Although instructions for Sudoku in the press often say “There’s no mathematics required”, in fact there are many mathematical connections, going back to Euler. I will start off by explaining how the ingredients of the puzzle came to be developed by mathematicians. Sudoku is closely related to Latin squares, which have applications in statistics and cryptography. I will also talk about a variant of Sudoku due to Robert Connelly, whose analysis involves other parts of mathematics such as affine geometry over finite fields and error-correcting codes.
