United Sudoku Triples Sunday by Knight Features
Type: Number Other
Sudoku Triples consists of three standard Sudoku panels, sharing one set of 3x3 boxes. Each row, column and 3x3 box must contain the numbers 1-9 with no repeats. Each 3x3 box in the shared section of the three panels is filled in identically. Therefore, finding a number in one box in the shared section advances the other three boxes.
