Sudoku, which means "the numerals must remain single," was a puzzle craze that spread throughout the world by the early 2000s. People often attribute it to Japan, but its origins can be traced back to 1783 when Leonhard Euler, a Swiss mathematician, created "Latin Squares," which employs the same concept of having only one symbol appear in a row or column. It's believed that some form of the puzzle existed even before that in ancient China and Europe.
If the popularity of sudoku apps and the proliferation of new puzzles published in newspapers is any indication of the universal appeal of Sudoku, we can all agree that it’s a puzzle that has transcended borders. Anyone who understands its concept, whether young or old, can do it. The logic behind solving a Sudoku puzzle is straightforward. You fill a 9x9 grid with digits so that each row and column can only have that number once. For "very easy" levels, almost all boxes are pre-filled with numbers that can help you quickly solve the puzzle. The record for the quickest time to solve a very easy Sudoku puzzle was just over a minute.
