Logic Masters Deutschland e.V.

Rules

• Normal Sudoku rules apply.
• Shapes: A digit in a (blue) shape (circle, square or diamond) specifies how often that digit appears in different shape types.
  Example: A 3 in a circle indicates that in exactly three shapes that are square or diamond, there is a 3.
• Disjoint Groups: Cells that appear in the same position relative to their boxes may not contain the same digit.
• Arrows: Digits on an arrow sum to the total in its circle.
