Logic Masters Deutschland e.V.

Normal Sudoku rules apply. Shade some cells such that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected and no 2x2 squares are entirely shaded or unshaded. Additionally there cannot be any T shaped junctions of shaded cells.
I.e. A shaded cell may orthogonally touch 1, 2 or 4 shaded cells but never 3.

Clues outside the grid count how many shaded cells appear in the row or column.

A digit in a shaded cell indicates how many times that digit appears in shaded cells.

A white dot separates consecutive digits.
