Black dots join 2 cells with one twice the value of the other. Not all black dots are shown.
The diagonals each have all the digits 1-9 on them.
Solve the puzzle online at F-Puzzles or CTC.
* I have set this puzzle as two star, but perhaps the break-in that is the point of the puzzle is more difficult to spot.
