudoku and vaki puzzles the puzzler starts with some points, loses one point for every second spent solving, loses points for each mistake made, and gains points for every symbol correctly placed. How many points are gained or lost depends on the type of puzzle being played and the difficulty chosen by the puzzler.

Competitors have 30 minutes and their top four puzzle scores are combined to give a total score. Competitors are allowed to select the type of puzzle and difficulty for each puzzle. A competitor may solve, for example, ten puzzles in their 30 minutes and partially solve 3 more. None of the scores from the partially solved puzzles will count, and of the ten solved puzzles the top four scores will count.
