Sudoku

Fill the 9×9 grid so that every row, column, and 3×3 sub-grid contains the digits 1 through 9 without any duplication. Based on the given numbers and rules, players must logically deduce and fill in the remaining blanks step by step.

Sudoku puts your logical thinking, deductive reasoning, and patience to the test, making it both highly challenging and immensely rewarding. Every single puzzle features a unique solution, and cracking it relies entirely on your careful thought and inference.
