Pentomino-Rundreise
(Published on 16. August 2020, 00:23 by Phistomefel)
About the rules:
- Every cell of the grid has to be part of exactly one pentomino.
- Orthogonally adjacent pentominos have to be different from each other (i.e. they cannot be transformed into each other by reflection and rotation).
- In addition, a round trip has to be drawn into the grid. It runs horizontally and vertically between the centers of cells. It may not cross or touch itself.
- A clue in a cell indicates how many cells of the according pentomino are passed through by the round trip.
- Every pentomino contains at most one clue. A pentomino without clue has to be visited by the round trip at least once.
Here are all 12 pentominos shown for overview. Many thanks to uvo for the graphics!
Now for the puzzle. It is also available online via Penpa. Have fun solving!
Solution code: For every cell in the 2nd and 7th row lying on the round trip, give the capital letter of the pentomino to which the cell belongs. In the example on the 7x5 grid, the solution code for the 5th column would be 'IPUU'.

Thanks, filuta! And also sorry for the headache. If I recall correctly, the bottom right corner also gave me some headache during construction because I overlooked an option allowing for multiple solutions.

this was also very cool, although the bottom right corner gave me some headache

I kept catching myself singing "One Thing Leads to Another" as I solved this, but I quite enjoyed the logic. The hard part was entering the code on here...

One of my favorite puzzles, and the first puzzle I solved on LMD. I wanted to look back on it and realized I must have first solved it while not yet a member, so I had to run through it again. This puzzle is one of the main reasons that I decided to try setting my first puzzle a few months ago. Many thanks for that!

Pentominos und Riundweg, immer wieder eine tolle Kombination. Für den Anfang habe ich etwas gebraucht (und erstmal das Beispiel gemacht...). Dann entwickelt sich aber ein lang anhaltendes Rätselvergnügen auf gutem Niveau. Kein Trial&Error, sondern (fast) die ganze Zeit nur Kombination gefragt. Echt toll gemacht. Weiter so!

Vielen Dank! Schön, dass euch das Rätsel gefällt. :)

sehr schönes Rätsel.

Tolle Konstruktion, sehr schöner Lösungsweg. Die 100% sind absolut verdient, aber die 5 Sterne finde ich etwas übertrieben...
Lasst euch nicht von den 5 Sternen abschrecken!

This was incredibly enjoyable! Didn't struggle with it as much as your other puzzles, but it's a worthwhile challenge nonetheless!

Unglaublich toll! Magisch, wie sich alles nach und nach ergibt. Hat mir sehr viel Freude bereitet.

@CilantroGamer: Thanks! :) I am glad you enjoyed it. This puzzle also has an English version - you can switch the language in the upper right corner of the website.

Great puzzle, found on CtC! Really fun and a cool concept. Also, the Google translation for the solution instructions was slightly ambiguous as to whether you submit the 2nd and 7th rows or the columns. It's the rows. (It just says 'lines'.)

Ganz klasse, wunderschön. Und knifflig bis zum Schluss. Hat viel Spaß gemacht!
@Statistica: Vielen Dank für dein Lob! Freut mich sehr, dass es dir gefallen hat.

@Genomico: Thank you very much your kind words about the puzzle.

Amazing puzzle! Very nice concept.
Interesting till the end. Challenging, but never too complicated that you need large bifurcations.
Such a joy solving it.
Thank you for the puzzle :)

Just joined today and it was my first puzzle that i solved in logic masters. Really loved the puzzle. I had just one mistake while solving which i was able to correct, still the puzzle was quite difficult.
on 18. August 2020, 09:06 by MagnusJosefsson
Brilliant puzzle! Consistently difficult, and great in that you have to manage the entire ruleset simultaneously throughout the solve. For me, the puzzle was quite difficult, and it was easy to make mistakes. But I persevered and started over/redid sections a few times because I liked it so much.

Thank you for your nice feedback, emmettcito and jesper! :)

Changed puzzle to avoid ambiguity of the round trip. The solution code is not affected.

Wonderful puzzle! This was very fun to solve.
