Hi all, Pahzzles is hosting a special themed Sudoku variant contest. It has already started but will be open for ~2 weeks. The rules for each puzzle aim to be novel (and may be slightly experimental). There is a range of difficulties from beginner-friendly to extremely challenging. The puzzles are all meant to be solved directly in the browser. The site requires registration but no additional contest registration is required to participate in the contest.
