Logic Masters Deutschland e.V.

The standard Sudoku rules apply.
When a number in a cell matches the number of its row, column, or box, we call that a friendly cell. The clues outside the grid show how many friendly cells are in the row or column.
The numbers indicate the total count of orthogonally connected groups of cells. There must be at least one cell separating two groups of cells.
Any three consecutive digits in a horizontal or vertical direction in the grid, there will be one from each of the sets of numbers: [147], [258], and [369].
