Sudoku Puzzles
Sudoku puzzles are logic-based number puzzles that require players to fill a 9x9 grid with numbers so that each row, each column, and each of the nine 3x3 subgrids contain all of the numbers from 1 to 9. The objective is to fill in the grid in such a way that there are no repeating numbers in any row, column, or subgrid. Sudoku puzzles come in various levels of difficulty, ranging from easy to very challenging, and have become a popular pastime for people of all ages.
