Universal Sudoku Online

Universal Sudoku is a classic Sudoku experience with a dedicated following. It is a great way to exercise your brain and improve your problem-solving skills. Put your logic skills to the test as you fill a 9x9 grid with the numbers 1-9. Each row, column, and 3x3 box must contain all digits without repetition. Solving Sudoku puzzles can also be a relaxing and enjoyable pastime.  

How To Play Universal Sudoku

Examine the partially filled grid. Use logic to deduce the missing numbers in each row, column, and 3x3 box. Start by looking for cells with the fewest possible numbers. Remember: no row, column, or 3x3 box can have a number repeated. Look for spots where a number can only fit in one place to help you solve the puzzle. As you progress, you may find it helpful to use a process of elimination to narrow down the possibilities for each cell.
