Logic Masters Deutschland e.V.

Paint some squares black to create a continuous wall. Number/s in a square indicate the length of black cell blocks on its neighbouring cells. If there is more than one number in a square, there must be at least one white cell between the black cell blocks. Painted cells cannot form a 2x2 square or larger. Additionally, all unpainted cells should form 12 different pentominoes. The pentominoes may be rotated and/or mirrored, and cannot touch each other from the sides. There are no wall or pentomino segments on cells containing numbers.
