It's been a while, but I've made my fifth Jigsaw killer with digits 007.
Instead of 1 to 9 every row, column and jigsaw-piece has to be filled with the digits 0, 0, 1 to 7.
The (sum)cages are given a colour and have all a size of five cells. I have made a nice pattern with eight different shapes of 5 cells.
Because of a unique solution with this cage pattern, I had to place two givens. It's a pity and made the puzzle too easy.
To make it a bit harder again, I removed the sums of the two middle cages (pink and green).
Maybe it's a challenge for some great puzzlemakers on this forum to produce a similar puzzle (digits 1 to 9 is also ok) without givens that is logically solvable...
Enjoy!
