Logic Masters Deutschland e.V.

As I received plenty of positive feedback for my last one, I created another cageless (X) killer sudoku. It features some logical ideas that I did not include in the first one (and I think there is much more yet to be explored).

Rules:

Standard sudoku rules apply. In addition, cells are grouped in 'cages'. A 'cage' is a group of orthogonally adjacent cells. Numbers must not repeat in a cage. Cages must not overlap.

The clues outside the grid in the form of m(n) indicate, that the x-th cell of the row/column is part of a cage with the sum of m, consisting of n cells. X is the first number in the row/column. In the example below, the clue 7(2) indicates that the x-th cell (in this case: the 2nd cell) is part of a cage adding up to 7, consisting of 2 cells.

There is a logical solution path. Entry point is a bit tricky, but then it should be roughly the same level of difficulty as the first one.

Have fun!
