Normal sudoku rules apply. Apart from the central even cell, the grid must be filled with one or more pentominoes of each listed type, in which the top-left cell of the shape contains the given digit: 1=I, 2=W, 3=T, 4=L, 5=V, 6=X, 7=N, 8=Y, 9=P. Digits do not repeat in pentominoes, and two of the same type may not touch each other orthogonally. Cells joined by symbols are consecutive (white dot), have a ratio of 1:2 (black dot), or sum to five (V). Not all symbols are given.
