How to play
A Hyper Sudoku puzzle is very similar to a normal Sudoku puzzle, but there are four extra
regions. In this puzzle you will see there are four 3x3 shaded areas. Each of those shaded 3x3 areas
must contain the number 1-9 once and only once.
You can use all of the same rules when solving a Hyper Sudoku Puzzle, but you will also need to make use
of the four extra regions.
Look at the highlighted cell in this puzzle. We know that the top-right extra 3x3 region must contain the
number 2 somewhere. However, the top-right, top-center, and center-right normal 3x3 region all contain a 2
already. That only leaves the highlighted cell from the extra region, so the hilighted cell must be a 2.
Have a look at the Hyper Sudoku puzzle to the left, you can fill in the highlighted cells using the
techniques you have just learnt.

There are two ways to play a Sudoku puzzle, you can just use the mouse/touchscreen, or you can use the mouse and keyboard.
You can switch between the two methods any time you like, and can use a combination of both.
Playing with a mouse/touchscreen.
- When you have found a square where you can enter a number, click/touch that square. The square will turn light blue.
Above and below the puzzle is the number selection. Click/touch the number you want to enter in to that cell.
If there is already a number in that square, it will be over-written.
- If you want to enter a pencil mark, click/touch the square you want to put in a pencil mark. It will turn light blue.
Click/touch the pencil icon above or below the puzzle. This icon will turn light blue, and you are now in pencil marks mode.
Whenever you click/touch a number now, a pencil mark will be put in the square instead.
To remove a number as a pencil mark, make sure you are in pencil marks mode, and click/touch the number again.
You can exit pencil mark mode by clicking/touching the pencil icon, it will turn back to normal.
- If you want to clear a particular square, make sure that square is selected and is in light blue.
Click/touch the eraser icon. If there is a number in that square, it will be removed.
If you click/touch it again, any pencil marks in that square will be removed.
Playing with a mouse and keyboard.
- You will need to select a square by clicking on it with the mouse, it will turn light blue.
You can change the current square by using the cursor keys on your keyboard.
- To enter a number, press that number on the keyboard. If there is already a number in that square, it will be overwritten.
To remove a number, press the backspace or delete key on your keyboard.
- To enter a pencil mark, press control, shift, or alt on your keyboard at the same time as pressing a number key.
Do the same thing again to remove that pencil mark.
