Sudoku is Oops! All Twins by Michael Lefkowitz, App variant is OTHER


Place TWO digits from 1-8 in every cell so that each digit appears exactly once in every row, column, and 2x2 box. The smaller digit should go in the upper left, and the larger one in the lower right. A cell can take the value of either of its digits. A number on a diamond is a sum of the cells it separates. A number outside a row a column is a sum of that row or column.
