Thanks Riad for the wonderfully crafted puzzles. Though I was able to complete only two puzzles, all the types were innovative and a gave good work to our brain cells.

Congratulations to Hideaki, Nikola and Daisuke! I note that Hideaki two years ago, also won with a bonus in September Sudoku Contest.
Thanks to all the participants and those who helped in organizing the Contest!
Also I want to note the result of Seungjae Kwak, which when tested was within 100 minutes.
