With the Number Cross Multiplication you can improve you knowledge of the times tables. You get a grid full of digits. Outside the grid at the top and left there are also numbers.

You now have to delete digits in the grid (= a cross appears) so that the multiplication of the remaining digits corresponds to the number at the top and left outside the grid.

By clicking twice on a gray box in the grid, it will turn WHITE. This means that you need this digit.

So to solve a number cross puzzle:

• The cells you need must become WHITE
• The cells you don't need must have a CROSS

When you click on a number outside the grid, then the background becomes WHITE. You can use this to indicate that you have found the digits for that number.
