Play Fun Sudoku Free Online

Complete a number grid using the values already on the board.

How to play

Pick an empty cell and choose a number that fits its row, column and box. Read the grid before using the number picker.

Tips and strategies

Start with rows, columns or boxes that already contain most numbers. When a cell could take several values, leave it and look for a definite placement elsewhere.

Use a short first session to find a rhythm. Change it when an obstacle breaks the pattern.
