Logic Masters Deutschland e.V.

Rules:

Normal sudoku rules apply. (Place the numbers from 1 to 9 in every row, column and 3x3 box.)

In addition, there are numbers outside the grid.

Unlike normal sandwich clues, the numbers outside the grid tell the sum of groups of numbers that are outside the sandwich in its row/column. [1 and 9 are not included in the group as they are part of the sandwich]

[A sandwich is a group of numbers that are between 1 and 9 in a row/column]

If only one number is given for a row/column, there is only one group that is outside the sandwich.

If there are two numbers given, there are two groups that are outside the sandwich. They are always given in the order that they appear from the given clue.

In this example, 2 and 3 are on the left side of the sandwich, and 4 is on the right side. Therefore, the given clue is [5, 4]. The order of the clues for rows are always [left of sandwich , right of sandwich]. The order for columns are always [above the sandwich, below the sandwich]. For clues wih only one number, the group may be on either side of the sandwich.

Finally, the number in c2r5 is greater than the number in c3r5.

Enjoy!
