Logic Masters Deutschland e.V.

Rules

• Normal sudoku rules apply.
• A circle containing an operator and an integer value indicates that both diagonal pairs of digits around the circle give that value when the operator is applied to them. For example, a 3/ clue would say that both diagonal pairs are in a 1:3 ratio, such as 39 and 62.
• A question mark indicates that the integer value for that clue must be determined by the solver.

Solve in f-puzzles or CTC.
