About Sudoku Puzzle

Sudoku Puzzle uses an 81-square grid where every blank must receive a number from 1 through 9. The rules are precise: a number cannot repeat within its row, column, or region, so each entry narrows the possibilities around it.

The appeal comes from building a complete solution through logic rather than guessing. Filling a well-supported square can reveal options elsewhere in the grid, creating a steady chain of deductions. Whether you are learning the format or aiming for a strong score, each puzzle offers a focused test of concentration.

How to Play Sudoku Puzzle

Use a mouse click or a tap to select the square you want to work on.

Fill the empty squares with numbers from 1 to 9 while following the row, column, and region rules.

Check the surrounding row before placing a number, then compare it with its column and region.

Continue linking deductions across the 81 cells until the grid is complete.

Track your progress toward the highest score as you solve each puzzle.

Tips & Tricks

1Begin with a blank that has only a small number of possible digits based on its row, column, and region.
2After placing a number, recheck nearby spaces because one entry can remove that option from several locations.
3If a choice feels uncertain, leave the square open and work on another part of the grid until the rules provide stronger evidence.
