Logic Masters Deutschland e.V.

Rules: Each region has exactly one shaded “block” consisting of orthogonally connected cells inside the region. Numbers represent the amount of cells that are the same type (shaded or unshaded) in its region, including itself. All shaded cells are connected to each other orthogonally. Unshaded cells are either a group of 1 or are orthogonally connected to all unshaded cells that aren’t. There must be at least one pocket (unshaded group of 1). There are an equal amount of shaded cells and unshaded cells. Click the image to play on Penpa+.
