Sudoku is a super fun puzzle game where you fill a big square with numbers from 1 to 9! The square is divided into smaller boxes, and the tricky part is that you can’t repeat any numbers in the same row, column, or little box. It's like a number treasure hunt! Each puzzle starts with some numbers already filled in, and you have to use your brain to figure out where the missing ones go. You can play it on paper or on the computer. It’s a great way to challenge yourself and see how smart you really are!
