Logic Masters Deutschland e.V.

• Normal sudoku rules apply: Place the digits 1-9 once each in every row, column, and 3x3 box.
• Modular Lines: each consecutive group of 3 cells on a teal line must contain one digit from each of the following sets: [1,4,7], [2,5,8], and [3,6,9].
• X-Sums: A clue adjacent to a row or column represents the sum of the digits in the first X cells in that row or column, where X is the first digit in that row or column. The clue outside the top left corner of the grid is a diagonal X-Sum, which represents the sum of the first X digits along that diagonal, where X is the digit in row 1 column 1.
