Normal sudoku rules apply. Any set of three sequential cells along an entropic line must contain a low digit (1-3), a middle digit (4-6), and a high digit (7-9). Each line must contain exactly one friendly cell (friendly cell must contain digits which match at least one of the row, column, or box number).
