Generate a standard sudoku puzzle:
In[1]:= 

Out[1]= 

In[2]:= 

Out[2]= 

Solve the resulting sudoku puzzle to confirm that the reference puzzle is obtained:
In[3]:= 

Out[3]= 

Generate a 16×16 sudoku puzzle with 70% of the elements exposed:
In[4]:= 

Out[4]= 

In[5]:=

If the specified exposed percentage is too low, then the function will return a puzzle with the smallest number of elements exposed such that the resulting sudoku puzzle is unique:
In[6]:= 

Out[6]= 

In[7]:= 

Out[7]= 

Solve the resulting sudoku puzzle to confirm that the reference puzzle is obtained:
