Logic Masters Deutschland e.V.

When starbattling, what is better than having a break for a sandwich.

Rules: Fill the grid so each row, column and 3X3 box contains the numbers 1-7 and two stars. Stars must not touch each other, not even diagonally. The clues outside the grid are sandwich clues and show the sum of the digits between 1 and 7, in the corresponding row or column. The value of stars is zero (0). For example, for a 6 clue the combinations: 167, 1*67, 72*4*1, are all valid.

It's a combination of puzzles I like, so I hope you will enjoy solving it.
