Game basics

Fill in the blank squares with numbers from 1 to 9. Your aim is to find the right numbers for the right squares so that the Sudoku gets completely filled with the numbers 1 through 9, but in a way that each number occurs only once in every line, only once in every column, and only once in every 3×3 block on the Sudoku board.

Starting a game

If you have an unfinished Sudoku game stored in the browser memory, there will be an option to continue where you left off by pressing the “CONTINUE” -button that appears under the play-button.

Sudoku strategy tips

Begin by looking for rows, columns, or blocks that already have several numbers. It’s easier to spot missing numbers in these areas.
Find cells where only one number can fit (often called “naked singles”). These are the easiest to fill in.
For each empty cell, list the possible numbers by eliminating those already present in its row, column, and block.
Work through the puzzle gradually. Focus on one area at a time rather than trying to solve everything at once.
Use the 'Notes' function to show small numbers in a cell representing possible candidates.
