The brief
- Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box. - Modular lines: Any set of three adjacent digits along a modular line has three different remainders when divided by 3. - Killer cages: Digits in cages cannot repeat and must sum to the value shown in the upper left corner of the cage. - Ratio dots: Digits in cells separated by a black dot are in a 2:1 ratio.
