Look in this 6x6-table. 

It has two entries: the row at the top and the column at the left.

These entries are possible values from two cubes.

The cells in the table contain values abs(row-column).

You can see that the value of 4 does present 4 times in the table,
while the value of 5 does present only 2 times.


Conclusion.  Is the game fair ?   The answer is "NO".
