You can also find Number Cross Addition under the name pluszle puzzles. With these logical puzzles 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 sum of the remaining numbers corresponds to the number at the top and left outside the grid.

By clicking twice on a gray box, 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.
