Happy Sudoku

Welcome! 🎉

Sudoku is a classic number puzzle that trains your logic and patience. Fill the grid with numbers 1–9 following simple rules — perfect for a quick brain workout or a relaxing break.

How to Play:

• Fill every empty cell with a number from 1 to 9.
• Each row, column, and 3×3 box must contain all numbers 1–9 without repeating.
• Numbers already on the grid are fixed — you can’t change them.
• Choose a difficulty, start a new game, and have fun!
