Serbian Frame Sudoku appeared in the 2nd round of the World Puzzle Federation Sudoku Grand Prix 2016. As this Sudoku type was a new Sudoku variation, I created a few puzzles to practice for this championship. There is another Serbian Frame Sudoku puzzle that I published earlier with the title Serbian Frame Sudoku (Fun With Sudoku #185). This is my second puzzle of this type, and I will rate it as difficult. Let's see if one can solve this Sudoku puzzle in less than 5 minutes.
This Serbian Frame Sudoku, I am posting in The League of Extraordinary Ladies & Gentlemen as the 169th puzzle in this series.
