Heteromino (1118)
Instruction:
Divide the grid into triominoes along the dotted grid lines such that triominoes of the same shape never touch along an edge. Rotations and reflections of a triomino do not count as the same shape. Some cells may be connected with a line; those must be part of the same triomino. Some cells may be separated by a thick border; those must not be part of the same triomino.
