Logic Masters Deutschland e.V.

Rules

• Normal sudoku rules apply.
• Draw a non-intersecting orthogonally connected loop through the centers of some cells. The loop is made up of segments of length 3, which are connected to each other by a cell on the loop.
• The length 3 segments all have the same total.
• Each connecting cell has a different digit. Every row, column, or box has exactly one connecting loop cell. For example, these could be some of the digits on the loop ...7-(135)-3-(621)-5-(414)-2...
• Some segments could not be used in the loop because they had the wrong length, however, they still have the same total as those on the loop. They are scattered around the grid and are shown as double lines. Unused segments do not overlap with the loop.
• For any two digits connected by a black dot, one is twice the other. Not all black dots may be given.
