It's possible to make something similar with Excel. Something like

  A1 = "X"      B1 = Integer( 6 * Random() + 1 )
  
  A2 = "Y"      B2 = Integer( 6 * Random() + 1 )
  A3 = "X+Y"    B3 = B1 + B2
  
  A4 = "Z"      B4 = 7 - B1
  A5 = "X+Z"    B5 = B1 + B4

And then press "F9" to refresh the random values and get new ones.
