• Each row and column should comprise of three 3-digit primes.
• In each of the second, fifth and eighth rows and in each of the the second, fifth and eighth columns, the three 3-digit primes, in SuDoDu fashion, every digit 1 to 9 will be used once.
• In all other rows and columns digits may be repeated.
• All 3-digit primes should be distinct.

More than one solution may exist.
