Pendoku

(Published on 12. January 2021, 08:08 by Terttu5)

This is a combination puzzle of pentomino puzzle and killer sudoku.

Divide the sudoku grid into pentominoes (five-cell regions) so that no two pentominoes of the same shape (including rotations/reflections) share an edge. A cell with a letter in it must be part of the pentomino shape normally associated with that letter. Not all shapes must be used. There is only one empty cell in the grid which is already marked in box 9. The number in the grid is given number for the sudoku and doesn't affect the pentomino shapes.

After you have done the pentomino part you need to finnish the puzzle as a killer sudoku. Cage totals are for the pentomino shapes and they are marked next to the grid. Killer sudoku uses regular killer sudoku rules:
Fill all rows, columns and 3x3 region with numbers 1-9 like in regular sudoku.
Every cell is a part of a cage.
Make sure the cells can be added up to the sum of its cage.
Numbers cannot repeat within cages.
Numbers cannot repeat within a single row, column or 3x3 region.

Solution code: Row 2 (left to right) and column 6 (top to bottom), 18 digits. Only enter the digits from sudoku solve, no spaces.

I missed this when it first appeared. But before posting a hybrid of a pentominous puzzle and a sandwich sudoku (00063P), I checked to see if any similar puzzles had already been done, and found this.
Nice puzzle! My experience was the opposite of Franjo's: I had a hard time getting started on the pentominous part, but the killer was fairly easy.

Quite easy Pentominous, but the Killer was hard - for me. Nice Puzzle!

@bigger still learning to use the site, so just road your comment. Nyt even shure if you can see this comment. This puzzle was created to be solved as you said. I will keep in mind your comments if&when creating another hybrid like this.

Thanks for the Feedback. I also hope more people will give it a try. I don’t think it is too complicated as a puzzle. I myself don’t have strong experience on pentominous Solving, so it should be relatively easy part. Maybe it just isn’t as interesting hybrid for solvers as I tought. :)

This looks like a GREAT idea for a hybrid puzzle. At this point, it looks like only 1 person has solved it. If users aren't familiar with the wonderful Pentominous puzzle type (e.g., see https://www.gmpuzzles.com/blog/category/regiondivision/pentominous/), they should check it out. Combining Pentominous with Sudoku in the way you have done here seems brilliant and fun. I hope more give it a shot.
