Global Entropy: Group the digits 1-9 into low(123), middle(456), and high(789) digits. Every 2x2 cell group in the puzzle must contain at least one digit of each group.
X-Sums: Digits on the outside of a row or column indicate the sum of the first n digits, n being the first digit in that row or column
