Every Ultimate Sudoku puzzle starts with a partially filled grid. Your task is to figure out the missing numbers, using these rules:

• Use only digits 1 to 9.

• Each digit can appear once per row.

• Each digit can appear once per column.

• Each digit can appear once in every 3x3 block.

It’s that simple — and that challenging.

Choose Your Game Mode

• Ultimate Sudoku offers three interactive ways to play, tailored to your style:
• Cell First Mode: Click on any empty cell, then choose the number you want to enter. This method is ideal for scanning the grid and making strategic decisions one square at a time.
• Number First Mode: Pick a number first, then click the cells where it belongs. This mode is great if you want to focus on one digit across the entire puzzle.
• Note Mode: Not sure yet? Enter small, penciled-in possibilities using the number buttons or your keyboard. Perfect for narrowing down tricky sections and refining your strategy.

Tips for Mastering Ultimate Sudoku
