Sudoku9 Instructions

This is a version of the Sudoku puzzle (also called Su Doku, Number Place Logic Puzzle or sometimes even Suduko!) based on a 3x3 grid and the numbers 1 to 9. It is rated as "easy" difficulty at this level.

Start the puzzle by pressing the green button as usual, then you will enter the main game screen. You will then see a number grid containing the Sudoku puzzle with the starting numbers in black. You will also see three other buttons : a "check" button at the lower right that you can click to see if you have got all the numbers right, a red "clear" button at the top right which restarts the game (be careful not to press it during the game), and a "Notes on/off" button at lower left.

To add a number to any of the squares, drag one of the coloured numbers which are just below the number grid into the centre of one of the squares. The number should then appear in that square in the colour blue. Make sure that you do not try to drag it on top of one of the starting numbers (this is not allowed and you will hear a warning sound) and that the "Notes" button is set to "off". If you put the wrong number down, then just drag and drop another one on top of it.

The "Notes" button allows you to add up to four numbers in the corners of each of the squares as a note to which numbers you think may be the correct one. This is a useful feature to have when the puzzle gets complicated!

To add a note, click on the "Notes" button, then drag one of the coloured numbers below the number grid into one of the squares. If the number is already there as a note, it will be removed, otherwise it will be displayed in the corner of the square. You can only have up to 4 notes per square. When you set the number of the square (when the "Notes" button is off), all the notes in the corners will be removed.
