Divide the grid into pentominoes such that every cell in the grid is part of exactly one pentomino. Pentominoes of the same shape (rotations and reflections of a pentomino count as the same shape) cannot touch each other along an edge (but they may touch diagonally). Some letters are given in the grid. Each letter must be part of a pentomino with that letter’s shape. It is permissible for a pentomino to contain more than one letter. (It is possible for some pentomino shapes to never appear in the grid, or more than once.)
The letter-to-shape correspondence for pentominoes has been supplied for you.
Notes:Variants:
- Pentominoes (no letters are given): Divide the grid into 12 different pentominoes (rotated or reflected pentomino is considered the same).The black cells may not be covered by pentominoes.
