Normal sudoku rules apply. Apart from the central cell, the grid must be fully tiled using nine different types of pentomino, rotated or reflected as necessary, but never sharing an edge with another of their own type. Numbers in the shapes follow these rules: L&U: contain unique digits; N&T: adjacent digits are non-consecutive; P&V: adjacent digits are consecutive; W&Y: contain unique digits that sum to a multiple of 3; Z: adjacent digits differ by more than 5.
