Thanks to Alok Mittal for introducing me to Ken Ken puzzles through his Mathematical Circle classes – I spent a good chunk of my last week trying to solve the Ken Ken puzzles. Liked them so much, that I thought it would be worth sharing them.
Ken Ken puzzles are like a Sudoku, in the sense that you have to fill out unique number without repetition in every row and column, and also satisfy the specific condition in each of the bolded areas (condition specified in top left). Detailed instructions on this link:

As always, please send your answers directly to me at firstname.lastname@example.org. If you like the puzzle, please share it with others. If you have interesting puzzles to share, please send them to me at my e-mail given above.
Happy Ken Ken’ing!
