About Sudoku

This Japanese classic needs no math wizardry, just clear thinking and patience. Each game starts with a partially filled grid, and everything else comes down to pure logic.

How to play Sudoku

The goal of Sudoku is to fill in a 9×9 grid with digits so that each column, row, and 3×3 section contain the numbers between 1 to 9. At the beginning of the game, the 9×9 grid will have some of the squares filled in. Your job is to use logic to fill in the missing digits and complete the grid. Don't forget, a move is incorrect if:

• Any row contains more than one of the same number from 1 to 9
• Any column contains more than one of the same number from 1 to 9
• Any 3×3 grid contains more than one of the same number from 1 to 9

Sudoku Tips

Sudoku is a fun puzzle game once you get the hang of it. At the same time, learning to play Sudoku can be a bit intimidating for beginners. So, if you are a complete beginner, here are a few Sudoku tips that you can use to improve your Sudoku skills.

• Scan rows, columns, or 3×3 blocks that already hold five or more numbers. The unused digits often have only one possible spot.
• Mentally split the board into three vertical bands and three horizontal bands. If two copies of a digit already sit in the same band, the third copy must land in the only 3×3 block left in that band. Check the empty cells there to nail the exact square.
