## Little Killer Sudoku on Pentominoes

(Eingestellt am 28. Juli 2020, 14:14 Uhr von psams)

Rules

"Sudoku Cells" in a 9x9 grid are pre-colored and marked with square frames.

The 15x15 grid must be entirely filled with colored Pentominoes. Pentominoes of the same shape or color may not share an orthogonal edge. Some borders between pentominoes are already drawn. Every Pentomino must include at least one "Sudoku Cell" except for one red Pentomino marked with the white star. A letter in the grid signifies that cell is a part of the corresponding pentomino.

Normal Sudoku rules apply. Digits are only placed in the Sudoku Cells.

P, W, F type pentominoes only contain digits from the Fibonacci sequence 1, 2, 3, 5, 8.

Sums are given for marked diagonals, which can include repeats.

Note

There is a path of logical deduction from start to finish. Guessing or trial and error is possible but not required to solve this puzzle.

Difficult to assess the difficulty of this puzzle; each step is fairly simple, but there are quite a lot of them until it is finally solved, and at least using the "notation system" I used (ie, M\$ Paint), in the end the "paper" became rather messy. A nice puzzle, but lacking that extra "wow factor" (however, the disambiguation of 2+8 or 5+5 in the beginning of the last phase was really elegant...)

I prophecied the creation of a 16×16 pentominoe soduko last time, but you went ahead and over-delivered with 25×25.
