The Webinar on Sudoku and Some Curious Variants took place on Thursday, February 25th, 2021 from 2 pm until 3 pm, with Dr. Alexander Diaz-Lopez, Professor of Mathematics at Villanova University in Pennsylvania, as our invited speaker. This virtual event was free and open to the general public.
The invited speaker started the virtual event by explaining how to play sudoku and by briefly sharing the history of this puzzle. Alexander Diaz-Lopez then answered several popular questions on the connections between sudoku and mathematics, like how many sudokus are there, what makes a sudoku easy or hard, and if there is any strategy to solve a sudoku. The speaker also presented on several curious variants of sudoku, like Diagonal Sudoku, Sum Sudoku (which we called SudoKen in our Tenth Math Jamboree), and 3D Sudoku.
