Today’s puzzle isn’t of a type that’s established or named (at least, not to my knowledge). However, it’s a very natural ruleset inspired by the popular challenge of arranging different pentominoes into a rectangle, so I’m also giving it a very natural title: Pentomino Division!

Rules: Divide the grid into pentominoes of all different shapes, counting rotations and reflections as the same. Borders must separate two different pentominoes.

All possible pentomino shapes are shown for your convenience. The orientation they’re shown in is not necessarily their orientation in the puzzle.

⚠️ The example puzzle uses tetrominoes instead of pentominoes.
