Spiral Galaxies (Tetrominoes) (854)
Instruction:
Divide the grid into polyomino-shaped regions such that each cell is in exactly one region. You may only draw on the grid, as indicated by the dotted lines. Each region is either a "galaxy" or a "shaded tetromino". Each galaxy must be rotationally symmetric and contain exactly one dot at the point of symmetry. Each tetromino shape is used as a shaded tetromino at most once, but can be rotated or reflected. Shaded tetrominoes cannot touch along edges or corners. Some shaded tetromino cells may be given to you.
