This year, we've added a special bonus Killer Sudoku tournament to the schedule.
According to Wikipedia, killer sudoku "is a puzzle that combines elements of sudoku and kakuro. Despite the name, the simpler killer sudokus can be easier to solve than regular sudokus, depending on the solver's skill at mental arithmetic; the hardest ones, however, can take hours to crack." Killer Sudoku follows the same sudoku rules except you are given clues in the form of totals for a group of boxes which will give clues from which you can deduce the numbers.
Haven't tried these puzzles yet? Don't worry, there will also be a workshop on Saturday to get you all up to speed before the competition.
