This is one my most popular puzzle: The Sumo which contains 13 Sudoku gridsLike each Sudoku variant with many Sudoku together, each Sudoku grid is not resolvable by itself, you need to take in account the clues from the neighboring grid At first the Sumo command respects because you must solve 13 Sudoku, so it is difficult to resolve this puzzle in a waiting room. But for the newcomer to Sumo, don’t be intimidated by this puzzle. You need only more concentration (a little more time) to take the challenge.
Try it you will love it.
